Rule 18-1:
Strategies aimed solely at forcing the opposing ALLIANCE to violate a rule are not in the spirit of FRC and are not allowed. Rule violations forced in this manner will not result in assessment of a penalty on the target ALLIANCE .
No, the rule regarding the feeder and pyramid safe zones specifically designates that it doesn't matter who initiates contact.

18-1 is intended to prevent things like loading discs into another robot so it has more than 4 or pushing an opposing robot into one of your own partners that is trying to climb, so that the opposing robot gets huge penalties.

Re: How far are people shooting?

Our shooter has been tested at 27 feet into the top goal consistently, but we've shot 50+ feet into someone's outstretched arms 7 feet in the air. Need some more testing
So far, some of the most important things We've learned is that:
There has to be a stable, stable back wall.
If it's a circular shooter, more compression tends to shoot it farther.
No skid tape helps a lot.

Our shooter was shooting like 10-15 feet, and it was a bit disappointing. We were about t give up, but we just moved the wheel in like 1/4 in, and it started FLINGING those things out to 40 feet or so.

Re: How far are people shooting?

We are going to go for the full court shot, probably at the larger target. Our Team developed a 3 wheel system using 2 wheels on the horizontal plane that are belted together and run direct drive off a single CIM and single wheel in the vertical plane that runs direct drive off another CIM. Top wheel is mounted slightly to left of center. Velocity is running over 30 fps and is flying flat and stable. Probably going to have to make some hefty guards for the fast spinning wheels in case of failure.

WOW! That is a great shooter! Very interesting design. I never thought of mounting the well above the frisbee before!

My team is shooting consistently at 60ft away. We are planning on shooting full court, but we don't have to if we are blocked.

Re: How far are people shooting?

We're shooting full court, I don't know what our max range is though. Our shooter is a very different design and is powered by two (2) PG71 motors.

Re: How far are people shooting?

Even more importantly, how accurate are people from various distances. I humanly can easily throw a frisbee 50 maybe 100 feet. I also might kneecap a referee with it.

Re: How far are people shooting?

Our prototype got around 10-15 ft as well, but we're waiting on some parts that should hopefully let us shoot from a lot farther.

We're shooting from three hundred feet. Maybe they'll let us shoot from the queuing line?

Re: How far are people shooting?

during our prototyping, when we tested just to see how far we could shoot it at the one (not adjustable) our shooter is set at, we shot about 40-45 feet

EDIT: and at a glance, the shooter angle seems to be about 35 or 40 degrees
