To solve the problem of overheating the internal parts of the robot, engineers often develop complex and very expensive cooling system. Japanese researchers approached the problem creatively and have created a robot that … sweats. Progress on the modern technology market – it’s a battle between what is working well and what is the cheapest way to produce on an industrial scale. As a rule,wins recently. That is why scientists and created a robot, that is able to sweat.
One of the main challenges faced by engineers involved in robotics is to solve the system overheating. There are a number of active cooling systems that can solve this problem by pumping fluid through the refrigeration pipe systems, these “veins” and “artery” of the robot. However, it is not only difficult, but also expensiv. As an example, a cheaper but no less elegant solution, researchers from the Lab JSK Tokyo borrowed the concept of how a person sweats, to develop a own version of a cooling mechanism for Kengoro robot. 
Pot (in fact, ordinary water) drips on 108 engines in Kengoro, cooling them in the process of evaporation. Let it is not as efficient as the advanced and sophisticated cooling systems, such a thermal protection allows the robot model to be wrung out for 11 minutes. Only on one glass of water it is able to operate for 12 hours! However, the robot is not skin, and he has to sweat … to bones. To simulate sweating engineers with the help of 3D-printing technology and laser sintering (DMLS) created a two-layer porous aluminum frame, which is capable of optimally, preventing leaks, skip the liquid to cool.
