This is RoboGlove. It's like a Power Loader from Alien, but for your hand. It wraps around your hand, greatly enhancing your grip strength. General Motors, which is developing the technology, is being quiet about precisely what it can do. But we know that the aim is to make it powerful for heavy tasks, yett remain sensitive for gentle ones. Wired reports:
GM’s now working with Swedish med-tech company Bioservo to adapt the Robonaut’s grip to gloves. Pressure sensors and actuators mimic nerves and muscles, so the glove knows when the hand inside is picking something up. It’s gentle enough to handle eggs but firm enough to maintain a strong grip, so you aren’t wasting energy holding your hammer.
