This wild, 3D-printed self-solving Rubik’s cube is amazing. To make it work, a Japanese inventor used servo motors and Arduino boards to actuate the cube as it solves itself. Sadly, there isn’t much of a build description available but it looks to be very compact and surprisingly fast.
There is a description of the project on DMM-Make and you can watch the little cube scoot around a table as it solves itself in less than a minute. The creator also built the Human Controller, a cute system for controlling a human as they walk down the street, and the Human Crane Game which is equally inexplicable. If this Ru-bot is real and ready for prime time it could be an amazing Kickstarter.
