Re: pic: BeachBot Pseudo-Crab drive, partially assembled

"Fixed" relative to what? Since all the other parts of the trailer hitch constraints seem to revolve around the bumper perimeter, I would be inclined to say that the bumper perimeter would be the most logical point of reference. In the case of 330's design, this is a fixed point.

As a side note, 230 had a similar design except that their outer frame is free spinning and the robot rotates inside of it. They were allowed to compete at Boston, and I would consider it legal for the same reason as stated above.
