SPY Night Vision Robot with Moving Wireless Video Camera & Ultrasonic Sensor

It is unique spy robot circuit which can be controlled by using a computer system from its keyboard. It can act as a live telecast of audio and video information’s from the surroundings and can be sent to a remote station through RF signals & also able to access information when surrounding have darkness because its include extra circuitry arrangement which detect darkness and automatically switch on its flash light. Moment of camera is also possible just by specific key command from the keyboard. The maximum range is 200 meters. Another feature included it measure the distance of object at front of robot and also automatically stop robot if its detect distance of object is inside 10cm & data of distance can be also access at remote section unit by send RF signal. It overcomes the limited range of infrared remote controllers. The circuit uses RF modulator, two RF modulator is used it is Trans receiver. So RF 2.4GHz ASK transmitter and receiver are used for the remote control which provide serially communication under specific range. H-bridge circuits are used for driving motors of base & relay board is used for drive motor of camera arm moment. Two 12V DC/60RPM gear motors are used as drivers & Two 12V DC/10RPM gear motors are used as camera arm. In this paper we are using a wireless video camera. It works on 12VDC supply. The 12 Volt DC supply is taken from the battery placed on the robot. The camera has a receiver, which is placed in the remote station. Its output signals are in the form of audio and video. These signals are directly connected to a TV receiver or a computer through a tuner card.
