pic: 4143 differential swerve concept

This is an interesting concept for FRC, and one that has seen use in plenty of industrial systems.

For FRC, your next iteration is to make it ...


... triple coaxial

For a modelling proof, there are some really nice features (symmetry, use of TB Nano, low custom part count) in this design.

If you didn't wamt steering motors on the modules, couldn't you just put a gearbox in the middle and belt-drive it to each module? Saves motors and weight.

Say this was geared for 10ft/s and the two wheels on the module were 2 inches apart on center. Not taking friction into account, and assuming there's enough torque to turn the module, the module would be capable of rotating at approximately 1200rpm.

This is awesome. Always impressed with what 4143 comes up with!

I'm afraid if the motor allowance rules remain as they were last year, you'd only be able to make 3 of these modules.

If at FIRST you want to succeed, try triangle robot?
