Who has last move in Auto setup?

[pntbll1313]

If I am setting up my robot to be a goalie, and I know my opponent needs to drive straight to the goal in order to score, of course I will try to position in front of them. They will of course try to not let me position in front of them and move their robot. I will in turn move mine and the dance will begin.

I know G6 says that being indecisive about where to position my robot will result in being disabled but who is really being indecisive? Me or my opponent? In my opinion I am not decisive at all. I know exactly where I want to be, in front of them

I would say you. You moved your robot after being set up. They moved again, then you moved a second time. I'm not official in any way, shape, or form.

That said... the GDC's response will probably be "We cannot comment on game-specific scenarios." Or something to that effect.

[Whippet]

If I were a referee (Which I am obviously not) and were presented with that scenario, I would have penalized both teams, because they were both disrupting the flow of the match schedule. However, I am neither a referee, a member of the GDC, or even close to being official. My advice should be taken with a grain of salt.

[Steve Howland]

This seems like a pretty reasonable and important question. Previous games have specified rules for who gets the last right to move, so I'd expect a clarification on this. My guess is that either offensive robots get the last opportunity, or that it will arbitrarily go to one alliance (red) in qualifications and then to the higher ranked alliance in eliminations.

Why not build a robot that detects the offensive robot and moves (autonomously) to block its shot? Makes the OP moot, and maybe you can block all three...

Our team was discussing this, and came to a general agreement that we could not do this before the opponent shot. however, if you were postitioned to the side of a bot, you may able to figure out how far away you had to be from the offensive bot to move sideways and knock the shot away.

genius - maybe use a simple proximity detector pointing down the field tuned to pick up objects closer than the truss

[Steven Smith]

I think the OP has the more realistic scenario in mind where you take an under performing robot and convert it to goalie duty. If you have the capability to program a robot to intercept shots, you should probably be programming it on offense.

If you happen to have a robot on your alliance that cannot score offensively, and can mount an 8' pole to it and stick a corner in the goalie zone in front of your opponent it might have some value. Especially since the average robot will be probably just drive forward and shoot, or even the ones looking for hot goals will be just turning left/right off the center position to shoot.

This would be especially valuable if a top tier robot was able to shoot its own hot ball in < 5 seconds, then intake the goalie's ball and shoot into the other goal. However, that seems like like a tall order.

Regardless (though I expect a clarification allowing the offense last touch), not all field positions are equal. I think placing a disabled robot dead center, as far at as you can while touching the goalie line, and a jury-rigged blocking pole has some value for an essentially very low value team mate. Even if the offense can move, they might not be able to recalculate shot distance to compensate for left/right goals being different distances as they try to shoot the hot one.

Since there would be a max of 3 balls on the field at a time and the balls are fairly big, could you program your robot to detect the balls instead of the robot that way if a team shoots diagonally, your robot will move to the ball instead of just being in front of the robot and hoping it shoots at your pole?

For big kudos, use a Kinect to detect approximate orientation of the robot and eventual approximate trajectory of the ball.

FTC has a 'who sets up first' in the tournament rules. A quick search of the FRC manual has no such rule. Sounds like one may be needed this year. I bet refs will address what 'delay of match' means during the driver's meeting, if this isn't addressed prior to competition.

Even more kudos to the offensive team which has sensors that realize the distance to the wall in the bumper zone is 20-27" shorter than it's supposed to be and thus turns 20-30 degrees prior to the shot. Alternatively, teams could always just aim at the high goal above the low goal. Good luck blocking that.

[jtaffy]

I'm a rookie in FRC this year, but since you get the match schedule ahead of time, wouldn't you discuss with the teams you are in an alliance with to figure out whose auto mode is the most accurate?

And if everyone believes theirs in the best, do the individual scores for each team per match matter in overall ranking?

Or if you are worried about the other alliance blocking your shot, there's a rule stating that we can't pass under the truss until auto mode is over, so why be worried?

I might've misunderstood the thread, so please correct me if I'm wrong!!

Thanks!

Rule G4 says that you can place your robot in your goalie zone for autonomous, which is where the other alliance would try to score. So you can block a bit of the high goal, and/or some of a low goal.

Still, I agree with what other have said, that defense in autonomous is a fallback for robots that can't score.

A well designed and programmed defensive robot could sacrifice scoring 25 points of it's own and play goalie to stop the other alliance from scoring 60 points. That is a 35 point swing. I'm not saying it is likely to happen but it doesn't sound like something that should be dismissed so quickly IMO.

To the OP's question. Our team wondered the same and figured that the head ref should disable both robots.

Successfully defending 3 robots in 5 seconds sounds more like random luck or bad planning. I can't imagine a scenario where all three robots would want to shoot so closely together when a defensive robot shows up in the GOALIE ZONE.

You have misunderstood. Go check out the Autonomous Rules section. You can set up your robot in your goalie zone instead of the White Zone if you want. That robot would be able to attempt to block its opponents' shots.

This thread is about the stalemate that could occur between a robot trying to dodge a blocker and that blocker re-positioning to stay in the way.
