Sorry about that.

The order of events which I was trying to express are:

1. Our robot's sitting still.
2. Another robot begins to push our robot.
3. The other robot which is geared to push better then our robot over powers our motors
4. We get pushed backwords

At this point are our motors broken or not?

Based on Jeffys response:

Your motors would have to reach free speed and in that case, you are already being pushed faster than your motors maximum speed.

BRAKE mode won't BREAK your motors, and it won't keep you from being pushed, but it will drive a little bit different, and resisit slight bumps from other robots.

It does not seem that we will have to fear about our motors breaking.


Thank you for all of the help.
