Scientists Have Built Robot Muscles That Can Lift 1,000 Times Their Own Weight - Slashdot

An anonymous reader quotes a report from Quartz: Researchers at Harvard's Wyss Institute and MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) announced today (Nov. 27) that they've created robotic "muscles" that can lift up to 1,000 times their own weight. The simple objects are constructed out of metal or plastic "skeletons" that are covered in either a liquid or air, and then sealed in plastic or fabric "skins." The muscle pulls taught when a vacuum is created inside the skin, and goes slack when the vacuum is released. By folding the skeletons in different ways, the vacuum can pull the muscle in different directions. "Vacuum-based muscles have a lower risk of rupture, failure, and damage, and they don't expand when they're operating, so you can integrate them into closer-fitting robots on the human body," Daniel Vogt, a research engineer at the Wyss Institute, said in a release.

These new structures are also surprisingly cheap. As they don't...(continued)
