Just watched an interesting article on BBC Click about how Harper Adams University are using autonomous vehicles and drones to Plant, Manager and Harvest Crops autonomously.
The article shows then using Ardupilot and Mission Planners to control the vehicles.
The BBC link doesn’t work internationally but that can’t be helped. the Harper Adams University one is good to see. I might reach out to them to make sure they can find me in case they need help in the future.
