LED Cube 8x8x8
Android LEGO Rubik’s Speedcuber
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!
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.
