The fast rotations of the tiny motors must be lowered by 4 intermediate plastic sprocket wheels. There are no bearings, the wheels simply sit on a steel axis. Motors are powerd by 3V, delivered by two AA batteries. A separate 9V battery powers the electronics. The 2xAA battery case is broken and has been fixed with wires, waiting for a definitive replacement. | |
