Make Your Own Robot - best electric toothbrush to buy

Cut the head with pliers or wire cutting machine.
Cut the handle close to the bristles.
Peel off the end of the pager motor wire so that the metal wire of about half an inch is displayed.
Touch one wire at the top of the battery and another at the bottom.
The motor should rotate violently.
Fix the motor firmly to the top of the brush head.
With rubber bands, screw-tie, zip-
Tie, tape or double materialFoam tape.
Make sure the weight can rotate without hitting the toothbrush.
Tie a wire of the motor to one side of the battery and secure the battery firmly to the top of the toothbrush so that the wire is at the bottom.
With rubber bands, screw-tie, zip-
Tie, tape or double materialFoam tape.
Connect the second wire to keep it in contact with the top of the battery. Not moving?
Make sure the bristles are tilted.
The robot moves in the direction that the bristles are tilted.
Go straight or not?
Transfer weight.
The position of the motor and battery affects the way the bristles touch the surface.
Move the battery and motor to make the weight on all bristles even.
The pig stle robot is like a stick.
For example, you bounce up and down the Pogo stick.
The pager motor did the same thing to the toothbrush head-
It bounces up and down.
To move forward on the Pogo stick, you can tilt it forward as you bounce.
Similarly, the bristles of the robot are all tilted.
Because the pager motor bounces back and forth the robot on the tilted bristles, the robot moves forward. Bot bowling.
Set up a bunch of small objects for your robot to knock on the door.
Let go of your robot.
How much did it hit? Super-size it.
Make a huge pig stle robot with a big brush (e. g.
Brush for shoes
Brush (or hair brush).
Connect the electric toothbrush to the brush. Or attach a 3-
V-model motor (
From e-store).
To make the motor vibrate, add a piece of tape to the metal shaft that sticks out the motor.
Or tie a small bead on the shaft.
Off when the axis rotates-
The center weight of the tape or beads will rebound the motor (and the brush)
Push it forward.
