Will this drivetrain work? It is 600 rpm motors geared down to 480 by 48:60 gear ratio. 6 wheels, omni on the outer wheels, traction in the middle. My teammate told me it wouldn’t be able to move based on static friction. It should move at 81.681 in/sec based on my calcs tho. We are a new team so any help would be appriciated before we buy the new gears.

I don’t see why it wouldn’t work. idk what your teammate means when they say static friction, I don’t see how that applies here. Just remember to box your screws, keep the drivetrain square, etc, and it should be fine unless I’m missing something

that would work perfectly fine I’m just wondering are those wheels screw jointed if you probably would want to for better fricton

As long as it is six motor and is built right it will drive, might be too fast for a new team but if you build and drive it go ahead

That drive looks extremely good, I don’t see any reason why it wouldn’t be able to move.

Hey are screw jointed, but with plastic circular inserts because the brass ones are out of stock

I’m just wondering do you have the new claw kit because the spacers on those fit perfectly inside the wheels and are very low friction
I’ll check when we get back to school.
not sure why this wouldn’t work, it looks robust as well so good on you for that (very advanced for a new team imho, nice work!)
This looks really good for a new team. One thing you could add is a c channel brace running from the inside ends of your back funnel. This channel helps the goal drive onto the robot for clamping.

We have made revisions to the whole chassis, adding a high strength axle in the back like you mentioned, pushing the forward bracing forward, flipping the back c channel brace upwards and a little more. It’s all coming together now, thank you for your help.

That is a very fast drive. Not bad or this game necessarily but it will definitely take a lot of practice to control well.

Now that you have it built, I would advise that you see what rpm the motors are turning at during normal operation. Using the 600 rpm cartridges will sacrifice torque (pushing ability) to give a high top end speed. Also, if you are consistently running the motors at low speeds you sacrifice efficiency and can get motor overheating.
You can use the device menu to show what rpm the motors turn at. Maybe there is a way to store this data on the brain. If not, then tape a cell phone camera to record the display, or time test on a measured flat distance and compare to your calculation. If you can’t achieve near 600 rpm on the motors when it runs at full speed, this is a good indication that you are geared too high.
