Topic: Multirobot Control Using Time-Varying Density Functions

 

Abstract: An approach is presented for influencing teams of robots by means of time-varying density functions, representing rough references for where the robots should be located. A continuous-time coverage algorithm
is proposed and distributed approximations are given whereby the robots only need to access information from adjacent robots. Robotic experiments show that the proposed algorithms work in practice, as well as in theory.

Topic: Wall-Following Control of a Hexapod Robot Using a Data-Driven Fuzzy Controller Learned
Through Differential Evolution

 

Abstract: This paper proposes the use of evolutionary fuzzy control for a wall-following hexapod robot. The data driven fuzzy controller (FC) is learned through an adaptive group-based differential evolution (AGDE) algorithm, which avoids the explicit usage of the robot mathematical model and time-consuming manual design effort. In the wall following task, the inputs of the FC are measurements of three infrared distance sensors mounted on the hexapod robot. The FC controls the swing angle changes of the left- and right-middle legs of the hexapod robot for proper turning performance while simultaneously moving forward. To automate the design of the FC and to improve the performance of control, an AGDE algorithm is proposed. In the AGDE-designed FC, a cost function is defined to quantitatively evaluate the learning performance of an FC based on data generated online. In the AGDE, the solution vectors in a population are adaptively clustered into different groups based on their performances at each iteration. To improve optimization performance, the AGDE adaptively selects components from either the group-based mutant vector or a typical population-based mutant vector in the mutation operation. Simulated and experimental results are gathered to verify the effectiveness and efficiency of the data-driven AGDE-based learning approach.

Topic: A Sensor-Based Dual-Arm Tele-Robotic System

 

Abstract: We present a novel system to achieve coordinated task-based control on a dual-arm industrial robot for the general tasks of visual servoing and bimanual hybrid motion/force control. The industrial robot, consisting of a rotating torso and two seven degree-of-freedom arms, performs autonomous vision-based target alignment of both arms with the aid of fiducial markers, two-handed grasping and force control, and robust
object manipulation in a tele-robotic framework. The operator uses hand motions to command the desired position for the object via Microsoft Kinect while the autonomous force controller maintains a stable grasp. Gestures detected by the Kinect are also used to dictate different operation modes. We demonstrate the
effectiveness of our approach using a variety of common objects with different sizes, shapes, weights, and surface compliances.

Topic: Automated Health Alerts Using In-Home Sensor Data for Embedded Health Assessment

 

Abstract: We present an example of unobtrusive, continuous monitoring in the home for the purpose
of assessing early health changes. Sensors embedded in the environment capture behavior and activity patterns. Changes in patterns are detected as potential signs of changing health. We first present results of a preliminary study investigating 22 features extracted from in-home sensor data. A 1-D alert algorithm was then implemented to generate health alerts to clinicians in a senior housing facility. Clinicians analyze each alert and provide a rating on the clinical relevance. These ratings are then used as ground truth for training and testing classifiers. Here, we present the methodology for four classification approaches that fuse multisensory data. Results are shown using embedded sensor data and health alert ratings collected on 21 seniors over nine months. The best results show similar performance for two techniques, where one approach uses only domain knowledge and the second uses supervised learning for training. Finally, we propose a health change detection model based on these results and clinical expertise. The system of in-home sensors and algorithms for automated health alerts provides a method for detecting health problems very early so that early treatment is possible. This method of passive in-home sensing alleviates compliance issues.

Topic: Security-Aware Modeling and Efficient Mapping for CAN-Based Real-Time Distributed Automotive Systems

 

Abstract: Security has become a critical issue for automotive electronic systems. To protect against attacks, security mechanisms have to be applied, but the overhead of those mechanisms may
impede system performance and cause violations of design constraints. To remedy this problem, we proposed an integrated mixed integer linear programming (MILP) formulation that is the first to
address both security and safety constraints during system mapping for controller area network (CAN) based systems [10]. However, its signal-based security constraints do not fully reflect real security requirements, and its objective function is to minimize functional path latencies rather than minimize security risk. Furthermore, its MILP-based approach has high computation complexity.
In this work, we present a new formulation that defines path-based security constraints and minimizes security risk directly, and propose a new heuristic algorithm to solve the formulation efficiently. Experiments on an industrial example show that our new algorithm achieves comparable solution quality as the MILP-based approach with much better efficiency.

Topic: Design and Operation of Secure Cyber-Physical Systems

 

Abstract: This letter proposes a holistic framework for the design and operation of secure and reliable resource-constrained cyber-physical systems. The proposed framework combines
control-theoretic methods, information security notions and computational models to characterize tradeoffs among different design and operation objectives. We quantify the intricate relation among control performance, system security and platform schedulability through a minimal set of interface variables. We argue that security mechanisms and control algorithms need to
be codesigned and comanaged with the embedded platform, so as to avoid the design of algorithms that are too expensive to implement on the embedded platform, or significantly impede
design objectives such as performance and timing robustness.

