JSK robotics experts at the University of Tokyo have developed a humanoid robot with a unique sweating mechanism. Kengoro - weighs 56 kg, is built on a 1.7 m high aluminum frame and has 108 electric motors that need to be cooled. To do this, using a 3D printer, they printed parts of the robot's skeleton with microchannels inside, water circulates through them and cools the structure. For one day of work, the robot takes half a glass of deionized water.
Thanks to this system, Kengoro is able to perform intense loads, for example, push up from the floor for 11 minutes in a row without the motors failing due to overheating.
