In the past I’ve seen hand built robots that can solve the Rubik’s cube. I’ve been impressed by their terminator like appearance, sophisticated programing and implementation (as seen here). Until I stumbled onto TiltedTwister.com. These guys took the Lego Mindstorm (which is a toy under $250) and gave it a shot of steroids… Barry Bonds would be proud.

“An ultrasonic sensor detects its presence and starts to read the colors of the cube faces using a light sensor. The robot turns and tilts the cube in order to read all the faces of the cube. It then calculates a solution and executes the moves by turning, tilting and twisting the cube.”

Performance Highlights:

• Scanning the cube: 1 minute

• Calculating a solution: 20 - 40 seconds

• Executing the moves: 1 - 5 minutes. Average 4.5 minutes (60 faceturns)

• Average total time: 6 minutes
