In this, Robotic weapon system, we are designing a robot with four wheels. Two wheels are powered by DC gear motor to drive robotic body. These wheels are controlled wirelessly using RF communication system. One DC gear motor is used to rotate gun position in vertical movement and horizontal movements are done by its driving wheels. Gun trigger is control by electromechanical arrangement. Its visual interface is done by wi-fi camera which can be easy view on any wi-fi enable device like smartphones and Computer.
