Android Phone Solves Rubik's Cube In 12.5 Seconds

DeviceGuru writes "A Lego Mindstorms robotics kit controlled by an HTC Nexus One smartphone successfully untangled a Rubik's Cube puzzle in 12.5 seconds at this weeks ARM technical conference in Silicon Valley. The current 3x3x3 cube-solvers's 15-second average represents a substantial improvement over the 25-second solutions of an earlier version, which was powered by a circa-2006 Nokia N95 smartphone, thanks to a faster (1GHz) CPU, more RAM, and revamped cube-solving algorithms. ARM Engineer David Gilday, who created the robotic cube-solver, claims the current version's algorithms can handle cube complexities up to 100x100x100, assuming he build the mechanics. In terms of racing humans, Gilday says the Lego robotics kits can only manage around 1.5 moves per second, whereas human players can make between 5 and 6 moves per second, amazingly enough." Update: 11/12 03:45 GMT by T : Apologies to creator David Gilday, whose name was earlier misspelled.

    "MichaelKristopeit172" is operated by a pathetic individual attempting to steal my identity.

    to the individual responsible: present yourself to me, admit what you've done; and i will bring upon you the ultimate punishment for your transgressions.

    granted, i wouldn't want to admit that i was you either.

    you ARE completely pathetic.
