What is motor & how we use it in robotics: according to Wikipedia, An electric motor is an electrical machine that converts electrical energy into mechanical energy. In robotics, motors convert the electrical energy that powers the robot into mechanical energy that allows the robot to do work. Motors are mainly used to move a part of a robot. In a word, Motors and actuators give life to a robot. There are many kinds of motors that can be used in robotic applications. Each type of motor is used for a different purpose. Motors can be attached to wheels that drive a robot around or might work as a joint in a robot arm to move.
