ArtBot - top electric toothbrush

He doodles, he dances, he is. . . ArtBot! A simple-
Robots using cheap materials.
As a class for families or young people with children, this is a good project because it helps to introduce circuits and simple-bot technology.
Supply: add decoration on vertical noodles.
Be creative like you like.
I use a nice pair of eyes, a face of sharpie, and a plumbing cleaner for my arms and hair.
Remove the end of the electric toothbrush.
Peer-to-peer in the main part.
You should see a plastic cylinder with a battery inside.
You need to pry it out.
You can use your fingers, but if you can't, a set of needles-
The nose pliers will do very well.
The metal motor should also slide out once it comes out.
If not, put the toothbrush on the table and it should pop up.
Now your toothbrush should have four pieces: the plastic top with bristles, the motor, the plastic cylinder that holds the battery and the end with the on/off switch.
Your plastic cylinder should have a small metal arm that connects it to the copper sheet of the motor.
Reconnect carefully.
Make sure the spring is still attached to another copper arm
The spring will connect the negative pole of the battery.
Put the battery into the toothbrush end, then connect the metal arm at the other end of the cylinder with the metal drill bits that fall off the end sheet.
All the metal needs to be connected for the circuit to work.
Test the circuit by "opening" the toothbrush end-
The motor should start to vibrate. Don't worry;
Touch is safe!
Once your device vibrates, continue to tie everything together so the connection is OK and stuck.
Insert the entire toothbrush motor into the top opening of the pool noodles.
Make sure the on/off switch is still accessible. (
You can throw away the bristles of your toothbrush;
You don't need it anymore. )
Finally, attach three or more thin marks to the bottom of ArtBot using tape.
Make sure the markers prompt is pointed out because that's what ArtBot does.
You may need to adjust the mark to make sure)
ArtBot will balance, B)
ArtBot will walk around.
If you make your legs too strong, it won't move too much.
Try and find out the best "pose" for your robot ". And TA-DA!
Remove the marker cap, "open" it, put it on a scratch paper and watch it dance.
