A five-degree-of-freedom combined action mechanism

By designing a five-degree-of-freedom combined motion mechanism and using a cross joint and multiple geared motor drive mechanisms, the motion simulation of the human head and neck in five degrees of freedom was realized, improving the simulation accuracy. In particular, it can simulate the movement of the head swaying left and right while the neck remains stationary in Xinjiang dance.

AI Technical Summary

Technical Problem

Existing robot head and neck mechanisms can only perform pitching and swaying movements, failing to effectively simulate the multi-degree-of-freedom movements of the human head and neck, resulting in low simulation fidelity.

Method used

Design a five-degree-of-freedom combined motion mechanism, including a cruciate joint, a neck drive mechanism, a head swing mechanism, a head pitch mechanism, and a head twisting mechanism, to simulate the five degrees of freedom of human head and neck through the coordinated drive of these mechanisms.

Benefits of technology

It achieves motion simulation of five degrees of freedom of the human head and neck, improving the simulation accuracy, especially the ability to simulate the movement of the head swaying left and right while the neck remains still in Xinjiang dance.

Abstract

This invention belongs to the field of robotics, and specifically relates to a five-degree-of-freedom (DOF) combined motion mechanism. The technical solution is as follows: a five-degree-of-freedom combined motion mechanism includes a cross joint connected to a body base. A neck drive mechanism is connected to each side of the output end of the cross joint. The other end of each neck drive mechanism is mounted on the body base. The two neck drive mechanisms are used to drive neck swinging or pitching movements. A head swinging mechanism is also connected to the output end of the cross joint. The output end of the head swinging mechanism is connected to a head pitching mechanism, and the output end of the head pitching mechanism is connected to a head twisting mechanism. This invention provides a five-degree-of-freedom combined motion mechanism.
