Deformable mechanical jellyfish based on cam-gear compound transmission

Abstract

The invention discloses a deformable mechanical jellyfish based on cam-gear compound transmission. A jellyfish head, a jellyfish body and a jellyfish tail are connected and sealed through waterproof glue; the jellyfish main body is composed of the jellyfish tail and a multi-connection-rod mechanical arm, and a remote-control switch is arranged in the jellyfish body; when a main control board sendsan instruction, a speed reducing motor rotates to drive a cam disc to rotate, the cam disc rotates to drive a cam rack to do feed motion, the cam rack can drive the multi-connection-rod mechanical arm to move in a quick-returning and slow-stretching mode, meanwhile the cam rack can drive a plurality of gears to rotate through the feed motion, the gears rotate to drive a sliding rack to do feed motion, a sliding rack can drive connection rods to do feed and rotation motion, and a locating structural part and a sliding head component are further driven to do vertical motion. By means of a cam-gear structure combined bionic transmission mechanism and by means of controlling motion of a plurality of motors, bionic motion that the jellyfish quickly returns and slowly stretches to drive the head to shrink can be achieved; thus, convenience is brought to underwater detection and scientific work, and the deformable mechanical jellyfish has a wide application prospect.

Description

technical field [0001] The invention relates to the field of underwater robots, in particular to a deformable mechanical jellyfish based on cam-gear compound transmission. Background technique [0002] At present, common unmanned underwater vehicles such as autonomous underwater vehicles (Autonomous Underwater Vehicle, AUV), Remotely Operated Vehicles (Remotely Operated Vehicle, ROV), etc., mostly use traditional propeller propellers. Propeller propulsion technology has irreplaceable advantages in practical applications, and both theoretical research and practical applications are relatively mature; but it also has its own shortcomings, such as large noise, large disturbance to the environment, poor movement flexibility and concealment, and the application occasions restricted. In order to improve the movement ability of underwater robots, scientific and technological personnel continue to study new propulsion methods, strive to obtain inspiration from colorful fish, imitat...

Propeller propulsion technology has irreplaceable advantages in practical applications, and both theoretical research and practical applications are relatively mature; but it also has its own shortcomings, such as large noise, large disturbance to the environment, poor movement flexibility and concealment, and the application occasions restricted

However, it does not truly simulate the jellyfish's rapid return and drainage movement process, it is just a jellyfish-like robot with a water spray mechanism
