By extension of this ruling, you can control ball direction with active mechanisms above the bumper (relative to world coordinates) if your robot is upside down (relative to normal configuration). This opens up some interesting strategies for controlling the ball returns and executing collaborative plays within an alliance. Team 67 had great success with an orientation-changing robot in 2005, as did team 16 in 2008. Now that the door is open, will we see something similar this year?
