Re: please, talk to me about robot drive

Based on the numbers you presented, your prototype drivetrain is geared for about 10-11 feet per second. With only one CIM motor to drive each side, it's a little too fast and a little too weak to effectively turn that robot. I would suggest:

- adding a 2nd CIM motor
- reducing the speed (going to a larger gear reduction)
- going to a smaller wheel (effectively changing the ratio again)
- going to a less "grippy" wheel

Many teams try to design a single speed drivetrain for around 6-8fps. Multispeed bots will see ranges from 4-10fps. Some teams push for that 10-12fps, but they're typically running no less than 2 motors per side. Best of luck.
