Instant overload. Consider that situation with your robot.

Consider this match video. It never seems like we are "beating on the battery". In fact, it looks like our driver is being very meek in this final match. Perhaps there was a problem from the very beginning, like a drive jaguar on both sides not working. However, our problem occurs around 1:20 in the video, when the right drive gives way.
We have omni wheels in the front of our robot that can be deployed for easier turning; they are deployed for the majority of the time except when we are pushing another robot, aiming to shoot, or trying to balance the bridge. When these omnis are deployed, only our back wheels are driven and we do not get a situation where a bunch of wheels are trying to drag across the carpet. Therefore, I believe that our drivetrain should not be demanding a ton from the Jaguars and the battery. Perhaps it is an electrical problem.
We will definitely work through this in the next couple weeks and find a solution. Thank you for helping us and pointing us in the correct direction. Nothin' like having a robot that almost works!
