Call to ban killer robots in wars
A group of scientists has called for a ban on the development of weapons controlled by artificial intelligence (AI).
It says that autonomous weapons may malfunction in unpredictable ways and kill innocent people.
Ethics experts also argue that it is a moral step too far for AI systems to kill without any human intervention.
The comments were made at in Washington DC.
Human Rights Watch (HRW) is one of the 89 non-governmental organisations from 50 countries that have formed the Campaign to Stop Killer Robots, to press for an international treaty.
Among those leading efforts for the worldwide ban is HRW's Mary Wareham.
"We are not talking about walking, talking terminator robots that are about to take over the world; what we are concerned about is much more imminent: conventional weapons systems with autonomy," she told BBC News.
"They are beginning to creep in. Drones are the obvious example, but there are also military aircraft that take off, fly and land on their own; robotic sentries that can identify movement. These are precursors to autonomous weapons."
Ryan Gariepy, chief technological officer at Clearpath Robotics, backs the ban proposal.
His company takes military contracts, but it has denounced AI systems for warfare and stated that it would not develop them.
