Abstract: This paper presents an application of bomb diffusion. This robot moves in four directions like forward, backward, right and left. Here the robot receives the signal from color sensor and then move accordingly. The signal received by robot is in the form of light. This robot contains a camera at the receiver end. The display of the view captured by the camera is on transmitter end which contains LCD. The main application of this robot is to diffuse the metallic bombs which are placed inside the digs and the places where human canít reach. A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm.
