Researchers Create Muscles for Robots

National University of Singapore researchers have developed artificial muscles that are strong enough to help power a robot. The muscles, created from electromechanically-active polymer materials, can carry 80 times their own weight and can extend to five times their original length when carrying a load. How much a muscle can extend contributes to its efficiency. In this case, the researchers say it means it could perform a wider range of operations while carrying heavy loads. Conventional robotic musculature can carry only half its own weight and extend to only three times its original length. And as the new artificial muscles work, contracting and expanding, the energy created could propel the robot by converting the mechanical energy into electrical energy.  (PhysOrg)(National University of Singapore)
