Amazon said it has made a "fundamental leap forward in robotics" after developing a robot with a sense of touch that will be capable of grabbing about three-quarters of the items in its vast warehouses. Vulcan – which launches at the US firm's "Delivering the Future" event in Dortmund, Germany, on Wednesday and is to be deployed around the world in the next few years – is designed to help humans sort items for storage and then prepare them for delivery as the latest in a suite of robots which have an ever-growing role in the online retailer's extensive operation. Aaron Parness, Amazon's director of robotics, described Vulcan as a "fundamental leap forward in robotics. It's not just seeing the world, it's feeling it, enabling capabilities that were impossible for Amazon robots until now." The robots will be able to identify objects by touch using AI to work out what they can and can't handle and figuring out how best to pick them up.