Abstract: This article is the first of a two-part series on the topic of visual servo control using computer vision data in the servo loop to control the motion of a robot. In the present article, we describe the basic techniques that are by now well established in the field. We first give a general overview of the formulation of the visual servo control problem. We then describe the two archetypal visual servo control schemes: image-based and position-based visual servo control. Finally, we discuss performance and stability issues that pertain to these two schemes, motivating the second article in the

Topic: A Wearable Robot for the Hand with a Soft Tendon Routing System

 

Abstract: oft wearable robots are good alternatives to rigid-frame exoskeletons because they are compact and lightweight. This article describes a soft wearable hand robot called the Exo-Glovemechanism. The proposed system can be used to develop other types of soft wearable robots. The glove part of the system is compact and weighs 194 g. The results that uses a soft tendon routing system and an underactuation adaptive
conducted using a healthy subject showed sufficient performance for the execution of daily life
activities, namely a pinch force of 20 N, a wrap grasp force of 40 N, and a maximum grasped
object size of 76 mm. The use of an underactuation mechanism enabled the grasping of
objects of various shapes without active control.

Topic: Task-Aware Interrupt Controller: Priority Space Unification in Real-Time Systems

 

Abstract; In the development of real-time systems, predictability is often hindered by technological factors which break the timing abstractions offered by real time operating systems
(RTOSs); namely, the priority space separation between threads and interrupts induces the rate-monotonic problem. Software approaches have tackled this issue, attempting to unify the priority
space with varying degrees of success. We present a hardware approach to the problem: unifying the priority space at the interrupt handling subsystem, predictability is greatly enhanced with minimum software modifications. Our solution provides the interrupt controller with awareness of the currently running
task’s priority making the solution independent of the used operating system. We show how our approach is minimally intrusive at hardware architecture level and provides benefits beyond the
capabilities of previous approaches. Our technique shows a 0.05% run-time overhead if no interrupts occur, and run-time reduction proportional to interrupt rate for rates higher than 5 per s, for a
interrupt workload around 0.07 ms.

Topic: Scheduling Dynamic Hard Real-Time Task Sets on Fully and Partially Reconfigurable Platforms

 

Abstract: Reconfigurable systems are increasingly being employed in a large class of today’s heterogeneous real-time embedded systems which often demand satisfaction of stringent timeliness constraints. However, executing a set of hard real-time applications on reconfigurable systems such that all timing
constraints are satisfied while also allowing efficient resource utilization requires effective scheduling, mapping and admission control strategies. This letter presents methodologies for scheduling periodic hard real-time dynamic task sets on fully and partially reconfigurable field-programmable gate arrays (FPGAs).
The floor of the FPGA is assumed to be statically equipartitioned into a set of homogeneous tiles (each of which act as individual processing elements or PEs) such that any arbitrary task of the given task set may be feasibly mapped into the area of a given tile. Experimental results reveal that the proposed algorithms are able
to achieve high resource utilization with low task rejection rates over a variety of simulation scenarios.

Topic: Exploiting Partially-Forgetful Memories for Approximate Computing

 

Abstract: While the memory subsystem is already a major contributor to energy consumption of embedded systems, the guard-banding required for masking the effects of ever increasing
manufacturing variations in memories imposes even more energy overhead. In this letter, we explore how Partially-Forgetful Memories can be used by exploiting the intrinsic tolerance of a vast class of applications to some level of error for relaxing this guard-banding in memories. We discuss the challenges to
be addressed and introduce Relaxed Cache as an exemplar to address these challenges for partially-forgetful SRAM caches. Preliminary results show how adapting guard-bands to application characteristics can help the system save significant amount of
cache leakage energy (up to 74%) while still generating
acceptable quality results.

Topic: Hibernus: Sustaining Computation During Intermittent Supply for Energy-Harvesting System

 

Abstract: A key challenge to the future of energy-harvesting systems is the discontinuous power supply that is often generated. We propose a new approach, Hibernus, which enables computation to be sustained during intermittent supply. The approach has a low energy and time overhead which is achieved by reactively
hibernating: saving system state only once, when power is about to be lost, and then sleeping until the supply recovers. We validate the approach experimentally on a processor with FRAM nonvolatile memory, allowing it to reactively hibernate using only energy stored in its decoupling capacitance. When compared to a recently proposed technique, the approach reduces processor time and energy overheads by 76%–100% and 49%–79% respectively.

Topic: A Security Layer for Smartphone-to-Vehicle Communication Over Bluetooth

 

Abstract: Modern vehicles are increasingly being interconnected with computer systems, which collect information both from vehicular sources and Internet services. Unfortunately, this creates a nonnegligible attack surface, which extends when vehicles are partly operated via smartphones. In this letter, a
hierarchically distributed control system architecture which integrates a smartphone with classical embedded systems is presented, and an ad-hoc, end-to-end security layer is designed to demonstrate how a smartphone can interact securely with a modern vehicle without requiring modifications to the existing in-vehicle
network. Experimental results demonstrate the effectiveness of the approach.

