Robot hand approaches human-like dexterity with new visual-tactile training

Human hands are a wonder of nature and unmatched in the animal kingdom. They can twist caps, flick switches, handle tiny objects with ease, and perform thousands of tasks every day. Robot hands struggle to keep up. They typically miss the sense of touch, can't move many fingers at once, and lose track of what they are holding when their fingers block their camera's view. Scientists have now developed a smarter way to train a robot's brain to give its hands human-like dexterity.
