Abstract

The invention discloses a pneumatic flexible composite bionic mechanical hand. The pneumatic flexible composite bionic mechanical hand is composed of bionic finger parts and a bionic palm part. Each bionic finger part comprises a base body, a first air cavity, a first air cavity channel, a non-extension layer, a second air cavity, a second air cavity channel and a ventilation plug. According to the technical scheme, pneumatic flexible composite bionic mechanical fingers take the index finger structure parameter of which the function ratio is the highest as a reference, and double-joint pneumatic actuators are adopted to replace human hand three-joint fingers so that the effect that the structure is simplified while effective grabbing is achieved can be realized.

Description

technical field [0001] The invention relates to the field of soft robots, in particular to a pneumatically driven soft and soft hybrid bionic manipulator. Background technique [0002] With the increasing requirements for the precision and wide applicability of robot grasping, the objects to be manipulated by robots are also shifting from regular, structured, and rigid objects to chaotic or unstructured areas. The rigid and low-degree-of-freedom end-effectors used in traditional robot manipulators usually have large inertia and high cost, limited types of actions that can be performed, low safety factor, poor environmental adaptability, low reliability, low transmission efficiency, and high noise , often encounter difficulties in unstructured and highly crowded environments, and can no longer meet the requirements of certain space and structure constraints, complex and changeable environments, and diversified structures of operating objects. [0003] The bionic soft robot c...
