A robot torso structure

Abstract

The invention discloses a robot trunk structure. The robot trunk structure comprises a chest part, a waist part, a leg part and a base which are sequentially arranged from top to bottom; the waist part comprises a fixing frame assembly and a first steering engine arranged on the upper portion of the fixing frame assembly; the leg part comprises a support assembly and a second steering engine and a third steering engine which are arranged on the top and the bottom of the support plate assembly respectively, and the driven shaft end of the first steering engine, the driven shaft end of the second steering engine and the driven shaft end of the third steering engine are provided with a first connecting shaft mechanism, a second connecting shaft mechanism and a third connecting shaft mechanism respectively; the front side and the back side of the lower segment of the chest part are connected with a main output shaft of the first steering engine and the first connecting shaft mechanism respectively, the left side and the right side of the lower portion of the fixing frame assembly are connected with a main output shaft of the second steering engine and the second connecting shaft mechanism respectively, and the left side and the right side of the base are connected with a main output shaft of the third steering engine and the third connecting shaft mechanism respectively. The trunk structure has the more freedom degrees, can swing left and right and front and back, has the better environment adaption capacity and is simple in structure, reliable in performance and worthy of popularization in the industry.

Description

technical field [0001] The invention belongs to the technical field of robot devices, and in particular relates to a robot torso structure. Background technique [0002] Service robots are a young member of the robot family, which can be divided into professional field service robots and personal / home service robots. Service robots have a wide range of applications, mainly engaged in maintenance, repair, transportation, cleaning, security, rescue, guardianship, etc. Work. Data show that at present, at least 48 countries in the world are developing robots, of which 25 countries have set foot in the development of service robots. In Japan, North America and Europe, seven types of more than 40 service robots have entered experimental and semi-commercial applications so far. In recent years, the global service robot market has maintained a rapid growth rate. According to the data of the International Federation of Robotics, the sales volume of service robots in the global prof...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing research on service robots focuses on the intelligent control of the head platform, hand / leg joints, and feet / ground. For the trunk structure, it is basically composed of simple support members and shells, basically without degrees of freedom. In applications, especially for service robots, the applicability is not strong
