low cost Robot soldier

Now a day’s security plays crucial role in any country. So many soldiers are sacrificing their lives for the sake of the country. But the technology is changing day by day. A new area began in the field of science. That is ROBOTICS. Several researches were under taken in the field of robotics. Robots are being used in different fields where there is a difficulty to the humans. Robots can be used even in the field of defense. If we lose a robot we can replace it with another one but we cannot replace a soldier with another.
Many countries started using robots in the wars. For example USA recently developed a robot called SWARD which can carry a rifle and fire at the destined targets. We tried to make a robot that will be faster enough to serve the soldiers in the battle field.
We implemented this project using two microcontrollers 8051 at the transmitter and ATmega16L at the receiver. The robot platform is based on the high performance Jonson-H motors. This robot can be operated through remote through RF communication by using encoder and decoder at the transmitter and receiver with 8bit secured address. This kind of robots helps the soldiers by making some modifications in the robot we can make it to carry the goods at the battle fields to help the soldiers.


for base motors high power metal  gear motors are used
motor ratings:
1000RPM 12V DC geared motors for robotics applications. It gives a massive torque of 10Kgcm. The motor comes with metal gearbox and off-centered shaft. Shaft has a metal bushing for wear resisinance.
