Abstract: System is designed to detect the projectile (missile) moving in multiple directions. The robotic demolish system moves automatically in direction of the missile and fires it upon fixing the target. An ultrasonic module interfaced to a microcontroller of 8051 family is used in this system. An ultrasonic transducer comprising of transmitter and receiver are used. Transmitted waves are reflected back and received by the transducer. By taking into consideration the velocity of sound, the total time taken from sending waves till it is received is calculated. The distance is measured by the program on the microcontroller and displayed on LCD screen interfaced to the microcontroller through Zigbee wireless communication. The circuit will receive the reflected signals of 40KHz from the missile object, and it is fed to a program of microcontroller. As soon as the microcontroller gets the signal from the ultrasonic receiver it activates the door gun by triggering the gate of MOSFET through the transistor or relay. The sensor is rotated and controlled by stepper motor through 360 degrees. In case if there is any target within the detection range the application will turn the launcher to the nearest detected target and fires.
