Wireless addressing starfish-like soft robot driven by vapor-liquid phase change

Abstract

The invention discloses a vapor-liquid phase change driven wireless addressing starfish-like soft robot, and belongs to the technical field of bionics. The soft robot solves the problems that an existing soft robot is poor in flexibility, large in size and few in adaptive working environment. The flexible execution part comprises a plurality of wrist feet and flexible deformation limiting layers correspondingly and fixedly connected to the bottoms of the wrist feet, the control part comprises a transmitting coil and a plurality of receiving coils, each wrist foot is communicated with the vapor-liquid phase change cavity through a fluid pipeline, each fluid pipeline is provided with a fluid valve, a heating film is electrically connected with one receiving coil, the fluid valves are correspondingly and electrically connected with the other receiving coils, wireless addressing is conducted through the transmitting coil to control the fluid valves corresponding to the receiving coils to be opened, and then wireless addressing is conducted through the transmitting coil to control the heating film to generate heat, so the low-boiling-point liquid in the vapor-liquid phase change cavityis boiled into vapor and enters the carpal tunnel through the fluid pipeline, and the carpal tunnel is deformed and bent.

Description

technical field [0001] The invention relates to a wireless addressing imitation starfish soft robot driven by vapor-liquid phase change, which belongs to the field of bionic technology. Background technique [0002] Due to its good compliant structure, flexible and continuous deformation characteristics, high safety and environmental adaptability, soft robots have great application potential in medical rehabilitation, emergency rescue, resource survey, pipeline inspection and military investigation. . Existing fluid-driven soft robotic actuation usually requires multiple gas input channels and cables, so that each actuator can be inflated and deflated according to a specific pre-programmed sequence. The robot is connected to the outside world through gas channels and cables, which seriously restricts the robot's activity space and the flexibility of the robot's movement. In addition, most of the existing wireless soft robots carry batteries and hardware control equipment, ...

AI Technical Summary

Problems solved by technology

The robot is connected to the outside world through gas channels and cables, which seriously restricts the robot's activity space and the flexibility of the robot's movement.

In addition, most of the existing wireless software robots carry batteries and hardware control equipment, and the working time, working environment, and size of the robot are limited, such as working in the human body.

Although some chemically driven robots do not have batteries and external air sources, they cannot independently control their movements and can only achieve repetitive actions.

In soft robots, battery-free, tether-free, multi-degree-of-freedom independent control of soft robot motion is challenging
