I was working on a two-motor drive design and was wondering yalls thoughts on whether this would be practical to save motors for other components here is the rough sketch [IMG_6798]

While chaining your drive wheels together is a good idea to keep them all powered, I would highly recommend 4 motor drive at a minimum for this years game. 4 motors to manipulate game objects is enough for almost all situations.

Though having 6 motors sounds good for the rest of your robot it is not the best idea, 4 motors are really good for any kind of robot so you can carry a good amount of weight and go over game obstacles. I really like the rough sketch though and it looks like a good idea, I might try to make somethin…

With a game that only has a few different moving parts, it’s not necessary to give four motors for all of the subsystems other than the drive. Most robots are going to be running 4 or 6 motor drive this year, because with the right design and planning, you can use a 1 or 2 motor launcher mechanism w…

With the four-motor drive would i still be able to use the chain with it or would that be unnecessary for 4 motors?

Not a good idea you will over heat superfast and you wo t uave any torquetopmay defense. I myself usea 6motor drive and am able to accomplish all of thetask besides expasnion with 2 motors

what cartridges are you using in your drive?

It really depends on where you decide to put the motors. If you have enough space to put the motors directly to the wheel, then you don’t have to use chain, but I would still recommend using either chain or gears to link the wheels together to maximize power to all the wheels. If you don’t have enou…

I use 600 cartrigies but i gear it down to 450rp. And i use 2.75in omnis. This gives a speed 9f 64in per second

If you are doing 4 motors for drive i would highly recomend 600 cartriges geared down 3:7(36:84) 257rpm on 4inch omnis(54ish inper sec) . If you need an example i can private message you one

This, and other building a quality drive posts by Xenon, are good references for anyone wanting to build a standard tank drive.
