Hey, I would like to know what is the best drivetrain for a 15” robot for Vex U. Our team is training and we want to learn tips from you.
Thank you
It depends on the game some, but generally, teams almost always use 8+ motor drive. A lot of the best teams use custom omnis taking the rollers from regular omnis and 3d printing the plastic part either to get custom sized wheels or just for the aesthetic. Even more teams use 3d printed gears to get custom ratios. So last year, for our skills bot, I made custom 3.25" mechanum wheels that were about the same thickness as the Omni wheels and I used custom bearing to get 420 RPM. This also let me have a set of omnis in line with the mechanum wheels. Since it was only being used for skills and not for matches, we didn’t need to have as much pushing power so that one was only 6 motor drive.
To Summarize the big differences
- 8+ motors
- Custom Gear Ratios
- Custom Wheels