Topic: GSM CONTROLLED ROBOTICS

 

Abstract: In traditional methodology to find the motion of human we have some devices like video camera, radar, ultrasonic sensor etc. In case of video camera another human have to continuously monitor the video. If we use radar or ultrasonic sensor, we need a transmitter and a receiver. So these are high in cost and most of the jamming techniques are there to cheat (i.e. stealth bomber planes). But there is another interesting sensing device used to find the motion of human (i.e.) PIR (Pyroelectric Infra  Red sensor). It absorbs the infrared radiation (wave length of 9.4 micro meters) from the human body and creates a corresponding signal. As it has protection devices like lenses it is less suppose to be cheated. As this is sensitive only human body heat and frequency of radiation, this sensor can be used to find human upto 3 meter to 90 meter distance (using perfect Fresnel lenses). So it helps to find human availability beyond the barriers like walls and fire etc. It can be used as earth quake rescuer.

Topic: Autonomous Greenhouse Mobile Robot Driving Strategies From System Integration Perspective: Review and Application

 

Abstract: Agricultural operations are constantly becoming technology-driven mainly due to labor shortages, increase in labor cost, and trends in new and advanced technology applications. In this paper, we have presented a system-of-systems approach to design and development of a mobile robotic platform for agricultural applications. Similar to other field robots, the mobile platform for agricultural applications requires a different set of predefined attributes for its operation. We have designed, fabricated, and demonstrated the mobile platform for pesticide spraying application. The design and development includes synergistic integration of mechanical, sensor and actuator, navigational and control, and electronic and software interfacings. The autonomous navigation aspect of the development was achieved via three stages: learning stage, implementation stage (training stage), and testing stage. In the learning stage, we defined the path patterns and studied and recorded the behavior of the vehicle in real-world environment. In the training stage, various steering algorithms for four-wheel driving system were developed and inherent errors were compensated using advanced tools and methods. In the testing stage, we put the robotic platform on an arbitrary path pattern and demonstrated its success in autonomous navigation. The medium-sized mobile robot can be commercialized for greenhouse-based agricultural operations.

Topic: Autonomous Appliance Scheduling for Household Energy Management

 

Abstract: The advancement of renewable energy technologies has seen the emergence of customer owned grid tied wind and solar micro grids. These micro grids offer an opportunity to energy users to lower their energy costs as well as enabling the power suppliers to regulate the utility grid. However, the integration of the renewable energy based sources into the smart grid increases the complexity of the main grid. The success of this scheme will be heavily reliant on accurate real-time information exchange between the micro grid, the main grid, and the consumers. The communication between these agents will be critical in implementation of intelligent decisions by the smart grid. The micro grids will be required to relay energy forecasts information to the utility grid. Similarly, customers will be expected to submit energy demand schedules, to actively monitor energy price signals, to participate in energy bids, and to respond to energy management signals in real time. This kind of grid-user interaction will be overwhelming and could result in consumer apathy. There is therefore a need to develop smart systems that will autonomously execute all thesetasks without the prompting of the customers. This paper presents one such approach. In this study, we proposed a demand side energy management for a grid connected household with a locally generated photovoltaic energy. To ensure efficient household energy management, smart scheduling of electrical appliances has also been presented.

Topic: A Compact and Compliant External Pipe-Crawling Robot

 

Abstract: The focus of this paper is on the practical aspects of  design, prototyping, and testing of a compact, compliant external pipe-crawling robot that can inspect a closely spaced bundle of pipes in hazardous environments and areas that are inaccessible to humans. The robot consists of two radially deployable compliant ring actuators that are attached to each other along the longitudinal axis of the pipe by a bidirectional linear actuator. The robot imitates the motion of an inchworm. The novel aspect of the compliant ring actuator is a spring-steel compliant mechanism that converts circumferential motion to radial motion of its multiple gripping pads. Circumferential motion to ring actuators is provided by two shape memory alloy (SMA) wires that are guided by insulating rollers. The design of the compliant mechanism is derived from a radially deployable mechanism. A unique feature of the design is that the compliant mechanism provides the necessary kinematic function within the limited annular space around the pipe and serves as the bias spring for the SMA wires. The robot has a control circuit that sequentially activates the SMA wires and the linear actuator; it also controls the crawling speed. The robot has been fabricated, tested, and automated. Its crawling speed is about 45 mm/min, and the weight is about 150 g. It fits within an annular space of a radial span of 15 mm to crawl on a pipe of 60-mm outer diameter.

Topic: O-Track: Towards Order Tracking for Tags in Mobile RFID Systems

 

Abstract: In many logistics applications of RFID technology, luggage attached with tags are placed on moving conveyor belts for processing. It is important to figure out the order of goods on the belts so that further actions like sorting can be accurately taken on proper goods. Due to arbitrary goods placement or the irregularity of wireless signal propagation, neither of the order of tag identification nor the received signal strength provides sufficient evidence on their relative positions on the belts. In this study, we observe, from experiments, a critical region of reading rate when a tag gets close enough to a reader. This phenomenon, as well as other signal attributes, yields the stable indication of tag order. We establish a probabilistic model for recognizing the transient critical region and propose the OTrack protocol to continuously monitor the order of tags. To validate the protocol, we

evaluate the accuracy and effectiveness through a one-month experiment conducted through a working conveyor at BeijingCapital International Airport.

