I’m interested in creating a 1/8 scale application for an autonomous vehicle setup. Essentially, I would like to define a specified area by gps coordinates and have the vehicle drive in a grid pattern once every 2 hours and then park in a specified location. The idea is that once I have the 1/8th scale rover running in the specified manner, I would find some way to outfit a full size driving range cart to do the same. Eliminating the need for a driver.
for a little background regarding my experience with ardupilot:
I have built a few quadcopter. Both running on apm 2.6 and pixhawk 2.4.8. I use mission planner in windows 10 and have successfully flown autonomous planned missions. I’m assuming that setting up a rover to do what I’d like shouldn’t be all that different but since I have never used an apm or pixhawk to operate a rover, I thought it would be best to chime in on the forum and see if anyone has any advice that could help me avoid potential pitfalls.
Also, I’m still a ways off but at some point if I’m going to try to get this working in a full scale golf cart. Does anyone know about a servo that would be powerful enough to steer the wheel of a golf cart? And what setting up such a powerful servo would entail?
You should read the blog post of Matthew Reimer who has equipped his full size tractor with Ardupilot and has solved the steering issue. If I remember well , he avoided to steer the actual wheel with a servo (too imprecise), but rather interfaced the hydraulic steering somehow, with position feedback to avoid oscillations.
