A new robotic hand can withstand being smashed by pistons or walloped with a hammer. It was designed to survive the trial-and-error interactions required to train AI robots
A new robot hand provides extremely fast and flexible finger movements, while also being tough enough to survive intense damage. That durability helps the hand, which is already being used in Google DeepMind’s robotics experiments, during the trial-and-error learning required to train artificial intelligence.
This latest robotic hand developed by the UK-based Shadow Robot Company can go from fully open to closed within 500 milliseconds and perform a fingertip pinch with up to 10 newtons of force. It can also withstand repeated punishment such as pistons punching the fingers from multiple angles or a person smashing the device with a hammer.
Each robotic finger has hundreds of sensors on its fingertips and dozens on the other finger segments. Tiny cameras focus on the inside surface of each robotic finger’s silicone skin – touching an object may deform the robotic skin, and this interior view can thus indicate the object’s hardness and shape.at the University of Oxford. “It’s also engineered to be easily fixable.”
Some research labs and companies beyond Google DeepMind may find the capable hand to be useful, says Posner. But it is likely to be expensive – Shadow Robot Company has not yet announced its price – and other researchers may prefer cheaper robotic hand options, even if they lack some or all of the sophisticated sensing and object-handling capabilities that the Shadow Hand combines in one package.
