Tetsuya Ogata and colleagues at Japan's Waseda University have taught an artificial intelligence-powered robot to tie knots around a box using just two fingers on each hand.

The team first directed a two-armed robot via remote control to manually knot a piece of rope dozens of times, then combined data recorded by the arms with information from an overhead camera and proximity sensors on the fingers; half the rope was colored red and the other half blue to aid identification.

The Waseda researchers used the combined data to train a neural network to replicate the task, and the robot was 95% successful in tying a bowknot with the colored rope, and 90% successful with a white rope for which it was not trained.
