Robots are programmable machines built to mimic human actions. One such action is locomotion of robots which is the recent area of research. Two-wheeled robots which diligently stabilize it may contribute to the locomotion of robots in upcoming decades. In this paper, the PID controller and Arduino are utilized to design the self-balancing robot. This paper focuses primarily on developing a controller that will aid the robot and test against several parameters such as position, balance along vertical axis and signals for controlling. The accelerometer and gyroscope sensor values are used to determine the precise position of the robot in 3 dimensional space. The sensor values are sent to the controller which controls the rotation of wheels thus aiding in balancing the robot. The two-wheeled robot turns precisely while navigating through different obstacles as against four-wheeled robots.
