The present invention provides a simple and relatively low cost way of performing a metal or bomb detection test on the test system to determine whether or not the system is subject to bomb explosion. The metal detector will be fixed in the predetermined area to check the possibility of a metal or a bomb. If there is an existence of metal in that area, the metal detector identifies the metal and intimates this to the controlling unit. Since the human cannot enter into the area where there the bomb or metal is present, a Robot is employed to move in the simulated environment and continuously monitor the status of the metal detector in that particular area.

The system is entirely an automated design. The microcontroller plays a vital role in this project. The controlling section will be fixed to the robot. The controlling contains the microcontroller, metal detector and the buzzer circuit. 

The microcontroller continuously monitors the output of the metal detector. If any metal is found, the metal detector recognizes it and its output changes immediately. The microcontroller detects this and immediately alerts the buzzer.
