i know that is a bad idea but imagine if someone showed up with that to worlds
I agree with you random man I donāt know. x drive could be very good this year due to its maneuverability and how it moves in general.
360 on 4in? are you using a 6 wheel layout of 4 because I dont think its possible for a 6 wheel layout.
What do you guys think about 450 on 2.75? I donāt have any experience when it comes to fast drivetrains (we ran 200 rpm on 4 inch last year 
).
Iām am pretty sure you could test thatā¦ rumor.
Good to see a sister team finally on the forums!
I have a idea lol, my school doesnāt have any pneumatics which alr sets us back by a huge mile. But i am planning to ask my trainer for pneumatics and if he could lend it to us. Ok so i came up with 2 ideas.
With pneumatics - 4m drive( 300rpm ) 3.25, 1m TIP intake, 2 pistons for mogo, 2m lift, 1m claw.
The claw helps to grab on 2 stakes and place them at higher stakes. 2m lift also js helps and prbly be a first level hang.
Without pneumatics - 4m drive ( 300rpm ) 3.25, 1m TIP intake, 1m mogo, 2m lift and 1m claw.
definitely lower slop. personally, iād say itās worth it to gear an x drive, 200 rpm 4 inch is bad space-wise.
too weak, you need 8m for that speed
is conveyor still feasible? I think not because the cap will prevent it from ever being effective. I want to know your guys thoughts on this
I personally think a convey is still practical. Even if it takes a bit force to get them in the mobile goal, there are many ways to get them in other than a pneumatic piston or something using a motor to push them down (from what Iāve heard).
What I was thinking, was a pivoted piece of c channel slanting down on top of the conveyer, which will pretty much force the ring to go in at an angle which will 100% get it inside.
Iām going to post this here because @9MotorGang has one of the best lists here so thank you. Personally I think they are rank with just a tad slower as better but still a great list
Yes, its still feasible just take a look at little wills bot: 44252A l Vex High Stakes RI1W reveal
Fourm users can also refer to Xenons post: Catalogue of Drive Gearings
To protect mobile goals in the corner kind of like the stacking game with boxes? IDK the name of the game sorry
Climbing kind of like the FRC game crescendo
Sounds good to me, but before buying pneumatics do consider their maxes. I measured exactly 30 successful extensions of a pneumatic piston without any weight on the end, and the last 9 or so of those were very sketchy. That was without weight. 30 could be more than enough extensions for a match, but that depends on the use.
I was planning on using a mecanum drive as well as using pneumatics attached to some metal pieces to lock the robot in place, by jamming the metal pieces into the ground (without tearing things) at such an angle that it requires a great deal of force to easily move the robot. This would be used for guarding positive/negative zones.
Are you talking of a kickstand? If so, I highly recomend looking at tipping point videos or a more recent video by FUN: 78181A Genesis l Pits & Pats l Vex Over Under
But, I dont reccomend mecanum drives because they take up a lot of space, need to have a very good center-of-gravity, and overall not good. Take a look at some recent topics on the home page and youll see some discuission about this.
Hope I helped you 
A flat plate that lifts the weight of the bot and has elastics or mesh for grip is the traditional way of doing this. Any spikey extension into the foam is likely going to break R6. I know I wouldnāt pass it at inspection.
