Update - The software now works with the standard 1.06H firmware version, but needs an additional 'Brick App' program to be started manually each time it's turned on as detailed on the MindCub3r website. This is a modification of the standard LEGO firmware that works better with the Color Sensor in the way it's being used for this robot, and allows it run the background solver process. The software consists of four components:

The MindCub3r uses a standard home edition EV3 set, 3 motors, and 2 sensors. It achieves this with multiple EV3 sets, who knows how many sensors, and runs software on an Android phone. This is not to be confused with the Cubestormer 3 which recently made the news for breaking the world record time for cube solving (human or machine) in 3.253s. The MindCub3r for EV3 can solve it in about 1.5 mins. Over at they have freely available designs for a Rubik's Cube solving robot for either the NXT 2.0 or EV3 LEGO sets. It just so happens there is a fantastic project already available that creates one from just the 31313 EV3 parts - the MindCub3r created by David Gilday. Rather than pick another of the community supplied robots that come with the EV3 software, I wanted to build a Rubik's Cube solving robot.
