Small Unarmed Robot for Defense and Security:A Cost-Effective Approach Using Arduino Uno

This paper is about designing a robot which is economical and can help military by transmitting video in closed quarter combats. small unarmed ground vehicle (SUGV) is a robot consisting of a toy car acting as a platform and arduino uno controller,batteries,Bluetooth module and a smartphone are mounted on it.The DC motors of the wheels are connected to the arduino controller and via the Bluetooth HC-05 module the commands from the accelerometer of the smartphone are sent to the microcontroller depending on which the motion and direction of the wheel can be controlled. The robot can move in forward,reverse,left and right directions and this movement is controlled by the droid to arduino app installed in the smartphone.The smartphone mounted on the platform uses skype video conferencing application to send the live video of its surveillance to the skype application installed in the laptop using internet. By using the video soldiers can take suitable action.Thus SUGV helps in minimizing risk to a soldier's life.
