I would recommend something similar to Chezy Drive. We've been using Chezy Drive for the past 3 years.

What is Chezy drive?

Its a modified arcade drive. They use 2 separate joysticks. One to control throttle, and one to control turning. Some math actually changes the turning ratio so the robot turns in smooth arcs instead of sharp corners like standard arcade drive would. This makes full speed sweeping turns much easier, which makes the robot more controllable.

Their implementation can be found here.

That is essentially what we use but I just called it halo drive. I might just implement the "smooth arc" changes to our drive though to see what that is like.

do you have video of the drive running?

Of our prototype drive, yes. Our video guy won't be able to render it immediately though :/

And just a linear drive is a bit to uncontrollable, so we are going to try to test out some different math functions for the different gears and see what handles the best.

How do you guys hold the wheels on to the shafts at the end? I'm designing a WCD for our team and was curious how other teams accomplished this.

Our team, and I'd imagine most teams, uses snap rings.

Really? That's what i have in the CAD now, but I was told that those might not hold up under the force of the wheel trying to push off the shaft. Any specific type? Thanks!

We use klip rings which are a brand name type ring. They are a special type of e-clip but easy to put on and take off with a screwdriver.
Here is the link to them:

They are rated for a lot of force, and unless the snap ring is damaged by deforming too much during installation (easy to avoid with proper snap ring pliers) they are plenty for the job.
