52670761 story Robots Can Learn To Hold Knives — and Not Stab Humans 104 Posted by Soulskill on Tuesday November 05, 2013 @10:05PM from the never-bring-a-knife-to-a-robot-fight dept. aurtherdent2000 writes "We humans enjoy not having knives inside of us. Robots don't know this (Three Laws be damned). Therefore, it's important for humans to explain this information to robots using careful training. Researchers at Cornell University are developing a co-active learning method, where humans can correct a robot's motions, showing it how to properly use objects such as knives. They use it for a robot performing grocery checkout tasks."
