Moveable Robot -bracelet project with Arduino or with somehow.
e.g. https://youtu.be/fnMmnd9k6q8
For example like in this youtube video but it must be a big or small woman bracelet that people can wear.
It should be able to move and be remotely controlled with a phone or in another way. It can be also like a snake.
