Where does a robot get its power? How can a small robot bug crawl across a wall? In this engineering lesson, our teacher helped students understand how motors and gears work by connecting the concept to something they see every day—a car. Students learned that just as a car needs an engine to move, a robot needs a motor to provide power. The motor turns a small gear, which then drives a series of larger gears. Together, these gears transfer motion throughout the robot, allowi
