The kind of robot you'll be able to make at home most likely won't be able to do the laundry or dance like Michael Jackson. A "vibrobot" is a robot that uses the staccato rhythm of vibration as a means of locomotion, and this concept can be harnessed to create your very own zooming, ricocheting robot.

Snip the head (the part with bristles) off the toothbrush. Leave at least 1/2 inch of neck attached, and set the snipped-off head bristles-down on your workspace.

Lay a strip of double-sided sticky tape across the flat top of the toothbrush head.

Position the motor at the edge opposite the snipped-off neck, making sure that the turning shaft is clear of any obstructions.

Lay one of the motor's wires down flat against the sticky tape.

Stick the coin-cell battery down on top of the wire, pressing firmly to ensure a good connection.

Bend the other wire down to contact the top of the battery. The motor will activate and send your bristly robot scooting at impressive speed across any flat surface you choose.
