This year for high stakes I was thinking of making a 600 rpm 2.75 inch wheel drive with 6 dedicated motors. Additionally it would have a pto to 120 rpm for pushing robots. Would this be a feasible configuration as we would like to rush the mobile stake on the auton line.
Could be. It’s worth experimenting with.
Battling for goals will definitely be a big part of this years game and PTOing from an 8-motor to a 6-motor with another mechanism will probably be a pretty popular design this year.
Ultimately, it’s all just part of the engineering process, though. You identified a problem/goal, you’ve brainstormed, now you just gotta prototype.

But why though? Why risk an interaction when there is a mobile goal that is closer? Would one of you “goal rush” advocates explain the reasoning behind this?
I like the transmission idea though. Very innovative.
120 rpm is ridiculously slow. If you were to change the slower rpm to like 360 rpm, then yes it would be viable, but perhaps unnecessary/difficult, but at 120 rpm, any robot would be able to not get pushed by simply driving away from you.

I do not believe a transmission will be viable, transmissions are bulky and take up a lot of space, plus If you are low on air it could become stuck in a certains setting. Not to mention the added weight, pushing is not common enough to make a transmission useful, 600 rpm really isn’t needed to rush the goal as I doubt many teams will do that, however if you want to have more speed than a 450 for rushing you could use a rubber band accelerator like on 4082B Freedom gladiators tipping point bot. Just search up 4082B robot explanation and find the one from tipping point.
That entirely depends upon you, your strategy, and how you go about building it.
From a strategic standpoint, assuming this works out perfectly, I can definitely see the viability of this at a competition. Although not necessary, it would be a great option in case you find yourself attempting to dislodge an opponent from a corner modifier.
As for the mobile goal rush, it could be viable, but it entirely depends on your opponents. If they can’t descore, I would go rush the middle goal, fill it up with rings, and then drop it when driver starts and get the 2nd mobile goal on your alliance’s side.

We were thinking of getting that goal first and filling with rings within auton period and when the driving period occurs we get the closer goal to get an upper hand in the beginning of the match. Also I don’t think it will be heavily contested in the first few months in the game.
Though you made a valid point regarding the ability to match the speed of other robots with a lower rpm you can also try to pull goals out of other robots claws and the corners. Though what rpm would be the most ideal while still having some speed? 200rpm?
Hard to say. Experiment and you will probably figure that out
we just finished our version of the pto drive, it works great and even without any extra weight it can push our regionals robot, it also goes faster so you definitely could rush auton line, however, we are going for an easy winpoint.
Sounds great. Just wondering if you pto drive from 6-8 motors for example or is it a rpm switch Eg: 600rpm to 300rpm. And if so what ratio did you find works best?
