2005 had a great game! It was great to play with an unusual field piece.
If I recall correctly, there were two teams that capped the side goals in autonomous, with 66 definitely being one of the two. One team had an award out for the first team that capped the center goal in autonomous - it had the largest point value that year. That never happened in competition that year.
Above is a picture of the closest anyone ever got to that goal (Lone Star Regional - Team 624). I can't seem to find the video, but it was placed in the position shown and the robot backed off during the 15 seconds. However, it didn't count as the tetra was caught on a zip-tie that held the vision panels on. Using the vision system at championships became particularly impractical due to the lighting of the Georgia Dome that tended to cast shadows everywhere.
624 had a good minimal design that year - 1 arm that rotated at the "shoulder" and was powered through a beast of a 24" long piston (with variable control), plus a 6WD drive train. The hand folded up to start the competition, but unfolded for the entire match. This was definitely one of my favorite games to design for.
As for fantastic design concepts, 118 put out a relatively simple design (for them). Swerve drive + rotating elevator turret + dual arms with 1 controlled degree of motion each once the arms unfolded (piston that extended a PVC tube from the "elbows" of the arms). Dual arms allowed them something many teams did not consider - moving more than one piece at a time. Added to a swerve drive and rotating turret, they dominated. They only lost one qualifying match at LSR that year, and it was one in which they were facing a strong alliance with 2 no-show/dead partners. They went on to have a strong showing in Atlanta.
