VIDEO: Sweating robot efficiently cools itself like a human

When we use our muscles, they produce heat as a byproduct. When we use them a lot, we need to actively cool them, which is why we sweat. By sweating, we pump water out of our bodies, and as that water evaporates, it cools us down. Robots, especially dynamic robots like humanoids that place near-constant high torque demands on their motors, generate enough heat that it regularly becomes a major constraint on their performance. In this paper we propose a novel method to utilize the skeletal structure not only for supporting force but can also cool by using latent heat.
