From Japan, specifically from the University of Tokyo, a group of engineers has developed a robot, officially baptized with the name of kengoro, which stands out for something so common for a human as is the fact of sweating to cool down, except that this time this action is carried out to cool their engines in order to improve their performance in all aspects.
As one of those responsible for the project comments, the team has decided to be inspired by the natural cooling mechanism of humans to reproduce it in machines. Undoubtedly a very interesting measure, especially if we take into account that in humanoid robots the fact that the motors are continuously in motion makes them generate a lot of heat, something that ultimately affects their performance.
Kengoro is a humanoid robot capable of sweating to cool its engines.
Going into a little more detail, note that basically what this group of engineers have developed is a sweating system that can cool all the engines of the humanoid that you can see on the screen. As a detail, tell you that this unique solution at the same time that it is ideal for this prototype due to its architecture there was no room to add a traditional cooling system through a water circuit.
Faced with this problem and after long meetings, the team finally decided to use the metal structure of the robot's own skeleton as a system capable of supplying the cooling liquid. For this, this entire skeleton had to be manufactured with laser synthesized aluminum with permeable channels so that it can filter the water through the motor shell so that the motors can be cooled by evaporation.
