I would love to get some opinions on drivetrain speeds.
We have a basic understanding of gear ratios, driving gear vs driven gear etc. When we apply this theory to a drivetrain however we mainly get omni wheels that are spinning way to fast to get any traction, so even basic things like pushing an H-drive wheel in the center if it isn’t perfectly placed on a black bi directional.
I would assume that it would be one to one. However, that’s edr where people are competing against each other. Since u work together in iq, I would suggest gearing speed 3:1. You don’t need to care about the amount of torque on the chassis and 3:1 generally doesn’t have a lot of slip.
Our IQ team has always used omni wheels ever since they got started with Ringmaster and haven’t had that issue. Our robot last year started out 1:1, then moved to 3:2, then ended up with 2:1.
That’s all subjective and relative. It’s really up to your drivers. Once they get used to the robot going a certain speed, it becomes normal. When our team moved to 2:1 all the drivers noticed the speed increase. But as they got used to it, that became normal speed.
I would suggest a 3:2 (gears will be offset) and gradually move up as the drivers get used to it over the season.
I would build the drivetrain with a 1:1 gear ratio. Then via programming start at say 50% speed and as drivers get better increase that limit. If they get to 100% speed and they feel it is too slow, then start experimenting with other gear ratios
