DTMF Based Bomb Detection with Collision Avoidance Robot

Abstract

Here we presents the wireless bomb detection robot which will help to improve defense of our nation .The bomb detectors system works only with the presence of experts. But this way of analyzing takes more time and make risk to life of experts. This uses wireless technology for controlling action. The aim of our project is to design a wireless robot for bomb surveillance and detection with a metal detector. This robot can be moved in Omni-direction using geared motors of 100RPM. Also we are interfacing the Obstacle Sensor which avoid collision of the robot with any obstacle in its track when it will be sensing metal body within its range for bomb detection.LCD is use to display all directions along with obstacle sensed and Metal Detected. The robot is controlled by remote control. Wireless control of robot is achieved using DTMF code signals.Micro-controllerPIC18F4520 has been used to control the direction of robot. The motor driver circuit has been used to provide reversible drive to the dc motors.
