Head-eye coordinated movement device for humanoid robot

Abstract

The invention discloses a head-eye coordinated movement device for a humanoid robot. The head-eye coordinated movement device is composed of two eye movement mechanisms, a head-shaped shell and a neckmovement mechanism. The two eye movement mechanisms are installed on the positions of two eyes of the head-shaped shell, and the neck movement mechanism is installed below the head-shaped shell. According to the head-eye coordinated movement device, the structure is clear and compact, the size is reasonable, movement is coordinated, the strength of a rigid structure and the flexibility of a flexible structure are both achieved, and normal movement of the eyes and the head movement of head raising, head lowering, head shaking, head rotating and the like can be achieved.

Description

technical field [0001] The invention relates to the technical field of humanoid robots, in particular to a head-eye coordinated movement device for humanoid robots. Background technique [0002] A humanoid robot has a human appearance, can imitate the human body's motor function, perception system and social ability, and can inherit part of human experience. It belongs to the category of service robots. It simulates human beings in appearance and behavior design. It is a kind of robot that is easy to gain human favor, intimacy and emotional recognition. Compared with other robots, humanoid robots have greater adaptability and flexibility, and are more suitable for working with humans in the environment where humans live and work, or work instead of humans. It can not only replace human operations in complex environments such as radiation and dust, but also be widely used in many fields, such as medical care, education, entertainment, fire protection, etc. [0003] The huma...

AI Technical Summary

Problems solved by technology

[0004] At present, there are various head-eye coordination mechanisms of humanoid robots, and some research results have reached a relatively high level. However, due to the complex internal structure of the head and the high price, it is currently difficult to apply it to actual service robots.

However, all kinds of humanoid robots on the market have poor head movement flexibility, or only focus on solving a certain aspect of the problem

For example, the stability, rigidity, and accuracy of the neck structure driven by flexible cables are not enough; the orthogonal multi-axis neck structure is not flexible enough, and the movement space of the head-eye structure is easily constrained

In summary, there are often the following three problems: first, the structure is complex and expensive; second, the size is abnormal, which does not meet the requirements of humanoid appearance; third, the structure is flawed, the function is incomplete, and the application is very inconvenient.
