I don't know the detailed specs on the opposing robots.
We will be in St. Louis, but I have no interest in setting up an "experiment" where you attempt to buldoze our robot.

At least some of the weight is transferred to the opposing robot.

Additional functionality.
The robot operates in a robot-centric mode normally, When the driver initiates crab control, the gyro is reset and the robot is "field-centric" from the robot's orientation at that point. This gives the driver a twist input while in crab. If the twist input isn't used, it is the same drive code that we used for years before. If anything, it gives the driver one more thing to think about. It is, however extremely effective once mastered.
