I have been looking at a lot of robot advances and various clever kits. Some inspired by nature, some just plain brute force servo controlled kits.
This however is something that is uncannily amazing. It is a Rubik’s Cube solver robot. Solving a cube is relatively straight forward as a maths puzzle. This however has to visually examine the cube and then solve it and manipulate the answer

The Cubestormer II is, as you can see, using LEGO (four MINDSTORMS NXT kits) a Samsung Galaxy S II smartphone is running the app to analyse and trigger off the solving. i.e. easily accessible technology combined in a very clever way.
