Height 158 ​​cm Weight 50 kg, moving movie of humanoid "Tendon Shiro" reproducing human skeleton and muscle

It is very difficult to imitate human muscles and skeletons, but the University of Tokyo's Information Systems Engineering Laboratory combines a motor and a pulley to "Human imitation musculoskeletal humanoid Tendon ShiroHe said he is developing a humanoid that acts like a human being saying "It's human." You can watch the movie as if it were moving smoothly as if it were alive.

The movement of the shoulder part is still a bit awkward, but feeling like a human. This Tendon Shiro is the predecessor of 2007 developmentKojiroWith the development of 2010TendonIt is a model following the tendon that more muscle parts and motors have been improved.


As the arms are attached, you can see how the shoulder part moves.


The part of the arm also moves, each joint is running and seems to be able to do complicated movements, it seems as if it is alive.



Legs will move, not just the arms.


Compared with Kojiro, it is capable of 5 times power output, so that it can also lift the leg like this is characteristic of Tendon Shiro.


This street is also in the opposite direction.


Tendon Shiro's legs can also move complicatedly so that the muscles will move and move.



The movement of the upper part including the spinal column etc. is also smooth. The skeleton is made of aluminum. Also, the spine has multiple joints as well as the human body, and the ribs and pelvis are reproduced. Tendon Shiro reflects most of the major muscles of human beings, with 50 legs on the leg, 76 on the trunk, 12 on the shoulder, 22 on the neck, and a total of 160 muscles resembling muscles are used.


It moves not only right and left, but also up and down and body turning without losing the balance.


I am still a bit awkward, but I can walk.


The part of the base of the leg also works and is opening and closing a lot. It is said that Tendon Shiro imitates an average Japanese man of 12 years old with a height of 158 cm and a weight of 50 kg.



Part of this knee was the movement which was very smooth among them. It also performs bending and stretching exercises, and even with fast movements it does not destroy the balance at all.


In the tendon of the previous generation, there was 45 kg only in the upper body part, and it was said that the weight was over 100 kg in total. It is too heavy as a small robot, so it seems that the result of designing to realize the same weight distribution ratio as human being became 58 kg tendons. It is designed to imitate human beings as well as weight of muscle torque and joint movement speed.


It may be close to developing a humanoid which is completely indistinguishable from a human like a terminator.
