PR2 Solves the Rubik's Cube
Loading...
Uploaded by pezzotto811 on Apr 17, 2011
As a side project (and a bit of fun) we got our new PR2 to solve the Rubik's cube. It's not the fastest, but it's a great robot to watch!
In the first phase the robot inspects the cube using vision to find all the colours. Then a (possibly sub-) optimal solution is found. The solution consists in a set of moves that are mapped into a very large sequence of atomical actions. The actions are organised in a state machine and the movements between actions is computed using a graph search algorithm. This is all autonomous.

Kind of depressing how PR2 is so disgustingly slow at doing anything. Do you guys think you'll be able to make it significantly faster in the near future? On what does its speed depend? Thanks.

@Shalek The PR2 might not be a fast robot, but it is the most capable one I have ever seen. Nowadays you will get a lot of robots that are incredibly fast at doing something (see how many of them solve the Rubik's cube), but they can't do much more than simple tasks. The Willow Garage, ROS and the community that is being built around it will hopefully change this. In the meantime, I hope you would reconsider your opinion of the PR2.

not bad - but lets see how he does with a really shuffled cube

@knavehart It does! But it is quite slow, so the video would have been boring. We saw it running solutions with more than 20 moves!
