Radio Controlled Combat Robot

Combat robot receiver block

We cannot forget 9/11 when 101 people including nine foreigners and 14 policemen have lost their lives while about 300 people were injured in the worst terror attack seen in the country in which desperate men fired indiscriminately at people. Being an ex– defense person , my blood was boiling as our brave solders were fighting the militants to free all the hostages from Mumbai hotels. It struck an idea in my mind, why cant we make a robot to tackle such type of situation.

This combat robot is an improved version of my previous robot which I designed years ago named SPY ROBOT.

Out new Combat robot is radio operated , it has got two barrel turret through bullet can be fired, radio camera in synchronization with the turret can rotate up and down ,left and right up to a safe firing limit. turret and camera mechanism has been installed on my previous spy robot vehicle, which has all the function like tank, Turing to any angle on its axis, moving forward and reverse turning left and right, running instantly into reverse direction.

This robot is radio operated , self powered , and has all the controls like a normal car. A pair of 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. It can silently enter into enemy area and send us all the information through its’ tiny camera eyes. It is designed for, fighting as well as suicide attack.

Heart of our robo is intel’most power family of microcontroller 8051,we are using at89c2051 Two microcontrollers ic2 is first microcontroller which acts as master controller ,decodes all the commands received from the transmitter and give commands to slave microcontroller1 ic3,and slave2 ic5. Slave microcontrollers are responsible for executing all the commands received from the master and also generating pwm pulses for the speed control . Ic4 is ld293 motor driver ic which drives two nos motors m1 and m2.these two motors are vehicle driver motors. Slave2 microcontroller controls the gun and camera movements in up/down ,left or right direction. Ic6 is driver ic which drives gun and camera motors in two angles.


a. moves in forward direction

b. moves in reverse direction,

c. speed controls in both the direction

d. it can even turn left or right while moving forward or in reverse direction.

e. Instant reverse or forward running without stopping

On the spot left or right turn to pass through the nerrow space

f. We have also added head light, back light.and turing lights to left a right . These lights automatically comes on while robo is in Movement.
