Bendable robot trunk mechanism

Abstract

The invention discloses a bendable robot trunk mechanism. The bendable robot trunk mechanism comprises a trunk skeleton. The trunk skeleton comprises an upper-limb supporting skeleton, a knee-waist supporting skeleton and a lower-limb supporting skeleton, and the upper-limb supporting skeleton, the knee-waist supporting skeleton and the lower-limb supporting skeleton are sequentially arranged from top to bottom, wherein a waist joint is rotationally connected between the upper-limb supporting skeleton and the knee-waist supporting skeleton, and a knee joint is rotationally connected between the knee-waist supporting skeleton and the lower-limb supporting skeleton. The trunk mechanism comprises the upper-limb supporting skeleton, the knee-waist supporting skeleton and the lower-limb supporting skeleton, rotating is achieved through waist joint connection and knee joint connection, and the trunk structure can form a subhuman waist bending structure and a subhuman knee bending structure; the trunk mechanism is different from most existing columnar robot trunks, and can be applied to trunk design of a home service robot, the robot has the subhuman waist-and-knee bending action, and on this basis, related development of future functions of the robot can be greatly enriched, and the bendable robot trunk mechanism has broad applications.

Description

technical field [0001] The invention relates to a robot, in particular to a bendable robot torso mechanism. Background technique [0002] Existing household robots have a relatively simple structure. Most of their torsos are columnar structures, which mainly support and fix the head or arms. Since there is no waist or knee structure similar to humans, they cannot bend, The function of leaning forward or backward, so it is impossible to achieve complex movements that require bending down like humans. Although the industrial robot has the effect of bending the trunk, its structural design is complicated and the cost is high, so it cannot be directly transplanted into the design of the robot for home service. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings in the prior art that the torsos of household robots are mostly columnar and do not have curved structures and functions, and provide a bendable robot...
