Simone Giertz, who lives in San Francisco, USA, has created an automatic toothpaste robot "Toothbrush machine" that fulfills the wishes of such lazy people. The production method is published in instructables.

"Toothbrush machine" is a toothpaste robot made by Giertz for a kids show. It is a full-scale (?) Device made by combining the one-board microcomputer "Arduino UNO" often used in electronic work and the robotic arm "MeArm".


To brush your teeth with the "Toothbrush machine", first apply toothpaste to your toothbrush. Then put on the helmet and turn on the switch. Then, the arm with the toothbrush that was folded on the helmet moves to the mouth, and the toothbrush is moved violently to the left and right 10 times to brush the teeth.



"Toothbrush machine" is still in the pilot version. You can only brush your front teeth sideways. Giertz himself admits that there is almost no toothpaste effect, and at the moment it is still only a "ponkotsu robot".
In fact, Giertz is a big fan of Reddit's "Shitty robots", a collection of footage of useless robots. "Toothbrush machine" posted a video on Reddit, thinking that it could join the ranks. Posts have gained a lot of popularity, and Giertz is flooded with requests to teach him how to make them. For this reason, the production method was released in instructables this time.
Anyone can make a "Toothbrush machine" by following the instructions in the instructal bles. In addition to the "Arduino UNO" and "Me Arm" mentioned above, a helmet and toothbrush are required for production. According to Giertz, it costs around $ 140 to buy all the parts. Helmets are especially expensive.
Some people may be reluctant to spend as much as $ 140 on a low-efficiency toothbrush machine. However, for example, when somewhere on the face is itchy, it can also be used as an "automatic face scraping machine". Pay $ 140 and scratch your face. This is a millionaire, isn't it?
By the way, this "Toothbrush machine". Isn't it perfect for children's summer vacation independent studies? If you are a teacher who understands the difference, just because you are using "Arduino UNO" may give you a reasonable evaluation.
