Researchers at Harvard and MIT universities have created robotic muscles that can lift up to 1,000 times their own weight.
According to Quartz, the muscles are made of metal and plastic, are covered in liquid or air, and then sealed in a special fabric skin.
“The muscle pulls taught when a vacuum is created inside the skin, and goes slack when the vacuum is released,” stated the report.
“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,” said Harvard University.
The researchers said the robot muscles are cheap to build – a single muscle costs $1 and takes 10 minutes to construct. This excludes the price of the mechanism which creates the required vacuum.
