alt Hacker NewsI kind of want to try something like this for garden weeding. Put a small spinning blade instead of a grabber arm on it. Computer vision can identify any weeds popping up and it'll go over and cut them before they get too big/woody for the blades. The challenge would be dodging taller plants and probably the forces that the blade would put on it.

I wonder if you could make it work vertically. It might ease the geometric challenges.
Naively, spraying targeted roundup from above or cutting a circle around the stem to kill roots kind of thing.
I think the project difficulty grows at least 10x with all the dust, insects wind, pollen in the air and whatnot even assuming you hide it for bad weather and you have secured very stable mount points. It sure would be cool though.
I am picturing a drone, one with the fan at the bottom :) OR one that can do a roadster maneuver at the right time.
Edit: Isn't there already one that Zap's weed with a laser?
