The creators of robots are forced to produce prototypes for each individual case. As a rule, these attempts do not reach commercial production of practicable robotic systems, and they are limited to experimental models.
The manufacturers of humanoid robots need a complete, inexpensive and simple humanoid structure to serve as a basis for the creation of humanoid robots.
The proposed design can meet the needs of robot makers, and to become a suitable solution for many experimental and practical cases.
