We incorporated rack-and-worm drive systems into both the shifting assembly and the steering. We are still working on mounting the drive motor for the steering. We had a lot of trouble at first, but then we realized that we could use an intermediary gear between the worm and the rack. This makes it a lot easier to drive the worm axle; we had been having trouble before because whatever gear we put on it would interfere with the rack. The system we’re working with now promises a lot of power in a compact space, and allows next to no flexing by the wheels.
We will be working again not this coming weekend, but the weekend after, and will hopefully finish up the steering then.
