Lego Mindstorm Solves Rubik’s Cube
Posted by: scooter in DIYGrid, Robot Technology, ToysIn 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
