Bristlebots having a meeting

Minion Bristlebots

What?

My own take on the classic bristlebot, with a 3D printed battery holder.

These little buggers move around thanks to the vibrations from the motor.

Why?

To give a workshop.

How?

The vibrations from the motor make the bot move around, by bending the hairs of the toothbrush backwards, the bot moves forward (kind of :D).

Requirements are:

1 toothbrush
1 vibration motor
1 CR2032 battery
1 3D printed battery holder (found here)
hotglue
(googly eyes)

Instructions on how to put them together:

step 1: cut the head of a toothbrush
step 2: print the battery holder
step 3: attach the vibration motor to the battery holder and put the 2 leads into the holder block so the battery can touch it.
step 4: hotglue the holder to the toothbrush head
step 5: cut (if needed) the toothbrush hairs to length and bend them backwards so the bristlebot will go forward instead of in circles.
step 6: decorate and race!

 

Current status:

Finished, thinking about making a racetrack for them.
