Multi-connecting-rod robot head and neck control mechanism

Abstract

The invention discloses a multi-connecting-rod robot head and neck control mechanism. The mechanism comprises a base fixed with a body of a robot, a head support plate for fixing a head of the robot, a neck positioned between the head support plate and the base, and a neck control mechanism for controlling the neck to act; the lower end of the neck is hinged with the base through an universal hinge; and the neck control mechanism comprises at least two multi-connecting-rod mechanisms connected with the neck, and at least two motors I for correspondingly controlling the multi-connecting-rod mechanisms to act one to one. The mechanism is simple in structure, can flexibly and really simulate the head and neck actions of children, and enables the robot to be accepted by the aged more easily.

Description

technical field [0001] The invention relates to the field of robots, in particular to a multi-link robot head and neck control mechanism. Background technique [0002] The current head and neck mechanism of humanoid robot has complex and cumbersome structure, poor movement flexibility and low movement precision, especially the eyelid movement mechanism is not flexible enough; the transmission process is too cumbersome, the movement pair is unreasonable, the movement friction resistance of the mechanism is large, the noise is large, and the mechanism is stuck Phenomenon occur from time to time; poor structure hierarchy, poor installability and maintainability of the overall structure; the overall appearance and even the local size, as well as the range and speed of movement of each organ are quite different from the human head and neck, and the overall mechanism movement Coordination is not high. For example, in the three patent applications with application numbers 20141010...

[0002] The current head and neck mechanism of humanoid robot has complex and cumbersome structure, poor movement flexibility and low movement precision, especially the eyelid movement mechanism is not flexible enough; the transmission process is too cumbersome, the movement pair is unreasonable, the movement friction resistance of the mechanism is large, the noise is large, and the mechanism is stuck Phenomenon occur from time to time; poor structure hierarchy, poor installability and maintainability of the overall structure; the overall appearance and even the local size, as well as the range and speed of movement of each organ are quite different from the human head and neck, and the overall mechanism movement poor coordination

For example, in the three patent applications with application numbers 201410106710.2, 201502990283.9, and 201320291262.9, the robot neck mechanism has only three degrees of freedom, which cannot flexibly simulate the cuteness of children, and there are many non-standard parts, making it difficult to process and manufacture.
