LEGO NXT Rubik’s Cube Solver (VIDEO)

Having trouble with your Rubik’s cube?  Daniele Benedettelli has created an automated Rubik’s cube solver called the LEGO Rubik Utopy.  On his website, Daniele describes, “A motor actuates a prismatic joint that pushes the side of the cube (the red side in the photo); another rotates the cube’s support; the third one has the double function to help the pusher arm to accomodate the cube on the support and to hold the cube while the bottom face is rotated. The robot uses 2 touch sensors as limit switches for the arms and a light sensor to zero the rotating base. It’s not useful to waste more words on mechanics, to understand the whole thing it’s better to take a look at the video!”
