Needs some programmers to do the dirty work..With 3D printing and CNC you use Gcode..Wonder if same sort of software could be done with Drones..Unhook
from power,start rotors,take off to Point A,B,C,D at GPS coordinates then land and repower.
Anticollision hardware just get all the good bits out of a Roomba..
The Russians claim they have a cargo drone that can fly 350 km, carry 400 kg of payload and has an 8 hour flight time. The drone uses gasoline rather
than aviation fuel and the makers claim the drone will have 1/5 to 1/10 the operating cost of a helicopter.
