The servo motor is used to rotate wheels of robot car. Using Arduino we implement the logic of move car in directions like forward, backward, right and left

Review on robot following human using body area structure to detect the innominate miscellaneous

In the fast growing world the technology got improved by the machine equipment. It can do all the activities which humans can do. This robot follows the human’s full structure. It can be used in military, medical etc. The robot can be safeguard for the humans in the defense field. In proposed system the robot follows the human and protects the border security of the nations from the attack. Before implementing the systems the research is undergoes about the human to human communication how the message is get transfer and the performance according to that. The signal from the human is received by the robot by the use of ultrasonic sensor. The robots can response according to the sensor signal. When the signal is received the activities of the robot is fully controlled by the human. The metal detector sensor is placed within the robot. These robot can moves around the border signal when it detects the under placed bomb it transmit the signal and gives the alter to them. The signals are transmitting in the area of network the signal can be transmit to the better distance. We have done the design simulation using proteus software and shows the interaction of the signal between the robots and the humans.

Characterization of Electromagnetic Properties of In Situ Soils for the Design of Landmine Detection Sensors: Application in Donbass, Ukraine

To design holographic and impulse ground penetrating radar (GPR) sensors suitable for humanitarian de-mining in the Donbass (Ukraine) conflict zone, we measured critical electromagnetic parameters of typical local soils using simple methods that could be adapted to any geologic setting. Measurements were recorded along six profiles, each crossing at least two mapped soil types. The parameters selected to evaluate GPR and metal detector sensor performance were magnetic permeability, electrical conductivity, and dielectric permittivity. Magnetic permeability measurements indicated that local soils would be conducive to metal detector performance. Electrical conductivity measurements indicated that local soils would be medium to high loss materials for GPR. Calculation of the expected attenuation as a function of signal frequency suggested that 1 GHz may have optimized the trade-off between resolution and penetration and matched the impulse GPR system power budget. Dielectric permittivity was measured using both time domain reflectometry and impulse GPR. For the latter, a calibration procedure based on an in-situ measurement of reflection coefficient was proposed and the data were analyzed to show that soil conditions were suitable for the reliable use of impulse GPR. A distinct difference between the results of these two suggested a dry (low dielectric) soil surface, grading downward into more moist (higher dielectric) soils. This gradation may provide a matching layer to reduce ground surface reflections that often obscure shallow subsurface targets. In addition, the relatively high dielectric deeper (10 cm–20 cm) subsurface soils should provide a strong contrast with plastic-cased mines.

RF Controlled Metal and Deleterious Gas Detecting Rover

Many advance technologies have undergone for the space missions and also geographical locations in space. Earlier humans had to move manually to space for the research but it was risky and resulting in loss of life. Hence in present and the future technology everything is operated and controlled through robots, this device deals with the rover which can move anywhere in the space surface. This rover is built with ARM controller interfaced with Gas and Metal detector sensor. This Rover also contains Zigbee module to transmit the result obtained to the receiver section and it displays the result on LCD. It is operated through RF controlled remote for making the checkpoint as per the user commands.

Development of Autonomous Self-Powered Robotic System for Antipersonnel Landmines Detection and Extraction

Detection and removal of antipersonnel landmines has become one of major scientific and technological challenges. Conventional methods of demining are expensive, slow and low efficiency. There is a dire need for automated, efficient, lowcost, and self powered robotic systems for the purpose of mine detection and disposal. This paper deals with the design and development of a novel low cost robotic system for mine detection and extraction. This robotic system consists of a mobile platform carrying flexible arm, the sensors system and the developed electronic cards of the system. The sensors system comprises an efficient design of metal detector sensor in addition to a distributed sensors fusion system that identifies the robot environment and operation. The robot extracts the mine by drilling the soil around the mine without touching it, catching the mine and extracting it from the ground while enabling the operator to control the robot wirelessly from a safe distance. A renewable solar power supply is supplemented to provide the system with the necessary power. Control of the overall system is achieved using PICs 18F452 microcontroller circuits. A prototype is developed and extensive field tests were performed that confirms the success of the illustrated design.

The robotic vehicle is controlled using android application for metal detection operation controlled with the help of Bluetooth technology. This project can be widely used because of its simplicity and ability to modify to meet changes of needs. Based on experimental studies, it was found that the mobile controlled robot can move in any direction as per the desired instruction and the beeper in the metal detector circuit beeps whenever it encounters any metallic object.

G-Quadruplexes Light up Localized DNA Circuits.

DNA circuits tethered to nanoplatforms can perform cascade reactions for signal amplification. One DNA single strand activates a strand-displacement cascade generating numerous outputs, and therefore amplifying the signal. These localized circuits present, however, an important limitation: the spontaneous activation of the cascade reaction. Current methods to stabilize these circuits employ combination of protective DNA strands, which need to be removed to activate the device. This protection-deprotection process generates an important amount of unwanted side reactions. This is indeed an important limitation for the large potential application of these amplification circuits. In the present work, G-quadruplex DNA structures were used to stabilize localized DNA circuits. This new protocol generates nanoplatforms that no longer requires protective-deprotective systems and is therefore completely neutral to the sample. In addition, cations such as Pb(2+) or Ca(2+) can be also employed to activate the device enlarging the potential applications from biosensors devices to metal detector sensors.

In this paper, analysis of the vibration characteristic for the mine detectable test platform is described. The test platform system is the multi-sensor mine detectable vehicle. This multi-sensor mine detectable unit is more efficient detection performance than other conventional methods. The test platform system has five subsystems, the UWB(ultra wide band) sensor scanner, the MD(metal detector) sensor scanner, the ND(neutron detector) sensor scanner, and the detectable vehicle. We perform the vibration tests for the test platform and analyze the vibration characteristic, such as the max displacement, the max deformation and the max Von-Misses stress.

Land Mine and Clutter Object Discrimination Using Wavelet and Time Domain Spatially Distributed Features from Metal Detectors and Their Fusion with GPR Features for Hand-Held Units

This paper presents some advances in discrimination and fusion algorithms using metal detector (MD) and ground penetrating radar (GPR) sensors in a robotic wand unit. Previously investigated spatially distributed features are extended and fused with discrete wavelet transform representations of MD data. A multilayer perceptron technique is then applied to discriminate between land mine and land mine-like objects based on the wavelet coefficient and time domain features separately. Using MD wavelet and time domain fusion, the probability of false alarms is reduced by 46.0% and 18.0% over the wavelet and time domain models, respectively, at 0.95 probability of detection. Fusion results are presented for the MD and GPR sensors to demonstrate that the two sensors provide complementary information for significantly reducing the probability of false alarm. Blind test results from a government test facility are presented to evaluate the effectiveness of the algorithms.
