Hamster owners must be used to cleaning up aquariums after their pets make a mess. Why not let them clean up after you? The folks at iRobot have created a prototype vacuum cleaner powered by a hamster running around a spinning ball. Clever, eh?
The movements made by the hamster are transmitted by sensors to the vacuum. The movement made by the hamster determines the direction and speed of the vacuum.
