The intention of this paper is to reduce human victims in terrorist attack. So this problem can be overcome by designing the RF based spy robot which involves wireless camera. So that from this we can ex-amine rivals when it required. This robot can quietly enter into enemy area and sends us the information via wireless camera. On the other hand one more feature is added in this robot that is color sensor. Color sensor senses the color of surface and according to that robot will change its color. Because of this feature this robot can’t easily detected by enemies. The movement of this robot is wirelessly controlled by a hand held RF transmitter to send commands to the RF receiver mounted on the moving robot