Topic: Portable Roadside Sensors for Vehicle Counting, Classification, and Speed Measurement

 

Abstract: This paper focuses on the development of a portable roadside magnetic sensor system for vehicle counting, classification, and speed measurement. The sensor system consists of wireless anisotropic magnetic devices that do not require to be embedded in the roadway—the devices are placed next to the roadway and measure traffic in the immediately adjacent lane. An algorithm based on a magnetic field model is proposed to make the system robust to the errors created by larger vehicles driving in the nonadjacent lane. These false calls cause an 8% error if uncorrected. The use of the proposed algorithm reduces this error to only 1%. Speed measurement is based on the calculation of the cross correlation between longitudinally spaced sensors. Fast computation of the cross correlation is enabled by using  frequency-domain signal processing techniques. An algorithm for automatically correcting for any small misalignment of the sensors is utilized. A high-accuracy differential Global Positioning System is used as a reference to measure vehicle speeds to evaluate the accuracy of the speed measurement from the new sensor system. The results show that the maximum error of the speed estimates is less than 2.5% over the entire range of 5–27 m/s (11–60 mi/h). Vehicle classification is done based on the magnetic length and an estimate of the average vertical magnetic height of the vehicle. Vehicle length is estimated from the product of occupancy and estimated speed. The average vertical magnetic height is estimated using two magnetic sensors that are vertically spaced by 0.25 m. Finally, it is shown that the sensor system can be used to reliably count the number of right turns at an intersection, with an accuracy of 95%. The developed sensor system is compact, portable, wireless, and inexpensive. Data are presented from a large number of vehicles on a regular busy urban road in the Twin Cities, MN,USA.

Topic: Receiver Autonomous Integrity Monitoring of GNSS Signals for Electronic Toll Collection

 

Abstract: Various road user charging mechanisms are used to control traffic and its resulting pollution, as well as revenue sources for reinvestment in the road infrastructure. Among them, electronic toll collection (ETC) systems based on user positions estimated with Global Navigation Satellite Systems (GNSS) are particularly attractive due to their flexibility and reduced roadside infrastructure in comparison to other systems such as tollbooths. Because GNSS positioning may be perturbed by different errors and failures, ETC systems, as liability critical applications, should monitor the integrity of GNSS signals in order to limit the use of faulty positions and the consequent charging errors. The integrity-monitoring systems have been originally designed for civil aviation; hence, they need to be adapted to the ETC requirements. This paper studies the use of receiver autonomous integrity monitoring (RAIM), which are algorithms run within the GNSS receiver and, therefore, are easier to tune to ETC needs than other systems based on external information. The weighted least squares residual RAIM used in civil aviation is analyzed, and an algorithm modification for ETC is proposed. Simulations demonstrate that the proposed RAIM algorithm has a superior level of availability over civil-aviation-based RAIM procedures, particularly in urban environments.

Topic: A Decentralized Cooperative Control Scheme with Obstacle Avoidance for a Team of Mobile Robots

 

Abstract: The problem of formation control of a team of mobile robots based on the virtual and behavioral structures is considered in this paper. In the virtual structure, each mobile robot is modeled by an electric charge. The mobile robots move toward a circle and due to repulsive forces between the identical charges, regular polygon formations of the mobile robots will be realized. For swarm formation, a virtual mobile robot is located at the center of the circle, and other mobile robots follow it. In the introduced approach, each mobile robot finds its position in the formation, autonomously, and the formation can change automatically in the case of change in the number of the mobile robots. This paper also proposes a technique for avoiding obstacles based on the behavioral structure. In this technique, when a mobile robot gets close to an obstacle, while moving toward its target, a rotational potential field is applied to lead the mobile robot to avoid the obstacle, without locating in local minima positions.

Topic: Circuit Design and Power Consumption Analysis of Wireless Gas Sensor Nodes: One-Sensor Versus Two-Sensor Approach

 

Abstract: Wireless sensor networks (WSNs) have recently been applied in industrial monitoring applications including hazardous gases detection. As a major power consumer of a node, gas sensors may significantly constrain its lifetime. Hence, the sensing circuit must be carefully designed to optimize

performance and retain accuracy. In this paper, we propose for the first time the principle of gas concentration measurement based on a single sensor in a voltage divider circuit, instead of the well-known Wheatstone bridge sensing circuit, which employs two sensors. We discuss the design of a real WSN node for gas sensing and evaluate it with respect to an identical platform that uses the Wheatstone bridge. The proposed approach ensures significant energy savings and helps to avoid zero offset issue. Besides, we employ a more efficient and secure sensor heating profile; it does not damage the sensor and does not make gas sensing dependent on environmental conditions. Experimental results show a 30% reduction in power with respect to the state-of-the-art.

