Shchetinohod

Vibrohod is a brush with bristles facing down, on which an electric motor with an eccentric and a battery is fixed. When the motor shaft rotates - an eccentric (a load whose center of gravity does not coincide with the axis of rotation) rotates and 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 will need a brush (bought at a hardware store), an electric motor (bought at radio or removed from an old toy), and a battery.

You can fix the motor on the brush as you please, 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 clip from a clip, in general, there is a lot of room 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.


Second optionIt was proposed by the site evilmadscientist.com and it is distinguished by its miniature. The head of the toothbrush, the motor from the cell phone shakes (the eccentric is attached at the factory), and the lithium tablet battery, such as, for example, are installed on the computer motherboard.

In order to run the bot you need a piece of adhesive tape to press the bare wire to the contact of the battery. This bot was even called a “cockroach”) You can make several such vibrating rods with your friends and arrange competitions.
