ABSTRACT
A robot is an intelligent machine that can interact with the environment to perform specic tasks to reduce human effort. Various types of robotic systems are available; however, the majority of robots have some common features. Almost all robots have a movable body, some of them have motorized wheels, whereas others have many small movable segments that are typically made of plastic, wood, or metal. In some robots, several joints connect the individual segments of the robot together. The actuator of the robot spins the joint with wheels or a pivot segment.
