I have to agree with 980, although I don't agree to it being as "simple", but what other robot can do so much and stay in one place? The arm resembles a regular human arm in that it can move in any direction possible with the 4 degrees of freedom. Up-down, round and round, that robot was just crazy. For the San Diego Scrimmage they did put on a simpler rigid end for an arm, but nothing beats the arm at nationals. At every regional and competition, it seems like the team is just fixing something on the arm to make it function better.
