Power Supply
Several types of power can be utilized in a robot structure. The first that may come to mind is electrical power, to run the computer chips and electric motors. Many small-scale robots rely entirely on electrical power. Compressed air, hydraulics, fuel cells, solar panels, steam, tightly wound springs, and gravity can also be used, depending on your facility with these technologies.
Because it’s completely predictable that you’re going to use an Arduino of some sort along the way, you should make at least preliminary plans for providing electrical power in the robot.
The typical Arduino Uno or similar circuit requires a steady stream of regulated electrical power to operate reliably. The on-board voltage regulator on most store-bought ...
