CMU has announced 20 Personal Exploration Rovers (PERs) that will make the round to science museums around the US. The Linux-based robots will simulate real Mars rovers within "Mars yards", sand-box like replicas of Martian terrain. CMU and NASA are collaborating to build the robots in an effort to teach kids about robots. Future plans of CMU's Personal Rover Project include lowering the cost of future rovers to the point that kids can buy one and take it home with them. Additional photos and video are available from the CMU site and from NASA TV.
