If you were to ask a random passerby to describe what a robot is made of and how it is powered, they would likely tell you that a robot is made of metal and requires electricity to operate. Experts, however, would likely say that robotic control systems consist of electronic boards connected to a variety of sensors—from light detection and ranging (LIDAR) sensors to cameras to electronic skins—and that current power sources range from standard electric batteries to hydraulic pumps.
