I made a robot to cut my hair with scissors



My hair is getting too long so I decided to build a robot to cut it for me. To support future projects like this check out my patreon: http://patreon.com/stuffmadehere

If you like this project you’ll probably like my iPad case that lets you see blindfolded.

The possibilities for this kind machine are endless with the most interesting things being haircuts that are too hard for human hair cutters to achieve. Imagine a mathematically perfect fade from one side of your head to another. Or imagine if I added a trimmer to this and cutting perfect lithopane pattern into your hair. I consider this the first generation machine and hope to build another to explore some of the crazier haircut concepts. A colleague suggested adding a precision hair dying attachment and doing some crazy multi-color hair styles. I wouldn’t say that’s really “my jam” but I might try it in the name of science & engineering.

This isn’t just limited to humans either. Imagine sticking a poodle in this or making a bigger one to create topiaries. Lots of fun ideas….
