Abstract
The design of propulsion system is a very critical task because it determines the performance of underwater robots, such as maneuverability and endurance and so on. Generally, it is a challenge to develop a propulsion system which can make tradeoff among multiple degree-of-freedom (DOF) motions, simple and compact structure and low power consumption. Thus, we are motivated to propose a collaborative propulsion system for the underwater robot and its unique reconfigurable structure makes vectorial propulsion possible.
Highlights
Nowadays, people pay more attention to exploring abundant marine resources while facing worldwide energy shortage issues
We propose a novel collaborative propulsion system for the underwater robot, which consists of a Coanda effect based primary propulsion system and a magnetic coupling based auxiliary propulsion system
3D model of the collaborative propulsion system was built in CATIA and it was imported into ANSYS WORKBENCH for meshing
Summary
People pay more attention to exploring abundant marine resources while facing worldwide energy shortage issues. With the rapid development of technology, underwater robots play significant roles in ocean resource exploitation. In some human inaccessible or hazardous areas, autonomous underwater vehicles (AUVs) are capable of sensing surroundings and navigating themselves to perform specific tasks, such as underwater structure inspection, marine resource exploration, marine environment monitoring [1,2,3,4,5]. These applications require AUVs with high maneuverability and reliable power supply. The propulsion system design is a key part for underwater robots development [6,7].
