Problems solved by technology
In general, one air cavity of a pneumatic soft robot needs to be controlled by one trachea. If the function of the soft robot becomes more complex, the number of air cavities will increase, which will also lead to an increase in the number of trachea. The increase in the number of trachea will inevitably lead to Difficulties in Locomotion for Soft Robots

The invention discloses a flexible dual-channel-control pressure release valve. The flexible dual-channel-control pressure release valve comprises a threaded outer shell, a three-hole outer shell andan elastic silica gel membrane, wherein the threaded outer shell at the upper part is in sealed butt-joint with the three-hole outer shell at the lower part, and the elastic silica gel membrane is clamped at the joint of the threaded outer shell and the three-hole outer shell; a hole-free knob is screwed on the inner side wall of the threaded outer shell, a spring is fixed to the center of the bottom of the hole-free knob, and the tail end of the spring is fixedly connected with a pressing block located at the bottom of the spring silica gel membrane; a communicating hole used for being connected with an upper control air pipe is formed in the portion, located between the hole-free knob and the edge of the bottom of the shell, of the threaded outer shell; a silica gel air pipe is arrangedin the three-hole outer shell in a penetrating manner, and an air hole used for being connected with the lower control air pipe is formed below a shell body of the three-hole outer shell; and a magnetboss corresponding to the pressing block in position is fixed on the bottom side of the inner part of the shell body of the three-hole shell. The pressure release valve is mainly applied to a pneumatic soft robot with rhythm and sequential movement.
Description
technical field [0001] The invention relates to the technical field of soft robots and fluid control, in particular to a flexible dual-channel controlled pressure relief valve body. Background technique [0002] Most of the robots used in traditional industries are robots with rigid structures. Although rigid robots have high rigidity, high working strength and fast execution efficiency, they are not suitable for grasping some brittle objects because the rigidity of any position cannot be adjusted. , such as eggs, biscuits, glass, etc. The development of modern science and technology is no longer satisfied with the design of robots with rigid structures. In order to further liberate human hands, robots can be used to solve more complex and dangerous tasks, so the exploration of soft robots continues to deepen and explore equipment. Constantly updated. In general, one air cavity of a pneumatic soft robot needs to be controlled by one trachea. If the function of the soft rob...
