Funny to build. Made entirely of wood, in addition to the plastic gears (these are the wheels used in the mini tracking machines) there is a small gearmotor that ensures the necessary power, supplied by two 1.5V (AA) batteries. He can easily draw complex circular figures. An easy summary of physics, mechanics and electricity.
