With the advent of new multicopter's like the Lily (https://www.youtube.com/watch?t=65&v=4vGcH0Bk3hg) which is designed specifically for completely autonomous flight without a traditional R/C has anyone considered who's responsible for the aircraft, say in the case it flies into a person or damages property?
Whilst the ability to do "follow me" isn't new, normally there still is a person with an R/C and that person switches on the follow me/auto mode, and can disable follow me/auto and assume control at anytime.
However in the case of something like a Lily, there is no R/C, just a follow me transmitter. Looking at two scenarios, first one a person who owns the drone is filming them self kayaking down a river and whilst the drone is tracking the person it flies into a person standing on the bank. Is the person wearing the follow me module liable or is the manufacturer liable?
In a second scenario, the person who owns the drone rocks up at the kayaking event, and wants to film a competitor, they give the follow me model to the kayaker, and they throw the Lily into the air and it autonomously follows the kayaker, and hits a spectator standing on the river bank. Who's liable? The manufacturer? The Kayaker, or the owner of the drone?
I'm not sure there's an answer to this (yet) but it's probably worth having a discussion as I am sure there will be differences in opinion.
