Re: Crab Drive
We have a lot of experience with crab drive and we've always set it up the same way: We use 2 joysticks. The right stick is used for normal tank-style controls, while the left stick can be moved left and right of center to cause the crab wheels to turn in that direction. We've found this quite effective.
Probably the most important piece of advice I can give for any teams considering using crab for the first time is this: you need practice. I don't care how good your drivers are at playing video games that are similar, it's different on the robot. You won't be able to take advantage of the capabilities of crab unless you practice, simple as that. So, get a prototype base up and running early in the build season for your drivers to practice with!
