Novel biomimetic side line sensor

Abstract

The invention provides a novel biomimetic side line sensor. An application target is positioned to be an underwater robot. The main function is to help the robot do fluid environment sensing, including the sensing on the fluid speed, the acceleration and the waving frequency. By extracting information obtained by the sensor through detection, the robot can independently perform operation posture regulation. The biomimetic principle of the sensor is based on the fish side line sensing organ; in the operation process of the underwater robot, the force is transmitted onto a stress rod through theimpact effect of the water flow in a direction vertical to the biomimetic cilium direction; then, the stress beam deformation is further caused; a detection element metal foil type strain gage on thestrain beam detects the deformation quantity of the strain beam; the deformation quantity is converted into voltage signals to be transmitted out; finally, the corresponding relationship between thefluid change and the voltage signal change can be obtained, so that the fluid state around the underwater robot can be judged through extracting the voltage feedback signals.

Description

technical field [0001] The invention relates to the technical field of underwater sensors, in particular to a novel bionic lateral line sensor. Background technique [0002] Natural light cannot penetrate below 1000 meters in the deep sea. In this dark environment, vision can no longer play a role. However, fish living in this environment can fly freely, hunt and avoid the pursuit of natural enemies. It relies on the lateral line organs of fish. The discovery of the fish lateral line system inspired scientists to sense the fluid environment by creating a bionic lateral line system. At present, there are very few research reports on the application of the lateral line sensing principle for underwater adaptive regulation on unmanned autonomous underwater vehicles. Contents of the invention [0003] The invention relates to a new type of bionic lateral line sensor, which has a compact structure and reasonable arrangement, adopts the bionic lateral line mechanism based on fi...
