This Rubik's Cube solver was designed and programmed using an ARM Powered Android Motorola Droid mobile phone, a LEGO Mindstorms NXT and lots of yellow LEGO technic pieces! Come and see the Speedcuber at ESCsv2010 http://esc-sv09.techinsightsevents.com/. The Android App running on the DROID uses the phones camera to take pictures of each face of the cube and sends the solution to the LEGO NXT controller via Bluetooth.
