Android phone solves Rubik’s cube in 12.5 seconds

[Things_falling_apart]

Hello.

I am not sure if this was posted already, but that is pretty impressive feat. Here is the link: http://deviceguru.com/android-phone-controlled-robot-solves-rubiks-cube/


Now if I could only do it that fast...

I'm much more impressed with the 7x7x7.

The 3x3x3 solver is pretty impressive, but I always wonder if they actually use a metric suited to the solver to filter possible solutions. Actually seems like they might have done that here, considering how intelligently the solver seems to handle the cube.


Also: Does anyone know if anyone has ever incorporated a live algorithm into such a solver? There's no need to stop at the first solution found; if you can sometimes improve a part of the solution before the physical solver has gotten there yet, it's worth it. But I suppose these engineers aren't trying to squeeze out every optimization yet.

I wish I was that fast

I can safely say that my PB is faster than that, with my averages close to the machine's average

7x7x7 cube solving robot... Wow...

The WCA should now think of a new discipline: solving the cube with four hands.

 

[Yes We Can!]

The robot uses reduction on 7x7

Think of it this way: a 7x7x7 cube scrambling robot!

The 3x3x3 solver is pretty impressive, but I always wonder if they actually use a metric suited to the solver to filter possible solutions.

I've seen some robots that would be specifically good for doing 2-gen but the calculations don't seem to take that into account and do a bunch of slow rotation.
