Nice setup!

The trailing arm that I first designed looked like the attached diagram.

I'm thinking if I replaced the spring (green texture) with a cylinder, the structure would have been more rigid and the wheel would not have lifted when moving left.

The other option would be to raise and lower a larger structure like dradel's post.

We did an H-drive in 2011 with a lot of success (won a district, made it to Einstein). We did not actuate it, but it was on a swing arm and loaded with a gas strut. We sized the gas strut such that in the normal position it applied a force of approximately 1/5 of the robot weight on sideways wheel.
