I had assumed this was referring to street level flying drones.
replyLike you see in drone races. But with a little bomb attached.
Even with half life. That could be years. Depending on changes. Old neighborhoods probably haven't changed.. And, not sure I read that deal had a cutoff, or not. Could they continue getting updates. ?
If they are, then SLAM/object avoidance is pretty much the way forward.
replyThe issue you have there is you need a high shutter speed with no rolling shutter to get good reading.