Abstract: The mining industry employs more than three million people and exports more than US$26 billion worth of minerals and related materials each year. RFID offers numerous advantages for mining and related industries, where hostile environments make it desirable to track personnel closely for safety reasons (for more information on RFID, see the sidebar). RFID can also help manage and control a fleet of mine vehicles, which is especially beneficial given the increased use of remotely directed units. Close control of hazardous materials, such as explosives and detonators, is also critical in mining operations, presenting new opportunities for RFID.

Topic: Modeling and Detecting Aggressiveness From Driving Signals

 

Abstract: The development of advanced driver assistance systems (ADASs) will be a crucial element in the construction of future intelligent transportation systems with the objective of reducing the number of traffic accidents and their subsequent fatalities. Specifically, driving behaviors could be monitored online to determine the crash risk and provide warning information to the driver via their ADAS. In this paper, we focus on aggressiveness as one of the potential causes of traffic accidents. We demonstrate that aggressiveness can be detected by monitoring external driving signals such as lateral and longitudinal accelerations and speed. We model aggressiveness as a linear filter operating on these signals, thus scaling their probability distribution functions and modifying their mean value, standard deviation, and dynamic range. Next, we proceed to validate this model via an experiment, conducted under real driving conditions, involving ten different drivers, traveling a route with five different types of road sections, subject to both smooth and aggressive behaviors. The obtained results confirm the validity of the model of aggressiveness. In addition, they show the generality of this model and its applicability to specific driving signals (speed, longitudinal, and lateral accelerations), every single driver, and every road type. Finally, we build a classifier capable of detecting aggressive behavior from the driving signal. This classifier achieves a success rate up to 92%.

Topic: Performance of Drivable Path Detection System of Autonomous Robots in Rain and snow Scenario

 

Abstract: Drivable path detection is an important factor to consider for a successful development of autonomous robot which is characterized as an intelligent vehicle. Researchers using different vision-based techniques have achieved remarkable result toward drivable path detection. Regardless of this achievement, environmental noise such as rain and/or snow can cause misdetection of drivable path which can lead to autonomous robot accident. In this paper, after investigating the effects of rain and/or snow, we introduced into the drivable path detection system a filtering algorithm that addresses the detection and removal of rain and/or snow for the optimization of the system. Experiments were carried out to show the effectiveness of the filter in the system. The results show that filtering algorithm assists the autonomous driving system in navigating perfectly during rain and/or snow scenario with minimal accident.

Topic: Motion Planning of Multi-docking System for Intelligent Mobile Robots

 

Abstract : The article develops a multi-docking system with a mobile robot and three docking stations. The docking structure is designed with one active degree of freedom and two passive degrees of freedom. The controller of the power detection devices is HOLTEK microchip, and acquires measurement values of the real-time current and voltage of the mobile robot and the docking stations. The power detection devices contain three power detection systems and one power detection module. The power detection system is embedded in the docking station and monitors the real-time information for the charging process. The controller of the mobile robot receives these measurement values from the power detection module via RS232 interface. The article focuses on the searching process using multiple sensors and a laser range finder for the mobile robot. The laser range finder searches the landmark of each docking station, and guides the mobile robot moving to the assigned docking station. In the experimental results, the power of the mobile robot is under the threshold value. The mobile robot selects the free and nearest docking station according to the received information from each docking station via wireless RF interfaces. The laser range finder guides the mobile robot moving approach to the assigned docking station. The power of the mobile robot is enough to be detected by the power detection module. The docking station turns off the charging current, and trigs the mobile robot leaving the docking station via wireless RF interface.

Abstract: Operations  like  radioactive  waste  handling,  bomb disposal,  surveillance,  search  and  rescue  are  today  performed mostly  by  humans  at  great  risk  to  their  own  safety  and  wellbeing.  In  order  to  minimize  direct  human  intervention  in  such operations,  the  design  of  a  remotely  operated  versatile Unmanned  Ground  Vehicle  (UGV)  mounted  with  a  robotic manipulator  is  presented  in  this  paper.  The  robustness,  range and security of the communication link between the remote base station  and  the  robot,  obstacle  avoidance  and  the  real  time control  of  the  robot  are  some  of  the  major  issues  encountered while deploying such robots in the above scenarios. In this paper, the  design  of  a  versatile  UGV  which  leverages  the  already existing  GSM  mobile  telephony  network  to  establish  a  longrange, secure, fast and reliable connection with the remote base station  is  presented.  The  UGV  is  also  mounted  with  a  robotic manipulator  with  four  degrees  of  freedom  with  a  gripper  type end-effector,  which  can  be  used  for  grabbing  objects  and  thus help in search and rescue type operations. The robot is equipped with IR sensors and camera for obstacle detection and avoidance. The  camera  is  also  used  to  send the  visual information  back  to the  base  station  in  real-time,  allowing  accurate  control  of  and monitoring over long distances.

