This is one of the version of spy robot which we designed in this academic period. Intelligent spy robot project has been designed for the spying purpose .it is radio controlled and can be operated at a radial distance of 50 yards. Many time our army jawan need to venture into the enemy area just to track their activities. Which is often a very risky job, it may cost precious life. Such dangerous job could be done using small spy robot all the developed and advance nations are in the process of making combat robot design, a robot who can fight against enemy. Our robot us just a step towards similar activity. This robot is radio operated , self powered , and has all the controls like a normal car. A laser gun has been installed on it so that it can fire on enemy remotely when required, this is not possible until a wireless camera is installed. Wireless camera will send real time video and audio signals which could be seen on a remote monitor and action can be taken accordingly. Being in size small will not be tracked by enemy on his radar. It can silently enter into enemy canopy or tent and send us all the information through its’ tiny camera eyes. It can also be used for suicide attack, if required.

Transmitter circuit explanation:
six keys are connected in four by two matrix to the microcontroller ic1 at2051.Key data is transmitted through the 433mhztransmitter module through its pin no 3 of the microcontroller which is tx pin of the inbuilt UART of the microcontroller and works on 1200bits/sec. X1 gives the required clock input to the microcontroller c1 and r1 forms the reset circuitory connected to pin no 1 of the microcontroller. Key pressed value is transmitted through antenna Construction:

Solder all the parts provided in the kit properly. First connect the jumper wires(links) before you solder the IC sockets. Donot solder integrated circuits directly on the circuit board, it may damage the ic since you may not be experianced soldering person. So solder the ic sockets first on the circuit board. Solder smaller components first like resistance and disk capacitors, assemble the complete kit one by one. Please make sure that there are no short circuits left on to the circuit board. Check the power supply at all the sockets mounted on circuit board it should be 5 to 5.5v dc.
