Check Team 45
Team 45 had some sort of a bar that extended out with a finger that would go into the slot between the Bar and the Wooden Base, they were excellent at grabbing from odd angles.
We too thought about it after our robot took so long to grab the bar since our design required the goal to be lined up pretty sqaure and after reigonals the best design we could think of was arms similar to the Hot Bot. They used them mostly to grab Big Balls with but they reached pretty much around the goal so they could grab it from any angle and even if it was off center from the gripper. However in the super short time period we completely messed up the cam action and gave the arms so much leverage the air cylinders couldn't hold it securely (completely backwards from what we wanted). With either of those 2 designs you would have a sure winner. Someone from either of the teams can explain their systems more clearly I am sure.
I have pictures, if you need them of some of the above stuff

I had such high hopes for that contraption too!
