Soft robotic bionic fingers

Abstract

The invention discloses a bionic finger of a flexible robot. The bionic finger comprises a housing and an air bag, wherein the housing comprises a fingertip housing, at least one middle connecting housing, a root housing and elastic joint sleeves. The fingertip housing is connected with the middle connecting housing through the elastic joint sleeve, the middle connecting housing is connected with the root housing through the elastic joint sleeve to form an integral cavity, each elastic joint sleeve comprises an axial long side and an axial short side, and the connecting positions of the fingertip housing, the middle connecting housing, the root housing and the elastic joint sleeves are matched in shape. The air bag comprises an air bag body and an air channel, wherein the air bag body is arranged into the cavity from the bottom of the housing, and the air channel is located at the bottom of the air bag body and is communicated with the outside. The bionic finger of the flexible robot achieves bending of the finger joints through a simple structure, and uses the single air bag as a driver so as to achieve the purpose that the bionic finger is low in control difficulty and capable of grabbing an article through the simple structure and a simple material.

Description

technical field [0001] The invention relates to a robot bionic finger, in particular to a flexible robot bionic finger. Background technique [0002] Robot technology is developing rapidly. At present, most humanoid manipulators are based on the mechanical structure to realize the bending of the finger joints. The fingers of the manipulator are composed of multiple joints connected in series, and the mechanical structure is driven by micro motors, pushing cylinders, and wire rope traction to realize the contraction of the fingers. , to achieve the purpose of precise control, but the structure is relatively complex, the control process is cumbersome, the application of the function of only grabbing items is less economical, and the cost is high, the mechanical structure is complex, easy to damage, and the control is difficult to meet the flexible control requirements. [0003] Therefore, there is a need for a robot with low control difficulty and simple structure and material...