Topic: Design  of  an  Intelligent  Security  Robot  for Collision  Free  Navigation Applications

 

Abstract: Robotics  industry  has  replaced  human  efforts gradually  in  performing  rather  difficult tasks. A very  pertinent aspect of an intelligent security robot is to reach  the  goal safely by avoiding  unknown  obstacles  in  an unknown  environment.  In  this paper we have  developed an embedded C  program code  to design an intelligent robot which can  overcome the obstacles  coming in  its way.  We  have  made  use  of  three  infrared  sensors  to  detect  the obstacles via the IR communication technique. The IR transmitter sends  out  infrared  radiation  in  a  direction  which  consequently bounces  back  on  coming  across  the  surface  of  an  object  and thereafter  is  picked up by  the  IR receiver.  Authors have  applied a multi sensor  integration  technique  to  sense  the  obstacles using  an LED based IR  transmitter and  receiver module integrated with the 8051  micro controller which  permits  collision  free  navigation  of robots.

Topic: PROTOTYPE OF A FINGERPRINT BASED LICENSING SYSTEM

FOR DRIVING

 

Abstract: To prevent non-licensees from driving and therefore causing accidents, a new system is proposed. An important and very reliable human identification method is fingerprint identification. Fingerprint identification is one of the most popular and reliable personal biometric identification methods. The proposed system consists of a smart card capable of storing the fingerprint of particular person. While issuing the license, the specific person’s fingerprint is to be stored in the card. Vehicles such as cars, bikes etc should have a card reader capable of reading the particular license. The same automobile should have the facility of fingerprint reader device. A person, who wishes to drive the vehicle, should insert the card (license) in the vehicle and then swipe his/her finger. If the finger print stored in the card and fingerprint swiped in the device matches, he/she can proceed for ignition, otherwise ignition will not work. Moreover, the seat belt detector verifies and then prompts the user to wear the seat belt before driving. This increases the security of vehicles and also ensures safe driving by preventing accidents.

Topic: A Novel Design For Vehicle License Plate Detection and Recognition

 

Abstract: License plate recognition (LPR) plays a major role in this  busy  world,  as  the  number  of  vehicles  increases  day  by  day, theft of vehicles, breaking traffic rules, entering restricted area are also increases linearly, so to block this act license plate recognition system  is  designed.  License  Plate  Recognition  systems  basically consist  of  3  main  processing  steps  such  as:  Detection  of  number plate,  Segmentation  of  plate  characters  and  Recognition  of  each character.  Among  this,  character  segmentation  is  a  most challenging task, as the accuracy of the character recognition relies on  the  accuracy  of  the  character  segmentation.  Problems of different lighting  condition,  adhesion,  fracture,  rivet,  rotation degrades the accuracy of the character segmentation. So in order to come these  problems  and  uplift  the  accuracy  of  character segmentation various algorithms are developed for this work. This thesis  presents  a  robust  method  of  license  plate  location, segmentation  and  reorganization  of  the  characters  present  in  the located  plate.  The  images  of  various  vehicles  have  been  acquired and  converted  in  to  gray-scale  images.  Then  noise  present  in  the plates  are  removed  and  the  segmentation  of  gray  scale  image generated by finding edges for smoothing image is used to reduce the number of connected component and then bw label is used to calculate the connected component. Finally, single character in the license  plate  is  detected.  The  aim  is  to  show  that  the  proposed method achieved high accuracy by optimizing various parameters  with higher recognition rate than the traditional methods.

Topic: Vision-Based Path Planning with Obstacle Avoidance for Mobile Robots using Linear Matrix Inequalities

 

Abstract: In this paper, a vision-based obstacle avoiding path generation problem is considered for autonomous mobile robots under a top-view workspace. The collision-free path planning problem is converted to a convex optimization problem that can be solved numerically using linear matrix inequalities (LMI). A new optimal (shortest) path cost formulation is given for LMI optimization using a novel Line of Sight Meshing (LSM) method. As compared to the traditional meshing algorithms such as Voronoi and Delaunay, the LSM generates fewer mesh cells which results in reduced computation time. A virtual path diagram (VPD), consisting of all collision-free piecewise straight line paths, is then found for robot navigation. The LMI optimization method is then used to find the optimal (shortest) collision-free path from the VPD set. In addition to distance, other constraints, such as terrain condition and curvature of the path can be incorporated in the cost function for constrained optimal solution. Finally, a rapid prototyping (RP) environment has been developed, which is used for hardware implementation of the algorithm. The generated paths are then converted to motion commands, which are sent wirelessly from a base-station to mobile robots for motion control.

