Bionic quadruped robot with single-axis two-degree-of-freedom structure

Abstract

The bionic quadruped robot comprises a robot head structure, a robot belly structure, a robot tail structure and a neck steering structure, the robot head structure is connected with the robot belly structure through the neck steering structure, one end of the robot belly structure is connected with the robot tail structure, and the other end of the robot belly structure is connected with the robot tail structure. Leg structures are connected to four corners of the robot abdomen structure; the joint is simple and compact in structure, and flexible swinging of the joint and compression of the internal space of the robot are achieved; the neck part adopts a single-shaft two-degree-of-freedom structure, two steering engines are put down in a smaller space, the head shaking and nodding actions of the bionic cat are realized, the structure is novel, the movement is flexible, and the occupied space is small; and the tail part adopts a wire pulling mechanism, the reciprocating swing of each tail joint on one plane is realized by utilizing the rotation of a vertical coil, and the balance of the bionic cat during movement can be kept through the movement of the tail part structure.

Description

technical field [0001] The invention relates to the field of robots, in particular to a bionic quadruped robot with a single-axis two-degree-of-freedom structure. Background technique [0002] The quadruped bionic robot is a common product in the bionic robot, and the rotating joint is an important component of the robot. The flexibility and occupied space of robot joints will greatly affect the bionic performance and space utilization of the robot. Flexible and compact robot joints are the main determinants of the overall performance of the robot. In the current quadruped bionic mechanical products, the joints are too rigid and inflexible and occupy too much space, which is not conducive to the longitudinal development of the robot and the utilization of the internal space of the robot. Therefore, a bionic quadruped robot with a single axis and two degrees of freedom structure is provided. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provi...
