A brute-groom, a shchetinobot, a vibrohod is a simple toy that uses vibration for its movement. Due to its simplicity, the vibrator can be recommended for assembly to children.
Vibrohod is a brush, bristled down, on which an electric motor with an eccentric and a battery is fixed. 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 transferred to the brush body and it starts moving. The direction of motion depends on many factors: surface, mass distribution on the brush, angle of inclination, shape of the bristle, etc.
To build a vibration shroud we will need a brush (bought at a hardware store), an electric motor (bought in radio receivers or extracted from an old toy), and batteries.
You can attach the motor to the brush as you like, in this case a double-sided adhesive tape was used. Eccentric can be made from tin, for example, or epoxy glued nut. It is possible to make a fastener from a paper clip, in general, the space for creativity is large.
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 variant was proposed by the site evilmadscientist.com and it is distinguished by its miniature. The head of the toothbrush, the motor from shaking the cell phone (on it the eccentric is fixed in the factory), and the battery - the lithium tablet, such, for example, are installed on the computer motherboard, is taken as a basis.
In order to run the bot you need a piece of adhesive tape to press the exposed wire to the battery terminal. This bot was even called a "cockroach") You can make with your friends a few such vibrohods and arrange competitions.
For vibrating belts, bristles are not a mandatory factor, if the vibration is strong enough, the can can also be moved on a 3-foot support. Here's a pretty interesting option
If you run it on a sheet of paper, the markers will leave a trace with a curious pattern.
