11 disk auto.
Have both partners not preload any discs, then just drive down the center line picking up discs while shooting. The robot could be like 987, except with their shooter positioned so that it shoots perpendicular to pick up.

It sounds pretty pointless right? But remember that in quals you can get allied with robots who don't shoot very well (or at all).

EDIT: The robot would also need an uber-powerful drive train so that opponents who try to get in the way just get plowed through.

Has anyone seen 2474's pickup? It collects both forward and backward. The only issue is that it's a spatula/roller-style pickup, so a nine-disc would be extremely tight for time if you consider that it has to lift the discs up to it's shooter.
But I think with some programming magic and a rapid fire rate, it could be done.

Good catch - I think it was 550s. In my head I tend to sort motors into CIM/window/globe/other.

Re: Creating the perfect robot
 
Everyone's talking about the highest scoring robot being the "perfect" robot, except the only score that matters for winning is the alliance score. So by that the perfect robot is one that increases their alliance score the most, both for normal qualification and high scoring elimination matches. Then we get back to the robot that can carry 2 other robots to the top of the pyramid. It would have a flat top with a pull up ramp. It would have a fold out 2 stage corner climber (like 1334) with a shooter that folds up and down (like 3940). It could shoot 3 disks in autonomous, make 3 cycles and finally triple climb and dump.

At a regional it could score 164 points with 2 plowies(box bots). It shoots 3 off in auto (18), 3 cycles in teleop (36) and finally triple climb and dumps (30 x 3 + 20 = 110).

At iri we get paired with a robot that has a center line auto and one that has a seven disk auto. Now we have a 90 point auto mode. In teleop all 3 cycle and because two robots have ground intake they pick up the misses for 135 points. At last the carrier robot climbs with the colored disks and 2 other robots for 110 points. In total the alliance makes 335 points.

Now your saying 335 points is great but it is close to impossible. Lets say the alliance misses 3 disks in auto and makes 40 instead of 45 disks in teleop. That's more reasonable. The alliance still scores 168 and the world high score without penalties was 167.

Also you have one of the most memorable robots in the history of first and can claim the title of the Ultimate Ascent.

I have significant doubts any robot built to the specifications of Ultimate Ascent could achieve this task.

And especially not one built(mostly) in a 6-week build season.

Looks like this:

Fire your starting 3, possibly while dropping your pick up (which faces center field), and backing up toward the centerline discs.

Grab the centerline discs, and fire them as you drive all the way to the alliance wall with your pickup up.

Grab the forward and under-pyramid discs as you return to your starting position and fire them.

It'll be tight, but I'm pretty sure its possible with a robot that's designed for it.
We designed our offseason bot pretty much exactly along those lines. Stay tuned to hear it will end up working out.

Actually, all it needs are bars at the same height as the first rung of the pyramid so robots can latch on as they normally would. A fold out ramp would be very heavy, and probably less safe.

I wanna see someone pull this off. You would have to have a gearbox using 90% of the motors in the KOP for your lifter. Then you could maybe shift that gearbox to control the drivetrain, and then shift it to control the shooter.

That'd be awesome. Every mechanism on the robot runs off the same gearbox.
Lol.
But seriously I'd love to see a robot pull that off.

Ok, I understand the design, but how in the world does it fit in the 54" cylinder? I know it's in any orientation, but its still the 54" diameter x 84" length cylinder, and I just don't know how you could build a platform that would hold 2 other bots. The idea would also make me nervous, as if you fall, you're taking down 2 other bots that may have never even thought to design for taking a fall like that. An alliance would be destroyed. Not to mention packaging all the other mechanisms would likely be a nightmare.

Nonetheless, it would be awesome if someone were to pull it off. Totally would be THE bot of the year. It'd be sick.

Re: Creating the perfect robot
 
shifting swerve drive
under 30 in tall
extremely fast drive train that can push too
7-9 disc auto
469's collector
turret shooter with adjustable angle, has lift to raise to any height under max
shooter must be lowered to get discs off ground can raise, can get fed from feeder slot when raised
shooter faster than 67's and more accurate
ability to score from anywhere on the field at any time
collects any discs missed by opponents and scores them
arm attached to shooter lift, can climb corner or sides, inside or outside of pyramid
can climb and dump in under 6 seconds and then climb down to get rest of colored discs
can play defense with any time it has left

9*6=54
(45+15)*3=180
6*5=30
30

54+180+30+30=294
new world record by one robot

ps. it can also swim under water

What if it had a system of 2 shooters, so it could go through all the alliance's white Frisbees much more quickly? Then you have more time to do each of the other things on the list.
Or, just put your shooter's RPM at peak efficiency for whatever motor you are using. My team was shooting twice as fast at IRI because we switched from a CIM on our shooter to a pair of BB550s in a Cimulator box. It just so happens that the banebots+gearbox were near peak efficiency at the RPM we ran the CIM at, so we went from shooting about 1 disc/sec to 2.5 disc/sec.

Whoa, there, let's keep it within the realm of possibility! Update on the CAD: drive base is done, drive gearboxes stolen from 1477's CAD are in place. I will make custom ones once I finish the rest of the CAD.

They had by far the best spatula collector. It was the only one I saw that could collect from both directions, and one of the few that could be effectively used in teleop. What really bothered me, though, was that they didn't have a climb.

The platform idea is near impossible, but if you instead had two bars that stuck outside your bumper perimeter 30in off the ground for the other two robots to hang on (would require your partners to adjust their hangers) its feasible and I'm sure you could throw a very simple shooter that you could use in auto as well as make a few cycles before climbing for 30 with your partners.

Can I ask- do you think YOUR climber could lift three 120+ lb robots? It would have to be some massively powerful climber to achieve that.

Not as is. Only one CIM and the system was designed for lifting one 160lb robot not three. A 254 style that utilizes 6 cims could work.

Our style of climb also wouldn't work unless we figured out a way to shrink our partner's robots on the way up! :p

So a 6 CIM PTO 2170-style climb with two bars made for hanging somehow. That better be a stable climb. And then you're gonna put a shooter on it too?
Jeez.
