"Peter Asaro, at Stanford University's Center for Internet and Society and a member of the International Committee on Robot Arms Control, is attending the talks. He says there is growing consensus that it is unacceptable for robots to kill people without human supervision.
Asaro believes that several countries, such as South Korea, whose statements were somewhat cautious at previous delegations, have become more outspoken in their opposition to autonomous weaponry.
"I think there is consensus around the fact that in its most extreme form you can't just have weapons out there without any kind of human supervision," says Asaro. "But there is still disagreement and work to be done on how do we define this as a legal term."
Meaningful human control, of course, has proved a notoriously difficult concept to agree on. "My own view is that the human should have meaningful control over an attack, whether in initiating it or being able to call it off after it has been initiated," says Asaro."
