What did they do?

A team of re­searchers at the Uni­ver­sity of Tokyo have cre­ated Ken­goro, a hu­manoid ro­bot that ‘sweats’ to cool it­self down when com­plet­ing a work­out con­sist­ing of push-ups, sit-ups and pull-ups.

Why did they do that?

The ro­bot is de­signed to have anatom­i­cally cor­rect mus­cu­loskele­tal struc­tures closely re­sem­bling those of hu­mans. How­ever, the re­searchers ini­tially had difficulty in pre­vent­ing Ken­goro’s com­plex ma­chin­ery from over­heat­ing when per­form­ing com­plex ac­tions. The so­lu­tion was to punch a net­work of tiny holes in the ro­bot’s frame and use it to carry wa­ter around the var­i­ous struc­tures. As the ro­bot heats up, the wa­ter evap­o­rates, cool­ing it down in much the same way as sweat cools down hu­mans.

What could it be used for?

So far, Ken­goro can per­form around 100 dif­fer­ent types of sub­tle move­ment – around a quar­ter of what a hu­man is capable of, if you dis­count fa­cial mus­cles. Even so, the re­search has many pos­si­ble fu­ture ap­pli­ca­tions, in­clud­ing the de­sign of bet­ter crash dum­mies and more ef­fi­cient pros­thet­ics.
