Welcome to Chief Delphi!

The dimensions you want can be found here. For example, the High Goal dimensions are shown on sheet 69. Looks like it is about 22 inches deep.

Correction, per the Side, High Goal Basket drawing GE-13077 on sheet 135 of the set linked above, the depth is about 20 inches.

Look in the field drawings: it should give you all the dimensions you want.

Also, I find it kind of ironic how they called it "Ultimate" Ascent and it's actually more like disc golf than ultimate..

thank you very much, another thing, each alliance starts with 45 white discs, and there are two spots for each alliance to feed into the field from. do you completely decide which feeder station you want the discs to start at? as in, can you have all 45 at the station which also has the 1 point goal?

Sigh, did not think I would be digging through my senior design project papers tonight (As an aside this is quite humbling, I recommend to anyone who has already graduated college!)


From what I remember, our frisbee launcher was consistent to within +- 3 inches at 30 feet distance between 3 and 10 feet off the ground (when shot from around 3 feet). We used an 11 inch wheel connected to a cim motor that was spinning at 1000 rpm, and we'd put in a new frisbee in each time it was back up at 1000, which was within 2-3 seconds. The keys were putting a groove into the spinning wheel to grab the frisbee, covering the wheel with rubber foam, and then having a rigid outside wall with a straight path at the end, so that the frisbee would go straight when it left the launcher.

I'll now have to dig through our derivation of equations, but from what I remember it's not physically difficult to build a good launcher, the difficult parts are 1.) getting frisbees into the launcher, 2.) getting the software to aim it.

^Excellent post, Joe! Thank you!

Some follow up questions -- (1) what material did you use for the wheel? (2) how thick was it? (3) would you foresee any problems using a smaller wheel diameter and higher RPM, so that the speed at the contact point is the same?

Can Human Players score COLORED disc during the last 30 seconds into the tower for 5 points? I'm not sure if this was already asked

I think Frisbee Frolic would have been a better name.

Nah, field reset will still be trying to find the 117th and 118th discs - it'll be their fault.

Also refs will delay things as we carefully determine the exact heights of the lowest part of each robot.

The new radios had better sync up pretty fast, or we've no hope of hitting 7 minute game cycles.

I hadn't even considered the complications of resetting the field with this year's game. Lol sounds like a mess!

How is field reset going to get the disks down out of the tower goals (or even the high goals)? Is there some trick to it I'm not seeing?

Where can i get the RobotBuilder Program?

I would imagine that there is probably some release that kinda just drops them from underneath or something to that effect. If they are aiming for 7 minute turnarounds, there is no way that field reset is going to be climbing up there each match. That's 10' off the ground!

Remember, the 1 pt goal next to the 3-feeder wall is your opponent's. Be careful when looking at colors. From the driver's point of view, you get fed neat you, and your tower and goals are on the far end of the field. Also remember that your driver needs to look through two pyramids to see the goals on the far end.

While there are rules about team members climbing on the PYRAMID, I don't recall seeing anything about field personnel not being allowed to ascend the PYRAMID...

I imagine they have an easy way to retrieve the discs that does not involve having to leave the ground. At least via the PYRAMID.

It's provided as part of your programming language's update package. For C++, you'll find it in C:\Wind River\WPILib after running the WPILib update

Looking at the kickoff pictures, it looks like the bottom of the goal can be pushed upward such that all the discs fall out of the main opening of the goal
