From what you have stated I would say that rule 37 was not violated since it has to do with "robot to robot" interaction. Entanglement is referring to another robot, not with a field element. Tipping over has to do with robot on it's side, wheels in the air. Robots can and do get tipped, but if it's not a high push, then it's likely a function of design.

However, I would agree that sitting there and deliberately pushing your bot in the position described is not in the spirit of a Gracious Professional, no matter what the rules say.

Don't let this experience sour you on FIRST. On balance, the positives far outweigh the negatives. I've been doing this 6 years now, and I have more fun every year, or so it seems. Hang in there!
