Just like our own muscle , when motors are combat-ready for long period of time , they take up to overheat . ordinarily , this requires some sort of cooling system , but these are often large and bulky , bound the construction of lightweight moveable robots . Now researchers in Japan havecome up with a novel solution . Meet Kengoro : the slightly creepy - bet humanoid robot that can sweat .
build by the University of Tokyo , Kengoro is a highly advanced slice of kit . power by more than 100 item-by-item motors , the robot is implausibly elastic , various , and firm . Butthe job aroseof how to stop the dozens of motors that power it from overheating , while preserve the amount of technical school on the automaton to a lower limit . commonly , the bread and butter anatomical structure ( or “ frame ” ) only dish the one role – keeping the golem upright . So the researcher decided to see if they could add another procedure to it , inspired by our very own cooling system of perspiration .
By make the skeleton out of laser - sintered aluminum powder , the team was ableto incisively controlthe structure of the frame . This basically involved using lasers to fuse the Al pulverization into a self-colored , meaning that it could be created as slow or as poriferous as the researchers required , and this was the headstone to the new cooling organization . Some arena were create with low permeableness , to give enduringness , while others were form with eminent permeableness with holes and tunnels , to transport the liquid .
Not only that , but the degree of permeability was also controlled , being less poriferous on the interior of the “ clappers ” and more holey on the outside . This have in mind the water motion in the focussing the researchers need , from inside to out , where it would vaporize and chill the robot , whilst preventing it from drool all over the floor . The water used in the system of rules was no average wiretap pee either , but deionized water , with just one cup of the stuff involve for Kengoro to run for about 12 hours without overheating .
This telling newfangled cooling system systemgives the bio - breathe in Kengoro far more survival than other robots of its variety . The robot can go for 11 bit flat doing pushup without the motivation to block , which is reasonably good going for a humanoid machine . It ’s surely only a matter of metre before it ’ll be pumping smoothing iron in the gymnasium .
