Give me four hours with nothing to do and a couple of VEX kits. I'll give you a robot with four independent castor wheels - driven castor wheels, to be precise - that have variable position control.
+Brandon Young I made a team with four of my friends this year, we all had to pitch in 200+ dollars and thats just for the basics. Joining any form of team near you is so much cheaper
Well, that would make it crab drive, not swerve drive. The key difference is that swerve drive requires each wheel to tilt independently to allow complex maneuvers like more efficient turns and stuff of that nature; crab drive can only move left, right, up, and down but cannot turn while doing so.
