According to foreign media reports, robots can now do many things like humans. Japanese researchers have recently achieved a new milestone: the development of sweaty robots - Kengoro (腱 郎), which can help the robot to maintain "fresh" and Efficient. 
This facial can be used for expressions ~~~ This 1.7 meters tall, weighing 56 kg of Kengoro is very complicated. It has many hydraulic transmission structures, circuit systems, and controllers. There are 108 motors in the whole body, 114 degrees of freedom! This statement does not allow you to intuitively feel the abuse of this robot, then we compare it, we know that the Google robot Atlas has only 28 degrees of freedom. Make a push-up to use almost any degree of freedom
The easiest way to test is to make the robot push-ups! Although many robots can do push-ups, they can do 11 minutes in a row and the motor is working properly. The heat is very good. At present there is only one Kengoro!
Having said this, then there is a serious problem! With 114 degrees of freedom, at least hundreds of motors are needed. How to cool the hundreds of motors! That is what we said above "perspiration"! This study won the IROS 2016 - Best Application Paper Award (2016 Best Application Award)
One of the biggest challenges faced by researchers during the development of robots is overheating. Overheating will affect the robot's efficiency and increase its chance of permanent damage. Kengoro does not have the extra space to place a fan radiator or water-cooled pipe. If you want to place a load that is bound to be another large pile, reduce the flexibility of the robot. However, according to the existing structure of the robot to solve the problem of heat, R & D personnel think of letting water seep from the metal skeleton near the motor, the principle of volatilization to take away the heat generated by the motor. Just like human perspiration! Clever ~~ And this exuded metal skeleton relies on laser sintering technology (sintering of powder compacts with a laser as a heat source). By changing the energy density of the laser during processing, it is possible to control the manufacturing of the metal skeleton. Bones have different permeabilities. Areas with poor permeability are very tight. Permeable areas are porous.
This is a passive method of cooling. It is not as good as the water-cooled equipment, but it is three times more effective than air-cooling. This kind of "perspiration" consumes a lot of water. Like humans, a glass of water can operate for a long time. Human beings are approaching God, although far, far away...
Some people may ask, what's the use of robots to do this? This robot is actually the best carrier for brain research. It can help analyze how brain signals control body muscles. In addition, it can also engage in high-risk work, such as hazardous chemical experiments, car crash experiments, etc...
