-Because the Circular Shooter design only required a single wheel to power (whereas most linear shooters use 2+), the design was just as effective when shooting, but required relatively fewer resources.

118 actually has a foam wheel linear shooter, with a small back wheel and a large front wheel:

We (3476) used a curved single-wheel shooter. Shooting speed, accuracy, and distance for the frisbees are a boon with its design.

My eyes must not be what they used to be Standing next to 118 in queue their shooter looked rather curved to me. It must just've been everything around it that made it look different to me.

The to-do list right now is:
-Add the ladder climbing design, like 254 and 1986 (ish) have. Anyone else want to submit a team for this category?
-The robot superstructure used by the likes of 33, 1538 and 469 (a large, wide rotating arm that acted as intake and shooter) doesn't really have a specific category. I guess it'll get it's own little section.
-A little bit on feeder station loaders. Any teams you see have a notable feeder station loader? Most teams just had a long chute that the discs dropped to.
-Changing the embarrassing mistake of a section called "Ball Acquisition System"
-Still looking for suggestions for drive systems. Anybody?

I'm short on time now but I will be able to update this, hopefully tomorrow.

Regards,

Kicky roller:
3476 and 696 used this design to acquire frisbees.
As opposed to the spatula (1986) or polycarb/roller (987, 1538), this design doesn't have anything dragging on the ground in order to pickup disks. We have a small belt-driven roller wrapped in silicon tape that "kicks" the frisbee from the ground, while rollers on the other end of the frisbee pull it onto the roller while keeping just the tip of the frisbee pressed against the floor. Here is a video of a prototype I made of this design: http://youtu.be/bhP0oiJWbI8
And a CAD screenshot:

I want to second 1503's slingshot cannon as a "Best design" for its uniqueness and surprising effectiveness of use.

For the drive, how about 254's 6 CIM shifting with power take off for the climber?

[MARS_James]

I think my team and several others had what I would call a hybrid shooter design, not quite curve not quite linear I will attach 2 pics that showcase what I am talking about. It allowed for the increase contact time and single motor of curved shooters and the small packaging of the linear shooters. I think it served us well.

How has the awesome circle bot from 3574 not been brought up yet, getting a close up look at it as an alliance partner on Newton was awesome.

254 had this too

.

20 had a similar design, but we always categorized it in the category of circular shooter, just with a different angle.

In addition, to add to the climbing- the basic pneumatic pullup. The advantages of it were that it could pull up even after the match ended, and it was often faster than the passive, requiring no speed when coming into the bar, and it never got caught on a bumper like some passive hangers did. 20 had this, as well as many other teams. I know that 228, GUS did, but I can't recall others off the top of my head.

In addition, teams like 2791 and 33 that used their adjustable shooter angle to hang as well deserve a mention in that category.

Possibly an "other" category for innovative shooters like 1503's catapult and 2337's double-barreled shooter.

As far as shooters go, I feel as if ours is possibly worth discussion. At 40% power we could make it across the field at the right shooting angle. We have not done a pure distance test yet. We were also able to shoot with fairly high accuracy at the 3pt goal. Our 7 lb flywheel was the most unique part of it.

[Bwalker]

I'd like to nominate our team's, 1448, robot for our 30pt corner climbing mechanism. Our rack and pinion system for extended our climbing arms is the only I know of for any robot this year, definitely at championships. In addition our climbing mechanism never failed once it began, since it was completely autonomous.

Is it necessary to have the intake push it into the roller? Wouldn't it also work just by driving into the frisbees?

Enjoy,
Leeland

Drive
- Most Innovative Designs (designs such as our butterfly drive)
- Best use of (tank, mecanum, swerve, slide, holonomic, omni, traction)
Also, check here for additional comments on drives: http://www.chiefdelphi.com/forums/sh...d.php?t=116559

Shooters
- Best Full Court Shooter
- Most Innovative Shooter Design (were there any w/o wheels?)

Climbing
- Best Climber using Stored Energy (Gas Shocks, etc)
We attempted this once, twice, and still couldn't safely get it on our third try.

Pickup
- Best Vacum Pickup System
- Best "Spatula" Pickup System (such as 2175's & ours)
- Most Innovative Pickup System

Auton
- Best Auton (Those teams in the 7 disk auton club?) & maybe recognize 5 & 6 disk auton shooters as well.

Robot
- Most Innovative Design (kinda like the engineering excellence award, but a robot that would fall in/ be considered for the most categories?)
- Most Creative Robot Design (Anvil's anyone?

[Shane1302]

Best full court shooter i say has to go to 303, we competed with them and against them in MAR, they were great to have as an alliance partner! I was so happy to see them go to Einstein! Although we defended them with a single pool noodle....

[JB987]

How about effective utilization of a turret with target lock? A limited club for sure...

[Procolsaurus]

Who had that very thin, long FCS? I think I saw them on the MSC webcast. Wish I could remember more.
