I’m running a 480rpm on 3.25” omni with gears 60 48 48 48 60. Originally I planned to put a 3” flex on the middle 48tooth gear but later realized it is too big (too close to the ground) and didn’t have great effect when going over the barrier. Does anyone have good suggestions about what I should put on the middle 48 tooth gear to optimize the ability to go over the barrier?

I dont know about if you have sleds or not, but it usually takes alot of torque to get over the bar effectiveley. 480 RPM sounds way too fast in my opinion. My team had a fairly small robot working at 400 on 3.25 wheels, but even then torque sometimes presented itself as an issue. I dont think the middle wheel is the issue, i think its the speed.

If your wheels are on the 60T gear and you add a wheel to the middle 48T gear, your middle wheel is going to be running at 600RPM while your two other wheels are running at 480RPM, assuming you have blue motors.

Its a 88w drive bot inspired by 9364H so I guess it will be all fine

Yeh I want a drive speed between 450 3.25and 600 2.75 to balance out speed and torque better on 88w drives

88w is enough, thanks for clarifying. Feel free to ignore my old post then.
I haven’t tried this, but you could add a triangle/rounded sled underneath the robot that would help “slide” the robot across the barrier and tip it in a favorable direction
Here’s a janky sketch:

So our old robot was a chassis with 2 sticks the sticks makes it go over sticks or sleds are the best also you have to have a good speed to not get stuck
I honestly think you should do 6 or 8 wheels so your motors don’t get tired out so easy.
