Micro Untethered Swimming Robot

Abstract

The invention discloses a miniature cable-free swimming robot which comprises head part, a fuselage and a tail fin, wherein the head part is arranged at one end of the fuselage, and the other end of the fuselage is fixedly connected with one end of the tail fin. The miniature cable-free swimming robot is characterized in that the head part and the fuselage are in hollow structures inside, the fuselage is internally provided with a piezoelectric ceramic stack, a micrometric displacement amplifying structure and lateral fins made of giant magnetostrictive thin film hyperbolic plates, all of which are symmetrically distributed, wherein the head part is internally provided with a radio frequency transceiver, and the lower part of the fuselage is internally provided with a drive power. With the adoption of the technical scheme, the miniature cable-free swimming robot makes main movement realizes highest work by depending on the external magnetic field, and realizes steering motion by depending on the drive device with low power consumption, and is simple in structure and long in time of endurance, thus having a very good practical value.

Description

【Technical Field】 [0001] The invention relates to the technical field of micro-robots, in particular to the technical field of micro-cableless swimming robots. 【Background technique】 [0002] Micro-swimming robots are currently a research hotspot in the world. The main potential applications such as blood vessel robots for clearing blood clots have made considerable progress. Micro-swimming robots used in blood vessels are usually not due to the special working environment. It is a cableless robot with a cable connected to the external controller or power supply; the energy supply mode of the cableless robot is divided into the built-in power supply and the power supply. [0003] The Chinese patent (application number: 03129612.2) proposes a tadpole-like spiral micro-robot. The components include a head, a body, a tail, a micro motor, a tail swing mechanism, a head rotation mechanism, a head sink and float controller, and a micro The camera system and the radio frequency transceiv...

Problems solved by technology

[0005] The purpose of this invention is to solve the problem that the existing vascular robot needs to rely on the built-in power supply to supply power to the drive system, and the robot’s battery life is short. The robot can make the micro-swimming robot rely on the external magnetic field to achieve the main movement with the greatest work, and rely on the low-power drive device to realize the steering movement. It has a simple structure and a long battery life, which has good practical value.
