Not true.

We saw a West Michigan team yesterday at the 2771 Code Red lab shooting into the goal at the top of the tower at will. They are also hitting the three point shot without any trouble as well. I will not spoil their reveal by providing their team number. We also saw a team making high percentage shots from the feeder station.

A lot of things I saw today; Only 1 robot had a floor pickup mechanism and very rarely used it. The last 30 seconds there were quite a few Frisbees on the field & a frenzy of Frisbees flying everywhere from the HPers. The nets did have to be raised higher up to protect the scoring table. They will need to add additional netting at events on the ends to protect crowds & any audio/visual personnel & equipment. The net opening where teams enter/exit will have to be modified so robots don't catch the drooping netting. there were issues today & we came up with a temporary fix. FIRST has been made aware & hopefully will provide a solution for week 1. Numerous robots were able to rise to the 10 point level during the last 30 seconds.

One alliance in elims had all three at the 10-point level. It didn't win for them.

Shooting through the pyramid at the 6-point goal in auton. is quite a lead to make up. With an alliance partner also high % in that auton. goal makes an even better start. I was wondering if frisbee transfers during auton. would be possible as they were in RRumble.

Getting to the feeder station and back is very easy.

I would say easy but slower than vacuuming up all the frisbees under the goal and scoring them .

Not if you had a determined and skilful interloper like 2168 in your way. Ask 177 how their trips to the feeder went during elims at Suffield. 177 made a lot of good shots on 3&6 goal but they had to (?) do it from a certain spot next to their pyramid.

I think it will be harder in this game because you can't roll frisbees to your partner like you could with basketballs. I suppose a shooter could spit their frisbees on the floor for partners to pick up, but I think that would be too unpredictable to pull off.

In Auton, the frisbees only have to be touching your robot, so a robot could simply drive backwards and let another team shoot the 2 disks on the floor.

Through our tests on almost a full size field, we found that pickup from ground from arbitrary positions on the field wasnt as effective as going to the feeder station and back to anywhere around our pyramid to shoot.

Our goal was to hit over 100+ points per round with no opposition and rain of frisbees which we did.
Hopefully, with the rain of frisbees, opposition, and other great points noted here, we can still contribute as best we can.

Sounds to me like floor feeders are only good during auto period, but then again, we havent seen the elite teams unveil their effective floor feeders as of yet.

I'm calling that part "the Blizzard." Sort of New England thing this year. Wall to wall "snow" by the time the match is over.

Our shooter works very well shooting into the 3pt goal with chains from the feeder station and from the front and back sides of the pyramid.

Last our 10pt climber worked like a charm and was one of the fastest and easies hanging mechanisms at our event. 3 seconds and only 25psi.

We also learned that if a frisbee is upside down and gets stuck on your wheel,it can really mess with your driving until it gets dislodged.

What kind of pickup did you use?

One thing @ Rally that stuck out was some teams sported some serious cannon that fired Frisbees at a shocking rate of speed. While FIRST has cracked down on Human Players unleashing an insane hail of Frisbees I actually wonder how soon is it FIRST issues a speed limit for firing Frisbees like they did with the robots back in 2006.

I sure hope they don't....

I don't think FIRST will issue a speed limit like they did in 2006. 2006 was the first competition with projectiles and I think the speed limit they enforced that year was more of a precaution than anything.

Unfortunately, I don't think there is a velocity that the frisbees can be effectively launched at that is also safe for human impact. That being said, if a robot at competition repeatedly shoots frisbees out of the field in an unsafe manner, I assume the refs will issue a warning followed by a yellow card for additional aggregious infractions.
