I'd Beat It (With A Hammer!): World's Fastest LEGO Mindstorm Rubik's Cube Solving Robot
Granted we've seen LEGO Mindstorm sets people have built to solve Rubik's Cubes in the past, but never anything that moves with the speed and dexterity as CubeStorm CubeStorm Cubestorm. Whoa, nice echo effect. Kidding, I'm hiding in the closet (my mom's trying to drag me to a doctor's appointment).
The Worlds Fastest Lego Mindstorms RCX Speedcubing Robot. Built entirely from lego elements with a lego web camera to scan the faces of the cube, The solve engine (algorithm) running on the computer is provided by the incredible "Cube Explorer "software which also provides the colour recognition required to determine the exact location of each coloured square. Thanks to Herbert Kociemba for making his work available to anyone wishing to use it! Respect! "Cube Explorer" has the ability to produce very fast solutions to a successfully scanned cube, usually around 20 face turns! Doesn't sound a lot , but it is believed that around 20 turns are enough to solve ANY 3x3x3 cube combination. I'm still working on "CubeStormer" I would like to see it reach sub-10 and feel it's close to that. but reliability begins to suffer when you start to push things just that bit too far.....
You know what else begins to suffer when you start to push robotics too far? Humanity. Just sayin', you ever seen that movie Terminator? I haven't. Jesus, I've got enough nightmare fodder.
Thanks to Osku, Logisticz, Gir, Ringo, RaÃºl, meeotch, Frank, james, Bolleke, PrestickNinja, raficus and Clint, who would have disassembled that sucker and built a sweet-ass LEGO castle.
