Abstract

The invention provides a pneumatic flexible driver. The pneumatic flexible driver comprises a hollow shell, a spring and an air pump, the shell comprises a telescopic section, the telescopic section is of a telescopic spiral fold type structure, the spring is located in the telescopic section and abuts against the inner wall of the telescopic section, and the air pump is connected with the shell. The air pump is used for extracting air in the shell or inflating the shell, so that the telescopic section shrinks or extends in the axial direction. The invention further provides a net catching type pneumatic grabbing device.

Description

technical field [0001] The invention relates to the technical field of flexible robots, in particular to a pneumatic flexible driver and a net-type pneumatic grabbing device. Background technique [0002] Due to its good dexterity, flexibility and human-computer interaction, soft robots are increasingly used in many fields such as intelligent manufacturing and medical care. Flexible robots are all composed of flexible drives. Existing flexible drives include motor drive, gas-hydraulic drive, and functional material drive. Among them, the control performance of the motor-driven manipulator is better; the flexibility of the gas-hydraulic drive flexible manipulator is better, and Pneumatic air source is easy to install and light in weight. Pneumatic drive is the most widely used in light flexible manipulators; functional material drives are driven by shape memory alloys, ultrasonic waves, polymers and functional liquids, which require small and light manipulators. Occasions ha...
