When muscles are used, heat is generated as a by-product of their operation. When we really exert ourselves, the body cools down by sweating. Sweating removes water from the body, and when the water evaporates, it cools us down. By evaporating, sweat removes a lot of heat from the body and thus participates in the regulation of body temperature. Robots, especially dynamic ones like the humanoid Kengoro, also generate a lot of heat due to their many motors and electronics, which is often the main problem of technological devices, as they tend to overheat, which reduces their capabilities. At Kengoro, the engineers have solved this so that if the robot is working at full steam and producing a lot of heat, the robot will 'heat' and thus dissipate the excess heat and consequently not overheat, so it can also do push-ups and do them as a joke more than you!
