Abstract

The invention belongs to the field of soft mechanical arms, and provides a pneumatic soft clamping hand with a variable grabbing range and a using method of the pneumatic soft clamping hand. The pneumatic soft clamping hand comprises a finger supporting frame and soft fingers, wherein the positions of the soft fingers at the supporting frame extending end are adjusted by forming guide grooves in the supporting frame extending end of the finger supporting frame, and further the opening degree of the soft fingers is adjusted, so that the grabbing force is increased to adapt to different grabbing objects; large cavities and small cavities are provided with air inlets and are independently controlled by an air source, so that the bending degree of the soft fingers is increased, the clamping hand has higher stability in the object grabbing process, and grabbing is firmer; each soft finger is provided with a corrugated large cavity and the corrugated small cavity, and different air pressures are input into large air bags and small air bags of the cavities, so that objects are grabbed and released by the soft fingers; and the soft fingers are made of flexible materials, so that the degree of damage to an object can be reduced when the object is grabbed.

Description

technical field [0001] The invention relates to the field of soft manipulators, in particular to a pneumatic soft gripping hand with a variable grasping range and a use method thereof. Background technique [0002] Traditional rigid manipulators have been widely used in human social production and life. Rigid manipulators can perform tasks quickly, accurately and repeatedly in the grasping work of industrial sites, but the production process is relatively complicated, high cost, limited flexibility, man-machine The interaction is weak and the adaptability to the environment is poor. [0003] With the continuous advancement of science and technology, the quality requirements for manipulators are becoming more and more stringent. Rigid manipulators are difficult to meet the requirements in some areas, such as grasping fragile objects, objects with irregular surface shapes, and soft products. Therefore, the emergence of soft robots has become inevitable. With the development ...
