Building rope structures with drones

Yes, another video…. Sorry Dad……
I sat enthralled for three minutes and twenty six seconds while I tried to wrap my tiny brain around the software required to get this job done.
Granted, there is a lot of behind the curtain processing going on, but even so…. its still some serious software chops to get these guys to not hit the rope.

Where is this going?
Hard to say, drones are getting a lot of flack here in the States, guys are doing really dumb things with them (flying near airports, over brush fires, in sports stadiums etc) and the public backlash is really mounting… case in point, this website is now a thing;

Ok, somehow I have got distracted from being amazed at a video to borderline philosophical musings about drones…..

Sorry about that.
