Abstract

The invention discloses an integral lightweight frame of a large-axisbase high-dynamic quadruped robot and its processing technology, including a head, a torso, and a tail; the head includes a head bar frame and a limb connection structure; the head bar The component frame includes the left bearing seat fixing rod group, the right bearing seat fixing rod group, the side swing plate fixing rod, the side swing plate lower fixing rod; the left bearing seat fixing rod group includes the left front bearing seat fixing rod, the left rear bearing Seat fixing rod; the right bearing seat fixing rod group includes the right front bearing seat fixing rod and the right rear bearing seat fixing rod; the limb connection structure includes bearing seats and leg and foot mounting rods; the integral lightweight frame is composed of several hollow rods; The wall thickness of the left bearing seat fixed rod group and the right bearing seat fixed rod group is greater than the wall thickness of the remaining rods; all the rods are fixedly connected with the L-shaped corner seat by welding process. The invention effectively solves the contradiction between the large wheelbase size span between the main shafts of each leg group of the integral lightweight frame and the requirement for high positioning accuracy.

Description

technical field [0001] The invention belongs to the technical field of robot body frames, and more specifically relates to an integral lightweight frame of a large-axisbase high-dynamic quadruped robot and a processing technology thereof. Background technique [0002] Footed robots have always been a research hotspot in the field of robotics because of their potential flexible locomotion and terrain adaptability. Since the birth of Boston Dynamics' Big Dog robot, prototypes of high-performance quadruped robots with different specifications have been continuously introduced. Although the dynamic motion capability of quadruped robots continues to improve, there are still many technical difficulties in the development of large-scale heavy-duty quadruped robots. [0003] The robot fuselage is the main structure that connects and positions the leg-foot limb mechanism. The overall frame structure with welding technology is used as the fuselage scheme, which is one of the methods...