Topic: DEVELOPMENT OF A ROBOTIC ARM FOR DANGEROUS OBJECT

DISPOSAL

 

Abstract: The Boko Haram insurgency in Nigeria has become menace and threat to the security of lives and property most especially in the Northern part of the country. The use of Bombs and dangerous unsuspected objects is the weapon employed to carry out this deadly act. The number of lives lost as well as personnel who sustain injuries while discharging their duties is now on the increase as a result of lack of initial assessment of a dreadful scene or an object suspected to be harmful. Though preventive and counter attacking measures, such as use of protective vest have been employed to reduce the risk experienced; these however do not guarantee safety which can run into huge cost to restore in terms of infrastructures and properties. Hence this paper proposes the development of a robotic arm for dangerous object disposal. A three-degree of freedom robotic arm was developed using a microcontroller programmed with (MPLAB) integrated development environment software, interfaced to a camera that transmits the video by way of monitoring the scene on a television set. The system is activated by a remote control thereby providing a line of defense to human lives and preventing loss of proven and tested personnel.

Topic: HEART RATE MONITOR

Abstract: Heart rate can be measured either by the ECG waveform or by the blood flow into  the  finger  (pulse  method).  The  pulse  method  is  simple  and convenient. When blood flows during the systolic stroke of the heart into the  body  parts,  the  finger  gets  its  blood  via  the  radial  artery  on  the  arm. The blood flow into the finger can be sensed photo electrically. To count the heart beats, here  we use a small light source on one side of the finger (thumb)  and  observe  the  change  in  light  intensity  on  the  other  side.  The blood flow causes variation in light intensity reaching the light dependent resistor (LDR), which results in change in signal strength due to change in the resistance of the LDR.’

Topic: INTELLIGENT TRAFFIC LIGHT SYSTEM

 

Abstract: Traffic light intervals are fixed independent of traffic movement. So sometimes large red light  delay  cause  traffic  congestion.  Here  is  a microcontroller  based  intelligent  traffic  light  system  that  reduces  the possibility  of  traffic  jams  caused  by  traffic  light  delays  to  an extent.

Microcontroller counts the number of vehicles passing the road. Based on the  vehicle  count,  the  system  has  three  traffic  profiles-low,  medium  and high.  The system contains different traffic light intervals (red, yellow, and green  light  delays  in  seconds)  for  different  traffic  profiles.  After

calculating  the  traffic  profiles ,  Depending  on  the  number  of  vehicles passing trough the IR system in a predefined controlling interval (e.g. one minute).  It further controls the timing of traffic Lights.  After  the controlling  interval  lapses,  the  vehicle  count  is  reinitialized  to  zero  to calculate  the  traffic  profile  again  in  the  next  controlling  interval.  The lcd  Display  current  profile  delay  (RED,  YELLOW,  GREEN),  current profile  (LOW,  MID,  HIGH),  running  time  of  the  system

(HH:MM:SS),  and also display how Many vehicles were passed (VEH:05 ) and so on.

Topic: PROGRAMMABLE INDUSTRIAL ON-OFF TIMER WITH RF REMOTE

 

Abstract: In  most  of  the  modern  manufacturing  and  processing  industries, there is complete industrial automation through sophisticate hardware and software  like  programmable  logic  controller  (PLC),  distributed  control system  (DCS),  and supervisory control  and  data  acquisition  (SCADA).

Microcontroller-based  embedded  systems  play  major  role  in  industrial automation. One such widely used  system is the programmable timer. The major applications of programmable timer are as follows: 1.  initiating  the process  after  desired  time.  2.  Switching  on/  off  the  process  after

predetermined  time  3.  Providing  delay  in  between  processes  4.  Applying input  to  on/off  type  open-loop  control  system  depending  upon  the requirement of process, one can set the time of programmable timer. As the time period expires, the timer will either trigger 01’shut the process. Earlier

there were mechanical timers that used gear assembly (same as wall clock) and  mechanical  contacts.  But  the  problem  with  these  was  that  due  to mechanical parts and movements, they were not durable. Electronic timers have  become  very  popular  as  these  have  more  functionalities  and  long

operating  life.  A  simple  electronic  timer  can  be  to  enhance the programmable timer for generating precise timing and additional features, micro controllers (embedded controllers) are used with peripheral devices. Some  of  the  features  of  programmable  industrial  on/  off  timer  presented

here  include:  1.  Time  set  from 1 to  60  seconds  (canbe  extended)  2..  ‘On’ time  and’  off’  time  can  beprogrammed  (from 1 to  60  seconds  3.  Repeat (continuous)  and  single  operation  4.  Fully  remote-controlled  within  100-metre range    5. User-friendly front-panel controls and display panel with LCD 6. Emergency stop buttons (on control panel as well as on remote)    7. Provision  of  potential-free  relay  contacts  for  connecting  any  230VAC  at lOA or 28V DC at lOA device/ application

Topic: WATER LEVEL TANK CONTROLLER (UNDER AND OVER TANK FLOW CONTORL)

 

