when you look when it's off the regloth, you can see them moving sort of.
when it's turning, the wheels moving and then you can sort of see them moving over the regloth.


it would help if the camera was closer so we could see it

also. if you look closely in the middle of the wheels, you can see the black part turning

That's a coaxial swerve drive, so each wheel is powered by a sprocket through the top and is able to be turned by a sprocket on the same axis. Here's a picture of a swerve module used by 148 last year, it should help you understand how they work. The small sprocket turns the whole module, and the large one is attached to the bevel gear by a shaft.

Just wondering, what do you guys use to attach the swerve modules and allow them to spin? (I.E. between the U bracket and the first sprocket in the picture) Turntables? Thrust bearings? This is the last major thing i don't understand about crab/swerve drive. Any help would be great.
