Abstract

The invention discloses a flow control low-noise soft valve driven by electric conjugate liquid. Two fluid outlets of a valve body are respectively communicated with a fluid inlet through an upper flow channel and a lower flow channel, an electric conjugate liquid cavity is arranged between the upper flow channel and the lower flow channel, electric conjugate liquid is stored in the electric conjugate liquid cavity, a flexible cathode and upper and lower flexible anodes are arranged in the electric conjugate liquid cavity, and the electric conjugate liquid cavity is connected with the upper flow channel and the lower flow channel. At the joint of the electric conjugate liquid cavity and the upper flow channel, an upper flexible valve is hermetically mounted at a port of the electric conjugate liquid cavity, and an upper groove is formed in the side wall of the upper flow channel. At the joint of the electric conjugate liquid cavity and the lower flow channel, a lower flexible valve is hermetically mounted at a port of the electric conjugate liquid cavity, and a lower groove is formed in the side wall of the lower flow channel. According to the flow control soft valve, electric conjugate liquid static pressure is actively controlled through voltage so as to control throttling and on-off of a loop, the response speed is high, and the flow control soft valve is suitable for controlling a driving fluid loop in a soft robot.

Description

technical field [0001] The invention relates to a fluid valve structure in the field of soft robots, in particular to a fluid control low-noise soft valve driven by an electric conjugate fluid. Background technique [0002] Soft robots have the advantages of strong adaptability and intrinsic safety, and have great application prospects in unstructured environment operations, complex and fragile object grasping, and human-computer interaction. Among them, fluid-driven soft robots have become the most active and promising research direction in this field because of their strong driving force, good controllability, and easy integration. The development of fluid drive and control methods has gone through three stages: In the first stage, drive and control are realized through rigid components such as a large number of external gas sources, pumps, and solenoid valves. The second stage gets rid of the external pipeline through the built-in rigid drive and control elements, but th...
