Rubik's cube solving robot

This blog is dedicated to build a Rubik's cube solving robot. I'll not give you any guarantee to even update this blog or finish it. I just want to share and discuss some ideas.

The first thing I did was to buy 3 Rubik's cubes at taobao.com (a kind of Chinese Ebay), each around 10 RMB.  I bought 3 pieces, because I wanted to avoid one or two samples are getting damaged during my experiments and evaluations and I needed then to find exactly the same kind of probes for my experiments again, which can be quite annoying.

Observes the sky with a video camera, transmits a ring tone to all walkie-talkies in a range of 2km, beeps to find it again

Explosion

First static test firing with hexaphenox propellant, using an empty C6 motor casing. Combustion chamber pressure was way too high which led to the explosion of the motor. Hexaphenox is a rocket fuel I have developed:)

Improves the obstacle recognation of Sharp IR distance sensors
Sharp IR distance sensors are very often used in robotics. But I always found it annoying, that they do not recognize very small objects, chair legs or even walls … Read more
