Neat. Might be good for a sizeable green house also. I doubt it would work for larger farms unless there was some way to make it mobile.
That's why I was thinking more along the lines of self-driving equipment for something like a 160 acre or larger far. Heck, current ag tractors are already practically self-driving with differential GPS. The most unreliable part of a modern tractor is the $10/hr illegal alien running it.
Make them self-driving, and you just need a mechanic with a tablet to monitor them.
Fly320s - on the complexity of setting it up, it seems like that's part of the prototyping demo in the video. I suspect the units they're selling will be fairly plug and play. As long as you decide what size plot you want, then it's just the initial setup. If you want to expand or move, then yeah, you've got a bit of extra work and calibrating to do.
