30pt climb under 15 seconds

Pictures? (nevermind, I really need to read the whole page before commenting...)

I feel like a good auto will be the key this year.

Our design does allow for 6 pts in auto - 3 discs into the lowest target.

Well, its worth as much as last year (Actually less because its 6,4,2 not 6,5,4) The exception is that the end game is more valuable this time around since one robot can score 30 points all by itself.

What makes people think that auton is more important than last year? (I ask because I dont remember people saying as much about auton last year)

Speed and space aside for a moment, how much out of the robot total weight do these 30 pt. climbers take? (only parts\mechanisms relevant in climbing)

I say because one robot can have a 7 disk auton. 7 disk in 3pt goal is 42 points and if you are that good of a shooter in auton then that translates over to teleop where you can probably dumb 3-5 loads in 3pt goal which is 36-60 points plus an easy 10 pt hang at the very least. That there is 88-112 points.

There were 5+ ball autonomous last year, sometimes even 6. 7 discs this year is hard, because you immediately limit your starting configuration to under 30in, then you have to vision target the Frisbees if you want any sort of constancy, have a variable angle shooter to shoot immediately, and do all this on 15 seconds

I believe it is easier in the fact that there is less of a variable in the form of counting on teams, 7 is hard but can be done, 9 takes too much time and you have to turn. This is all based on your robot though.

I thought what would be really neat is if a team got a running start at the bottommost rung, snagged it with a hook, then used their forward momentum to swing the robot all the way around to inverted to catch a hook on the next rung, release the first hook, and continue rotation until the robot is again upright and hanging from the first hook - sort of like one of those toys that gracefully tumble down a window in reverse. Running the numbers, you'd only have to be going about 13 mph to pull it off (assuming 100% efficiency), and it would look so totally awesome. Plus, way under 15 seconds.

if 25 can wheelie the co-op bridge in auton why not?

You might want to look into getting one of the older compressors. While they are heavier, I understand they're better rated for long duty cycles than the small ones.

Good luck, can't wait to see the video!

[CalTran]

We actually have two of the older compressors, and got the and one new off of FIRST choice. The reason we picked out was the thing is so much lighter than the other, at the cost of exactly what prevents this on the old design.

I guess that depends on how you set up your robot to shoot into the goal...we are planning to have it contact the pyramid lower rung, in a way that lets us shoot from the same spot consistently, no need for vision targets or variable shooter angle. This is a big help for autonomous...even though we're not planning to do it in auto. We'll let other teams show how it's done.

You can easily shoot from the same spot (Key/Fender anyone) but the trick to it is that you have to be shooting from that exact roughly the same spot. The multiball autonomous was "simple" because it was shoot two, straight back/ram bridge, straight forward while loading balls, shoot two+ from roughly the same spot. That gets more difficult this year because you could do start 3, forward 2, back shoot, BUT you'd have to go under the pyramid. It'd be simpler if you could shoot three, forward, shoot two from inside the pyramid for a 5 frisbee autonomous. 7 frisbee autonomous is trickier still, which is why I'm say it's more difficult. Compressing all this into 15 seconds is exponentially more difficult.

I think you're forgetting the fact that there are three robots on an alliance. The game can't support three awesome shooters, just like last year. I know if we are fortunate enough to seed first in our regionals, and there is a RELIABLE 30 point climber that can play defense and (maybe) dump discs in the lowest goal, that they would be our first pick. Who would you pick? A robot who can climb AND drive around to play defense, or a robot who can just drive around?

Just a note to people designing 30 point climbers and plan to dumb in the low goal. Make it a priority to pick those discs up off of the floor. There are going to lots of discs on the floor from when (yes... when) the powerful shooting teams miss their shots. It's also a very good strategy to rob discs from the opposite side to disable an opponent who can pick up off of the floor. Trips back and forth from the feeding station are going to KILL your efficiency (think 2011) so they'll also kill your opponent's efficiency.
