Modular machine dolphin flipper driving mechanism

Abstract

The invention relates to a modular mechanical dolphin flipper drive mechanism, which is characterized by a main motor module, an auxiliary motor module and a support; the main motor module includes a main motor shell; a top cover and a bottom cover are respectively sealed and connected above and below the main motor shell; the top cover is connected with a press cover; a main motor is arranged in the main motor shell; the output of the main motor goes through the top cover and the press cover by sealing devices; the auxiliary motor module includes an upper and a lower shells as well as the top cover and the press cover which are sealed and connected; an auxiliary motor is fixed in the lower shell by two support blocks; both sides of the lower shell are respectively provided a rotating shaft hole; the output of the auxiliary motor is connected to the flipper of the mechanical dolphin; one end of the support is support is connected the rotating shaft hole on one side of the auxiliary motor module, and the output of the main motor goes through the support and is connected to the rotating shaft hole on the other side of the auxiliary motor module. The mechanical dolphin flipper drive mechanism of the invention can be taken as not only an auxiliary advancing mechanism for the mechanical dolphin, but also taken as an independent underwater advancing mechanism.

Description

technical field [0001] The invention relates to a robot dolphin, in particular to a modular robot dolphin flipper drive mechanism. Background technique [0002] At present, with the rapid development of robot technology, the deepening of research on the swimming mechanism of fish and the expansion of the demand for the development and utilization of marine resources, the research of underwater bionic robots has received more and more attention. Some schools at home and abroad , scientific research institutions have achieved good results in the research of robotic fish. Compared with fish swimming, dolphins are agile and swim fast, and have better performance in terms of swimming efficiency, drag reduction mechanism, maneuverability, sonar detection, etc. Robot dolphins are used in underwater detection and underwater detection. , bionic research and other fields have broader application prospects. The research on robotic dolphins is an interdisciplinary research that includ...

AI Technical Summary

Problems solved by technology

The research on robotic dolphins is an interdisciplinary research that includes biology, hydrodynamics, materials science, automatic control, robotics, etc. At present, people's research on dolphin swimming models and their special drag reduction mechanisms is not deep enough. Practical difficulties have not been well resolved, and the research work on robot dolphins still needs further exploration and practice
