Daniel,
Sorry but I disagree. Stuffing an opponent into a goal to take them out of the game and to block a goal is not what I would expect in this competition. The goal is wider than most robots so there is nothing you can design around. You might as well push them over the side of the field border. The effect is the same.
If you know that a robot can be tipped and use that as a strategy then I think that is also wrong. To intentionally go out and tip over robots that are easy (by virtue of their design) is not in the spirit of the competition. I read G36 and G37 as support for this belief.
I want to lose a match to superior robot/driving/strategy. I don't want to lose to a team that has taken out my alliance partners by tipping and/or entanglement.
That being said, humans make mistakes, refs included. They miss calls sometimes, that affect match outcomes. What we see from the stands is not always what they see from the field, up close.
