A few paragraphs into the start the article literally says "The AWM can be manually driven, or it can operate in autonomous mode. The operator sets up autonomous operation by using a “Teaching” mode in which the mower is driven to create a mowing route map using a global navigation satellite system (GNSS)."
Right but all you need is a joystick/app to steer it not a whole seat. Having a seat seems like an admission the robotic part doesn't work very well.
Gotta record a route first then it does route playback
