Vibrohod is a brush facing down with a bristle, on which is attached an electric motor with an eccentric and a battery. When the motor shaft rotates - the eccentric (the load whose center of gravity does not coincide with the axis of rotation) rotating, creates a vibration. The vibration is transmitted to the body of the brush and it starts moving. The direction of movement depends on many factors: the surface, the mass distribution on the brush, the angle of inclination, the shape of the bristles, etc.

To build a vibro-pass, we need a brush (bought at a hardware store), an electric motor (bought at radio or removed from an old toy), and a battery.

Fasten the motor to the brush You can do anything you like, in this case double-sided tape was used. The eccentric can be made of tin, for example, or by epoxy gluing a nut. You can make a fastener from a paper clip, in general, there is a lot of space for creativity.

Run and see what happened) If the brush moves incorrectly, then changing the location of the motor or batteries will shift the center of gravity - this will change the nature of the movement.

The second optionwas proposed by the site and it is distinguished by its miniature. The toothbrush head was taken as the basis, the motor from the cell phone shakes (the eccentric is attached at the factory), and the battery is a lithium tablet, such, for example, are installed on the computer's motherboard.

To launch a bot, you need to press a bare wire to the battery contact with a piece of adhesive tape. This bot was even called a" cockroach ") You can make several such vibrating ways with your friends and arrange competitions.