Abstract: When water in the tank is below sensor A, the motor will switch on to fill water in the tank. The LCD module will show ‘motor on.’ The controller is programmer for a 10- minute time interval to check the dry-run condition of  the  motor.  If  water  reaches  sensor  B  within  10  minutes,  the  micro

controller comes out of the dry-run condition and  allows the motor to keep pushing  water  in the tank. The  motor will remain  ‘on’  until water reaches sensor  C.  Then it  will stop  automatically  and  the  microcontroller  will  go into the standby mode. The LCD module will II show ‘tank full’ followed

by  ‘standby  mode’  after  a  few  seconds.  The  ‘standby  mode’  message  is displayed until water and if the dry-run condition still persists, the display will  show’  drysump3′  and  the  micro  controller  will  not  start  the  motor automatically.  Now  you  have  to  check  the  line  for  water  and  manually

reset  the  microcontroller  to  start  operation.  In the whole procedure, the micro controller checks for high and low voltages. For example, when the voltage is high, it will scan for about two seconds to check whether it is a fluctuation.  If  the  voltage  remains  high  after  two  seconds,  the microcontroller will  halt  running  of  the  motor.  Now it will wait for the voltage to settle down. After the voltage becomes normal, it will still check for 90 seconds whether the voltage  is  normal  or  not.  After  normal condition,  it  will  go  in  the  standby  mode  and  start  the  aforementioned procedure.

Topic: RF AND INFRA RED FREQUENCY BASED MOBILE LAND ROVER

 

Abstract: We  present here is an elementary robotic land rover that can be controlled remotely  using  primarily  the  RF  mode.  The  RF  remote  control  has  the advantage  of  adequate  range  (up  to  200  metres  with  proper  antennae) besides  being  omni  directional.  On  the  other  hand,  an  IR  remote  would function over a limited range of about 5 metres and the remote transmitter has  to  be  oriented  towards  the  receiver  module  quite  precisely.  Cost involved in using RF modules is much higher than of IR components and as such, we have included the replacement alternative of RF modules with

their  IR  counterparts  for  using  the  IR  remote  control.  The  proposed  land rover can move in forward and reverse directions. You would also be able to  steer  it  towards  left  and  right  directions.   FORWARD,  REVERSE, LEFT, RIGHT, STOP CONTROLLED BY RF/INFRA RED.

Topic: PC BASE WIRELESS APPLICANCE CONTROL

 

Abstract: The  parallel  port  of  the  PC  is  a  powerful  platform  for  implementing projects dealing with the control of real-world peripherals. It can be used to control home and other electronic appliances.  The  computer  program through the interface circuit controls the relays, which, in turn, switch the appliances’  on’  or  ‘off.’  Here  we  describe  how  to  wirelessly  control electronic appliances from a remote place by using the RF module. For this PC-based  wireless  appliances  control  system,  you  need  to  design  and develop .the required hardware and software. The parallel port of the PC is used to control the appliances at the transmitter side. The RF  interface is used instead of the IR to overcome all the drawbacks of the IR interface. The PC signals are transmitted from the RF transmitter and received by the RF receiver.

Topic: MICRO CONTROLLER BASED ONE DC MOTOR CONTROLLER

 

Abstract: Dc  motor  speed  controllers are  very  useful  for  controlling  the motion  of  robotic  and  industrial  automation  systems.  The controller presented here uses the pulse-width modulation  (PWM) technique.  The PWM  wave  for  speed  control  is  generated  using  Atmel  AT89C52 microcontroller. To control the speed of the DC motor, you need a variable -voltage  DC  power  source.  When  the  DC  motor  is  switched  on,  it  takes certain  time  to  reach  the  full  speed.  As  soon  as  the  power  supply  is switched on, the DC motor starts gaining speed and if you switch off the

power supply before it reaches the maximum rated speed, it starts to slow down. In case switching on and switching off are done in quick succession, the motor rotates at a slower speed between zero and full rated speed. This is what a PWM technique based controller does: it switches the motor’ on’ and  ‘off’  with a  pulse  train.  To  control  the  motor  speed,  it  varies (modulates)  the  width  of  the  pulses-hence  the  pulse  width  modulation. When the  motor  is, on‟  for a short period and  ‘off’  for a  long one,  it will rotate slowly. When the motor is ‘on’ for most of the time and’ off’ only for a short while, it will rotate at higher speed, say, nearly at full (maximum) rated speed.

Topic: MOVING MESSAGE DISPLAY USING ALPHA NUMERIC DISPLAY

 

Abstract: LED-based  moving- message  displays  are  becoming  popular  for transmitting  information  to  large  groups  of  people  quickly.  These  can  be used indoors or outdoors. We can find such displays in areas like railway platforms, banks, public offices, hotels, training  institutes, nightclubs and shops.  Compared  to  LEDs,  liquid-crystal  displays  (LCDs)  are  easy  to interface  with  a  microcontroller  for  displaying  information  as  these  have many  built-in  functions.  But  these  can’t  be  observed  from  a  distance  and large size LCDs are very costly. LED-based displays can be of two types: dot-matrix  and  segmental.  If  you  implement  a  moving- message  display with multiplexed dot- matrix LEDs, it will be very costly for displaying 16 characters or more at a time.
