At Lone Star Regional, team 118 (Robonauts) used a "v6 engine"
http://youtube.com/watch?v=h3l6Xqts4to
they basically put together 6 motors to create a monster v6 engine. Their arm was very quick and effective, allowing them to score a row of 8 by themselves. We *team 846* had saw that video before we arrived at the regional and were somewhat curious how we were going to defend them. When our match against them finally came, we just double teamed their robot, eventually blowing out their v6, forcing them to use their backup v6.
A double team can easily force a blown engine = great defense.
