Experts Warn World Leaders: Killer Robots an Imminent Threat
World leaders need to take the threat of killer robots seriously, according to a warning delivered by a group of experts to the World Economic Forum in Davos, Switzerland, last week.
The military could use killer robots to track down and kill people without being guided by human beings.
Those robots don't exist yet, but the technology to build them is being developed in countries around the world.
Some could be human or animal-sized, or extremely tiny - the size of an insect - capable of moving exceedingly fast.
Experts warn they could be as deadly as nuclear weapons and need to be regulated now before an arms race begins and to keep them out of the hands of terrorists.
