But that doesn't matter, because you can put your 45 discs at any of the three stations in any configuration as you please (see Q&A).

I have a feeling that we are going to see a lot of full court shooters so im gonna also agree on the stock for 84" tall defense robots to be really high.

We've finally gotten our hopper-to-shooter prototype up and running and are moving full-swing on to CADding the sheet-metal version. We fired it up today:

Linear shooter, mini-CIM on first wheel, CIM on second, with AM pneumatic wheels. Estimated 30-40 foot travel at about 40%/60% on the two wheels, respectively, at 15-20 degrees. Definitely looking optimistic at this point! Thanks to all the teams that posted success with the paint buckets, can't beat $3 essential robot parts :rolleyes:

We are going for the back of the pyramid , we would like to make shots consistently from 13' to 25' straight line distance from the 3-goal.

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.

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?
 
Wow, I'm impressed! With our (4622's) first shooter we get maybe 8-9 feet at peak with 50% power and around 6 feet if it's 100% or 25% power which is really random but we're working on it and other shooter designs. We know the main issue with our shooter is the track it follows (the piece that helps to guide) is not at the right curve so once we get that fixed we'll probably be shooting further. Height is only around 5 feet, though.

We are shooting from anywhere on the field. We can shoot full court with about 80% accuracy with a speed of about 54 feet per second at around a 10 degree angle. Variable angle shooter allows for up close shooting. Mecanum drive. Current projected weight is 100 lbs. I'd post a video if I had one. I will asap! :cool:

Re: How far are people shooting?
 
Yeah, we have a shooter capable of longer than full court shots. We'll be able to change our shooter's angle for different distances as well. at 80% accuracy without speed control. Imagine what it will be with speed control. (;

Re: How far are people shooting?
 
We made a full court 3-pointer on Sunday (yes, yes, video) and went a miraculous 4 for 8 from the feeder station today. Unfortunately no video of that yet, but if we can't replicate it for the camera tomorrow it won't much matter that it happened today.

Generally though, we still intend to shoot from the back of the pyramid through the rungs (we ended the night hitting 12 in a row, and will occasionally miss 1 in 20). We can also hit from a few other places touching the pyramid. It's an arc shooter (<90deg) with a direct drive mini-CIM and a white HiGrip or a custom bike tread on a plaction wheel (we've had success with both--still deciding). 1/2+" compression, in and around a 20deg angle, depending on exactly how we feed into the wheel.
