You can control one bolder at a time. so if you are not carrying a boulder, you can push others around. If you are carrying a boulder you cannot intentionally herd other boulders. Somewhat a judgment call if you are herding or bulldozing. The Referee’s judgment, not yours, :]
This is a foul
As long as you don’t enter the midline volume and the boulders just get close to but not cross the defenses, it’s legal. You’re saving your fast shooter travel time, they’d still have to cross the defenses themselves though.
Although this idea is creative, it is not likely that many teams will succeed(much less try). If somebody does do it though, get it on camera. I want to see that.
I’m not a reliable source of manual info, but I remember seeing that the judging for reaching a defense is to the discretion of the field judge (proper name escaping me atm), and that they are instructed to rule against the team if there is any question of whether you’ve crossed the defense line or not. I’d assume it’s the same for crossing the midline, meaning I’d be hesitant to even get within two inches of it, seeing as you might get ruled against anyways. Seems like too much of a risk to put in the hands of limited sensor fidelity and possible ostables unaccounted for.
I wouldn’t eliminate the possibility, we’ve seen some pretty crazy autos before, and I wouldn’t be surprised to see someone show up with something insane by champs. It’ll be especially hard with the terrain, but that doesn’t mean it’s impossible.
I’d be inclined to say most two boulder autonomous modes come from the spy bot.
A ref or Head ref if the ref isint sure.
Considering the size of the balls, your margin of error would be several inches. Considering the fact that FRC teams dont have access to any global localization on the field, I can’t see any modern sensors allowing that level of precision.
This. Any team that consistently can pick a ball up from the center will also be consistently at risk of violating G13. There will certainly be teams that do it, but I don’t think that enough people are giving this rule the respect it deserves.
the auto line is pretty close to the midline, if you can detect it with an optical sensor, and slowly advance the robot the necessary amount, you could get right where you need to be.
Disagree entirely. There are teams that have achieved greater levels of precision control in the past, and achieved similarly difficult challenges. Namely, there were a handful of teams capable of retrieving and scoring balls from the side bridges during autonomous in 2012. If mechanical designs permit going underneath the low bar, that’s a pretty similar challenge to spy bots scoring a second boulder in autonomous.
This comparison isn’t particularly valid. retrieving balls from the bridges requires only that you be able to reach the bridge and push it down. Depending on your mechanism your margin of error could be as great as three feet.
Maybe youre missing the fact that crossing the midline is a FOUL, and the ball is exactly on the midline. You see the issue? Your margin of error is now literally the radius of the ball.
I’m not missing either of those. Teams at every event each year run autonomous modes with margins of error less than the radius of the game ball this year. The same penalties existed in 2013, and there were teams that retrieved frisbees from the center line.
Two ball auto will happen, from at least one team at every event after week three. Three ball auto from a spy bot will happen at least once this season.
There was no penalty in 2013 for partially crossing the midline, only completely crossing it. Even the penalties for opposing robot contact were contingent on being completely over the line. Center line auto modes would fight over those discs in the middle, or simply park over them.
I completely agree with you concerning sensor precision, however. This is within the means of FRC teams. The challenge is the 15 second time limit as much as it is precise navigation.
That violates G38 and G40, unless the midline bot waits until the low bar bot shoots before it kicks the next ball, and unless the low bar bot then crosses into the courtyard and comes back before receiving the next ball.
It doesn’t seem like you remember EITHER of those games. In 2013 you weren’t allowed to COMPLETELY cross the line. This means your margin of error is the width of your robot, or most likely the width of your intake, again, several feet.
I’ve never seen a robot that consistently moved to within ±2 inches in the long axis. If you have an example please share.
I remember both of those games plenty well. Please watch your tone.
The exact specifics of the rules in 2013 vs 2016 differ (obviously), but the intent is largely the same. The margin for error for many teams was rather small, especially when it came to aligning their intake devices. The specific example I had in mind:
