[Zeta]

Considering most regional tournaments are finishing up, what plans does everyone have for worlds?

Drive:

• traditional
• Strafing

Tray:

• 6-9 cubes
• 9-12 cubes
• 13 or above

Intakes:

• Normal
• China
• Other

Cube lock?

• Yes
• No

[trontech569]

Who says it has to be a traybot?
But yeah, I get that traybot is by far the majority.

[Peter_977Z]

I personally prefer normal drive over strafing because of motor limits. Every team deserves a 4 motor drive, leaving 4 motors for the mechanisms. Dedicating one of these motors to strafe means you sacrifice a lift, which is important for towering. The other alterenative, a 2 motor drive with a strafe motor, leaves your drive too weak IMO for playing any defense.

Mecanum wheels exist

[gilmorkn472]

As do x-drives. They are also 4 motor drives that can strafe.

Edit: Made it a little easier to tell what the polls are for

I might add more later if I can think of anything.

[ThirdDegree]

Sorry for the self-plug but here’s a similar post from earlier this year that might be relevant

Perfecting Goofy Polls

Just a general purpose post to spot trends in building choices and highlight the most commonly used strategies. If you don’t have a goofy style robot, please refrain from inputting data. Although some information might translate to other designs, I’d like to keep this focused. Goofy style robots are as follows 4m tank drive, 2m intake roller system, 1m tilting mechanism, 1m lift. Ratio used on two (or mini-4) bar lift poll Sprocket size and motor rpm of intake rollers poll Type of roller p…

What’s a china intake, and what’s a normal intake?

[trontech569]

China intake is the intake design with two sprockets at different heights with separate treads. The front part is for picking up cubes and the back is more for compression. Normal intake is just two sprockets with the same tread.
If my explanation makes no sense, sorry, I am a programmer.

[Zeldaa]

That’s a normal intake,
and those are Chinese intakes.
(Not my pictures)

[Riptide]

I don’t think those are chintakes, traditional chintakes have 100 rpm back rollers and 166 rpm front rollers and the rollers are geared together. Obviously you can make the intake a little different and still call it a chintake, but I’d say that’s more like a normal intake with just separate rollers at different heights.

[Navs14]

What are the chances of an external getting to round robin?

[Railgunawesome]

I think what differs a China take from a normal intake is the fact that each sprocket on the chinatake had it’s own tread, while normal intakes have both sprockets share the same tread.
After all, if I made a chinatake but both sprockets were the same speed, would it make sense to call it a normal intake?

[Riptide]

I would probably consider it a cross between the two because what makes the chintake special is the fact that the rollers spin at different speeds. When people ask “what is the advantage of a chintake over a normal intake” people normally say “It prevents chain breakage and allows for cubes to be processed faster”. If the sprockets spin at the same speed then the intake would have the same speed as a normal intake but with the added benefit of no chain breakage. If the chintake was just a normal intake with separated rollers it probably would not be such a big deal and it probably wouldn’t be special enough to dub it “the chintake”.

[Doctortictac]

Hey, that’s me!
I used a variation of them on my old robot. China intakes are geared together, and use standoffs for the attachment of the lower staggered sprocket. Those were… an interesting variation to say the least… so was that robot.

[Zeldaa]

Responding to this again (found a better representation of Chinese intakes). Hopefully this is more helpful than the previous picture.
Again, not my picture, not my bot.

[Sam_9364E]

Seeing the poll about how many cubes you can stack, I wanted to get a little more specific.

How many cubes should you be ABLE to stack?

• 8
• 9
• 10
• 11
• 12
• 13

On the other hand, say you could stack 13-14, how many would you actually stack in a normal qualification match against decent opponents?

• 8
• 9
• 10
• 11
• 12
• 13

[DrewWHOOP]

Cube lock is overrated. There are other designs that accomolish the same affect, but better.

[ThirdDegree]

Care to elaborate? I’d tend to disagree.
