Re: Tipping opponents robots

These were understandable mistakes given the amount of stress that the judges were under, but the one thing that was really excessive in its not-being-called was deliberately aggressive play. One team in particular became notorious; nearly every single robot that tried to play defense on them wound up flipped, broken, or stuck in one of the goals and unable to get out because of the two-inch lip. We were one of the very few teams who tried defending on them to make it out of the match intact, and that was pretty much only because a) we had an exceptionally sturdy and low-to-the-ground robot and b) we crossed the bump with a minute remaining to go help our alliance partner in the midfield score some points. Not a single penalty was ever called on them, and they ended up doing extremely well in the tournament. I don't mean to insult them, because they really do have a great robot and a talented driver, and they completely deserved their win, but I felt that the level of aggressiveness that was displayed as a part of their strategy was questionable and should have been called.

Even more prevalent than "accidental" tipping was getting jammed into the goals. If you can believe it, it was actually a defensive strategy discussed by certain teams to wait near the bump until a ball was herded into the goal, then charge the team that herded it in and ram them so hard that they would become stuck, effectively pinning them for the rest of the match. Teams that tried to play defense on robots with high traction by getting between those robots and the goals sometimes ended up with their robot pushed in instead of the ball, effectively neutralizing the entire alliance's defensive capabilities. Maybe the next update should have something to do with this...
I'm sorry, but this post reads to me "Boo Hoo, Someones bot is playing agressive defense and my offensive bot cant score".

We play at GSR where defense is well known and played very hard. Our robot (while playing in the defensive zone) was flipped 4 times, and self righted 3 of those times (seems I remember something about selfrighting from kickoff). Tough defense was played, and those that scored earned those scores (congrats to them).

As far as stuffing a team into the goal, please find the rule number that prohibits that strategy. It sounds to me like your team did not take that 2" lip and memory foam into account when you built your robot. Not the fault of the defending robot.

Bumper to bumper contact is allowed (and even encouraged) within the rules. The higher bumpers this year created a lever arm that made it easier to tip robots. I'll bet you dollars to (Dunkin )donuts that the defending bot wasn't purposely tipping others ... it was just happening with decent contact and high traction wheels.

Your robots are also supposed to be built with "vigorous (sp?) interaction" in mind. If bumper to bumper contact causes damage, then it most likely was not built strong enough. Again, we play at GSR where aggressive defense is always expected.

The above isn't meant to offend anyone (although it probably will) but I get sick and tired of hearing how unfair it is when teams play solid hard-nosed aggressive defense. Build your robot tough, and learn to play when the defense is strong.
