Embodiment Construction

[0024] This embodiment is a fuselage of a bionic quadruped robot. Includes front fuselage, rear fuselage and connecting spine. The front fuselage includes a box body 5, two front fuselage shock absorbers 4, two front leg connecting blocks 2, two pairs of upper swing arms 3 and two pairs of lower swing arms 1. The rear fuselage comprises a tripod 11, a front fuselage shock absorber 12 and a rear leg connection block 13. The connecting spine includes the first vertebral connecting rod 6, 10 torsion springs 8, 4 vertebral connecting rods 9, the end vertebral connecting rod 10 and 5 transition pieces 14, and is composed of the first vertebral connecting rod 6, 4 vertebral connecting rods 9 It is hinged with the end vertebral connecting rod 10 in turn.

[0025] The two front leg connecting blocks 2 of the front fuselage are located on both sides of the rectangular box body 5, and are connected to the box body 5 through two pairs of upper swing arms 3 and two pairs of lower swing ...

Abstract

The invention discloses a machine body of a bionic quadruped robot. The machine body comprises a front machine body, a back machine body and a connecting backbone, wherein the connecting backbone is formed by hinging a first backbone connecting rod, a multi-section backbone connecting rod, a transition piece and a tail end backbone connecting rod in sequence; two front leg connecting blocks of the front machine body are connected with a box body through two pairs of upper swing arms and two pairs of lower swing arms; the two ends of two front machine body dampers are connected with the box body and the front leg connecting blocks respectively; the two ends of a back machine body three-way support are fixedly connected with two back legs of the robot respectively; and the connecting backbone passes through a space between the front machine body and the back machine body. The invention provides a machine body of the bionic quadruped robot, which has waist degree of freedom, high leg and waist connecting flexibility and waist flexibility, according to a felid simulation body structure. By adopting the machine body, the leg and machine body connecting flexibility of the robot is enhanced, posture adjustment of the quadruped robot in the walking, running and jumping processes is facilitated, the waist flexibility of the robot is enhanced, and the waist and leg coordination of the quadruped robot is enhanced.

Description

technical field [0001] The invention relates to the field of robots, in particular to a fuselage structure of a bionic quadruped robot. Background technique [0002] Quadruped robots are more stable than bipedal and three-legged robots, simpler in structure than hexapod robots, flexible in motion, and have a strong carrying capacity. They have good application prospects in emergency rescue and disaster relief, military fields, and life and entertainment. The mechanical structure of the robot limits the development of the quadruped robot to a great extent. In terms of the mechanical structure of the robot, the lack of flexibility of the fuselage limits the functions of the robot such as walking, running, jumping and rolling, and affects the sensitivity, stability and adaptability of the robot. At present, foreign representative bionic quadruped robots include the TITAN series developed by Japan's Shigeo Hirose Laboratory, the Tekken series of pet dog-shaped robots developed ...
