This wild, 3D-printed self-solving Rubik 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.
