Bionic scallop robot based on jet propulsion

Abstract

The invention discloses a bionic scallop robot based on jet propulsion. The bionic scallop robot comprises two casings, a casing connector, a motor, a spring, a flexible thin plate and corresponding circuit modules; the two outer casings are connected by the casing connector and pins and can be freely rotated around the pins; the motor is fixed to the casing connector; a rotating arm is arranged at the front end of the motor; bearings are arranged at two ends of the rotating arm; a smooth boss, a steering device, a spring fixing member and a flexible-thin-plate fixing plate are arranged in each casing; each smooth boss comprises a boss body and a boss cover and has a large internal space for holding the corresponding circuit module; each steering device comprises a driver and a blocking device; the center of each spring fixing member is provided with a through hole, and two ends of the spring can pass through the through holes to be fixed to the spring fixing members. The bionic scallop robot has the advantages that efficiency and continuity of the jet propulsion can be improved effectively, the swimming performance such as the steering ability of the jet propulsion can be remarkably boosted, and zero-turning-radius steering can be easily realized; the bionic scallop robot has low noise, small disturbance and high invisibility.

Description

technical field [0001] The invention belongs to the technical field of robots, and relates to an underwater bionic robot, in particular to a bionic scallop robot based on jet propulsion. Background technique [0002] Among the various technologies of ocean exploration and exploitation, underwater bionic robots are one of the most important components. They have very important application prospects in water quality detection, underwater resource exploration, submarine volcano monitoring, underwater search and rescue, and military fields. Underwater bionic robots are mainly divided into three categories: body caudal fin propulsion type, central fin-to-fin propulsion type and jet type. The traditional jet type cannot achieve very good motion effects due to poor motion continuity, low motion efficiency, and weak steering ability. The scallop is a very unique aquatic creature with a very special form of jet propulsion. Traditional forms of jet propulsion such as cephalopods or...

Problems solved by technology

Traditional forms of jet propulsion such as cephalopods or other shellfish absorb water from one end and spray water from the same end, thus limiting the continuity of motion
