4 wheel steering/ Crab

[CaptainPlaid]

We developed a crab walk last year but ended up not using it. We used two drills for the drive and a globe to turn them. We put two bolts through the chain that turned them to contact limit switches. Then we set up two limit switches at the point where the wheels were turned 90 degrees to either side. We also set up the regular junk-from-the-kit servo but only used it to return to center. The resolution worked fine for this. I believe we had the two triggers set up to turn the wheels to either side and the top button for return to center. This way the driver has control for the full 180 degrees but can always get back to center if needed.
