How far are people shooting?

[z_beeblebrox]

Yesterday, our prototype shooter (CIM and miniCIM directly driving 2 8" AM pneumatic wheels) was easily firing across our 30' practice room with little vertical drop.

Our team plans to be versatile with shooting positions, as we have our shooter on a tilting mount, but I expect we'll primarily be firing from the back of our pyramid and from the feeder station (if we can get adequate accuracy at such a long range)

That curve.

How are your motors holding up? We were using an 8 inch AndyMark FIRST directly mounted on a mini-CIM shaft and got some good shots until the motor bearing gave out.

FIRST team 4057 has a prototype shooting accurately from 55 feet out at 60% power. It was at this time we realized the hazards of testing inside as we ramped up the power and put a dent in the duct system in the school.

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.

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.

So far they're ok as the motor is well supported, but we haven't run it much yet.

i believe our robot will be capable of shooting from feeder station but i fear a defensive robot will park infront of us nd block us. is that legal?

As long as they adhere to space restrictions, yes.

There is no rule against simply being in the way of a shooting robot, but there are plenty of rules you could break while doing so (pinning, etc). See section 3.2.6 "ROBOT-ROBOT Interaction" of the game manual for more information.

We're planning on scoring a little more than over 9000 from the goal. Give or take a little.

Oh, y'know, we're attending Greater Kansas City, but plan on outscoring OP Robotics at their regionals...

We shoot from about 60 feet away. But the frisbee doesn't go nearly that far
From 12 feet we're 100% easily, from 25 feet almost but not quite, we are seeing some curve at that point. They tell me 40 feet is not bad, but I have not seen it myself.

We're shooting about 20ft dead straight, no wheels.

No wheels? Care to elaborate? Sounds fascinating.

30ish feet
