Humanoid robots on the complexity of the man chosen to

What did not happen at these Web sites: robokolibri and cases and even robobelki … But with a robot that plays human movement (and reproducing in full), while the problem. It is very difficult Homo: both can run and climb, and even swim, and the number of degrees of freedom of the little people is enormous. However, researchers from the University of Tokyo (Japan) led by Yuto Nakanishi (Yuto Nakanishi) leave no hope.

Their creation is Kenshiro "descendant» Kojiro — muskoloskeletnogo drone, created in 2010. However, the prototype was like a man more external than internal: for example, the muscles he had less traffic and, accordingly, were not so complicated.

Not yet gymnast boar, but already able to movements purely human complexity. (Here and below, photos and illustrations, UT.)
Kenshiro, on the contrary, is very complex. Size and weight (158 cm, 50 kg), he "meets" 12-year-old Japanese boy. In this case, his "body" 160 "muscle": 50 feet, 76 in the body, the shoulders 12 and 22 in the neck. Today, it is the closest to the human anatomy for robotics creation. The complexity of movements even individual modules robot (to build) speaks for itself:

The question is, why bother to copy the human body? After all, similar in complexity robots with sizes comparable to our own, are much heavier than the standard mechminds. Say, one of the predecessors of Kenshiro, the robot body Kenzoh, weighed 45 kg. At full scale to 158 cm his weight would reach 100 kg. So much for that growth?

To avoid the "obesity", developers are guided not by the abstract engineering concepts, but from the "unit" of the person who observes its proportions both in size and in weight. The ultimate aim should be to get the robot to the "thrust" of course, equal to the human at the same rate of their human turning. Alas, this figure did not succumb to the Japanese: Kenshiro turns limbs in "joints" is just a speed of 70-100? in the second. However, the result is not so bad, most people over fifty feet safely rotate on a range of approximately the same rate. And sharing it with the human desire — by the way, the first time for humanoid robots.

But the degrees of freedom, even without hands, in this creation enough — already 64, including 13 for the neck, the same for each of the hands, and 7 for each leg. Even the "spine" has 11 degrees of freedom — though not as a healthy person, but for the present level of robotics just fine.

"Bones» Kenshiro get to do the weight close to human, but doing them out of aluminum. But to make their 3D-printer did not work: these robochasti most prone to failure.

Soon founder Kenshiro is going to take part in the famous contest Advanced Research Projects Agency of the Ministry of Defense (DARPA) called Robotics Challenge, which will provide another humanoid robot, which has, of course, the "military-applied value." Here it is, by the way:
