Metal Detector Robotic Vehicle

Abstract

The metal detector robot is used to search for metals under the ground , this is useful for metal detection in places where human being can’t reach easily Here in this project An automatic robot was designed , which is capable of detecting metal and taking from their locations, The robot will travel in a straight line path , tow DC geared motor ( 24 V, 2 A ) are used for controlling the movement of robot , h-bridge also used in this robot to control the direction of DC motors , pulse with modulation ( PWM) can be control the speed of motor through changing the input frequency on PWM . We used Ultrasonic Sensors automatically senses the presence of a obstacle in its path and deviates its path or stops its journey. The obstacle detection mechanism is managed by a ultrasonic sensor which makes uses of ultrasonic waves to find theك8 presence of a obstacle in its path. Metal detector circuit is designed to detect metals, if there is metal robot beeps and stop motion .
