After getting home, I couldn’t help but try out this concept in Inventor. I just had to know if it worked. After 6 hours in CAD (now at 1:45 AM after kickoff day), I think it’s working, and we can finish the model and produce this. Definitely some fun machining involved, but more design work to do first. I’ll let the students take it from here. Large steering gear is 84T. Drive gearing is 30:50. Wheel is 3 inch diameter.
