3D-Printed Sweating Robot Muscle

One of the hurdles for making enduring, adaptable, and agile robots is managing the robots’ internal temperature. If the high-torque-density motors and exothermic engines that power a robot overheat, the robot will cease to operate. This is a particular issue for soft robots made of synthetic materials. While more flexible, they hold their heat unlike metals, which dissipate heat quickly. An internal cooling technology, such as a fan, may not be much help because it would take up space inside the robot and add weight.
