Lego Robot Solves Rubik's Cube Puzzle In 3.253 Seconds 60
A reader sends this news from CTV:
"The Cubestormer 3 took 18 months to build but only needed 3.253 seconds to solve [a Rubik's cube], breaking the existing record. Unveiled at the Big Bang Fair in Birmingham, U.K., the Cubestormer 3 is constructed from the modular children's building-block toy but uses a Samsung Galaxy S4 smartphone with a special ARM chip addition as its brain. It analyzes the muddled-up Rubik's Cube and powers each of the robot's four 'hands,' which spin the cube until all sides are in order. Created by ARM engineer David Gilday and Securi-Plex security systems engineer Mike Dobson, Cubestormer 3's new record shaves just over two seconds off the existing record, set by Cubestormer 2, which the pair also built."

Well, I guess it also depends on "how well" the cube is when you start.
Is there anybody that knows the longest possible sequence of move one would have to do in order to resolve the cube? In order words: what is the worse configuration to start with when you try to resolve it.
I think our robot could spend more than ~3 seconds resolving it with worse configurations.
Now: Let's design a robot to mix the cube for the other robot and have a data set, not just one run.

Try reconfiguring (ie take the stickers off and put them back in diferent places so there is no solution) and then see how the robot does...
