| Build your own Rubik's Cube solver from an original LEGO MINDSTORMS NXT (8527 - Orange box) set and an additional color sensor. MindCuber for the original NXT set is shown here racing against MindCuber for LEGO MINDSTORMS NXT 2.0 Build instructions and software will be published soon for this creation. MindCuber for NXT 2.0 is available as a bonus model on the LEGO MINDSTORMS website. mindstorms.lego.com Software source code will be available in the near future at mindcuber.com MindCuber is believed to be the fastest, completely autonomous, LEGO robot to solve the well known Rubik's Cube puzzle. Total solve time, including the scan, averages around 2 min 30 secs. MindCuber's unique mechanical design allows the cube to be manipulated quickly and reliably using only two motors allowing the third motor to be used to move the colour sensor during the scan. The software for the solver runs on the ARM7 microprocessor in the NXT "Intelligent Brick" using the LEGO colour light sensor to scan the cube. The ultrasonic sensor is used to detect when the cube is inserted to start the solve automatically. MindCuber uses a table-driven solving algorithm that was developed to fit in the limited memory of the NXT while generating reasonably short solutions of around 35 to 45 moves. MindCuber for NXT 2.0 can also be seen at www.youtube.com And can also be seen solving a Void Cube at: www.youtube.com Other LEGO solvers can be seen on www.youtube.com and on www.youtube.com Mike Dobson ... |
