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 Le arned 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.

EMB_2015_03 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 mont hs. 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

2015

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.

EMB_2015_06 Topic: Design and O peration 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.

Topic: Visual Servo Control Part I: Basic Approaches 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 series, in which we consider advanced techniques.

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-Glove mechanism. 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 t ime 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.

EMB_2015_11 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 t iming

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.

EMB_2015_13 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 O ver 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 RO BOTICS 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: Passenger BUS Alert System for Easy Navigation of Blind Abstract: Talking signs, guide cane, echolocations are all useful in navigating the visually challenged people to reach their destination, but the main objective is not reached that it fails to join them with traffic. In this project we propose a bus system using wireless sensor networks (WSNs).The blind people in the bus station is provided with a ZigBee unit which is recognized by the ZigBee in the bus and the

indication is made in the bus that the blind people is present in the station. So the bus stops at the particular station. The desired bus that the blind want to take is notified to him with the help of speech recognition system HM2007. The blind gives the input about the place he has to reach using

microphones and the voice recognition system recognizes it .The input is then analyzed by the microcontroller which generates the bus numbers corresponding to the location provided by the blind. These bus numbers are converted into audio output using the voice synthesizer APR 9600. The ZigBee transceiver in the bus sends the bus number to the transceiver with the blind and the bus number is

announced to the blind through the headphones. The blind takes the right bus parked in front of him and when the destination is reached it is announced by means of the GPS-634R which is connected with the controller and voice synthesizer which produces the audio output. This project is also aimed at helping the elder people for independent navigation.

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 t ime. 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 t o 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.

NEXGEN TECHNOLOGY




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 t ime 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

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 t raffic 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

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.

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: PRO TOTYPE O F A FINGERPRINT BASED LICENSING SYSTEM

FO R 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.

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.

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: WATER LEVEL TANK CO NTRO LLER (UNDER AND O VER TANK FLO W CO NTO RL) 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 t he 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.

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 t ime 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: WIRELESS MICRO CO NTRO LLER BASED AUTO MATIC FLUSH SYSTEM

Abstract: In manual flush system the user press a button, which opens a flush valve allowing mains-pressure water to flow into the bowl, or sometimes the user press directly a flush lever (a handle connected to a flush

meter). The value contains a pneumatic mechanism that closes it after a reset t ime. Today, manual flush system has been replaced with a sensor operated system that automatically flushes the fixture when the user departs. The microcontroller based automatic flush system is infrared sensor to detect a user approaching the fixture, then it wait until the user departs. It also

flushes before the person departs if the person is person for more than the preset time (5 minutes) .

Topic: MO VING 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.
