Abstract

The invention relates to a manipulator, in particular to a finger structure driven by a flexible hose to bend and a bionic hand. A fluid-driven one-way bending bionic finger comprises keels, an elastic supporting column and a flexible hose, wherein the keels are of hollow structures, the multiple keels are arranged, the multiple keels are sequentially arranged on the elastic supporting column in asleeve mode to form the bionic finger, the every two adjacent keels make contact through a supporting structure, the flexible hose is spirally attached to the bionic finger from bottom to top, one part of the flexible hose is attached to the keels, and the other part of the flexible hose is located between the every two adjacent keels, and after the flexible hose is expanded, the keels can be bent towards one sides of the supporting structures. The fluid-driven one-way bending bionic finger solves the problems that an existing manipulator finger is complex in structure, driven by electric power, low in flexibility, large in weight and high in cost.

Description

technical field [0001] The invention relates to a manipulator, in particular to a finger structure driven by a flexible hose and a bionic hand. Background technique [0002] The bionic hand is widely used in practical engineering, and grasps and releases the target object through the mutual cooperation of multiple fingers bent and straightened. However, the existing manipulators usually have the following problems: [0003] 1) The structure is complex, and the performance becomes more obvious as the number of bionic finger joints increases; [0004] 2) High cost and complicated control; [0005] 3) It is inconvenient to operate in special environments such as underwater to provide the main power with electricity, and the energy consumption is large; [0006] 4) The rigid structure is less flexible. Contents of the invention [0007] The invention proposes a fluid-driven one-way bending bionic finger to solve the problems of complex structure, electric drive and low fle...
