I think inclined planes (wedges) fit right in here. As I see it there are three ways of dealing with "vigorous interaction". One may let the other guy do what he wants and stay out of his way; stand up to the other guy and take the hit head on and hope you survive the impact; or stand up to the other guy but deflect his charge in such a way that it acts to his determent.

In every 2v2 game I have seen in FIRST, a key metric has been the degree to which one can maneuver in the presence of direct opposition (the proverbial pushing match / tug'o'war / carpet melter). This is why we see FIRST robots with six-motor drive trains that shift on the fly into ultra low gear. This is why we continue to strive for wheels or tracks with the best friction properties vs carpet and HDPE.

As long as there are going to be two other robots with a vested interest in preventing your robot from doing what you want, FIRST competitions will continue to be dressed up tractor pulls. As teams strive to keep a competitive edge in this regard they will all eventually run into certain barriers, i.e. the physical laws that govern our reality and the constraints set forth by FIRST. Once we've all maxed out our mu and squeezed every bit of power out of the kit motors, the only place left to go is, quite literally, up.

We'll go from tractor pull bots to sumo bots. Some teams are already on the way. It's not good. It's not bad. It's not ungracious. It's competition. It's invention. It's engineering. Teams are seeking the best solution within the constraints of the problem.

That's the way I see it.

Re: What do you think of a wedge

the only time you are allowed to be aggresive is when you have the potential to score points, and the other team is preventing you, like king of the hill last year - if you were blocking the ramp, you were fair game for a bashing

but if another team is scoring points by manipulating scoring objects, then running into them or bashing them would be considered attempted damage, being un-necessarily aggressive, and poor form.

The year that really started the head to head confrontations between bots was 1999 - the puck - you had to be ontop of the puck to get extra points or a multipler (I forget which) and this was the first time we really saw some pushing and shoving and proverbial hair pulling at a FIRST event

in fact it was pretty tame in the seeding rounds, but in the playoffs bots got knocked off, dragged off, RIPPED off, sometimes leaving a trail of parts across the floor.

in this years game, the only time I would expect to see shoving matches would be if a bot was blocking a corral opening, or trying to control access to the chinup bar. If someone comes over and bashes you while you are herding balls, or placing the 2X ball, I would expect them to be disqualified.

Re: What do you think of a wedge

In 2002, it was stated explicity by FIRST that it was permissible and probably a good idea to ram a robot that was trying to dump a basket full of balls into a goal.

Vigorous contact (on the guy who is about to score) != intentional damage

It's just like football. You can hit the guy with the ball. That's defense. You can't go and smash the kicker while he's doing his nails on the sidelines. That's intentional damage.

I disagree with this analysis.
I expect there will be a great deal of defense in all aspects of the game.
If I decide to cap your "big goal" early in the match to prevent your HPs from scoring... I could then spend the rest of the match blocking you from getting to it. In this case... hits would occur. On stairs...

Anyone else notice the first thing the "kit drivetrain" did during kickoff was drive off the side of the 6" platform sideways? That would be a nasty fall for anyone with a high CG.

Note: I'm not advocating playing dirty, or being overly rough/destructive. We on 229 play clean, but we do play hard. I urge everyone else to do the same.

Build them robust folks... this game is more like '99 than '01.


John

edit: I agree with Joel's above analogy. I think it applies well in this case. If you are scoring... my stopping you from scoring is LEGAL DEFENSE. /edit

Re: What do you think of a wedge

Our robot was shaped like a wedge last year in stack attack... its a simple and easy design (we were rookies... so easy was good for us)... it works fairly well, but its a little top heavy... we almost tipped ours last year going up the ramp...
