MINION: Modular and Independent Navigational Intelligent Orientable Nozzle-Thruster

The MINION concept, standing for Modular Independent Navigational Intelligent Orientable Nozzle-Thruster, encapsulates a modular propulsion unit designed for Unmanned Marine Vehicles (UMVs) with power, communication, computing power, sensors (GNSS, IMU), and directional thrust within a compact, watertight module. In other words the MINION concept posits that a modular directional thruster can work as a simple robotic vehicle, being equipped with all the sub-systems required to do it. Sets of MINION units can be suitably connected through mechanical frames and/or hulls to constitute different shape UMVs. The propulsion system is designed for UMV applications requiring modularity, redundancy, and independence, enhancing portability, design flexibility, and cable elimination. MINION operates using a mixed-flow or centrifugal pump, achieving precise 360° thrust control through a steerable nozzle, thereby optimizing maneuverability in marine environments. When integrated into an Autonomous Surface Vehicle (ASV), MINION functions as a propulsion and steering unit, computing element, navigation sensor package, and energy source, offering protection during bottom collisions. Moreover, the MINION architecture is designed to facilitate automated adherence to FAIR (Findable, Accessible, Interoperable, Reusable) data principles. This includes the promotion of standardized variable naming conventions, thereby enhancing the interoperability and reusability of data generated by marine robotic systems. © 2024, Institute of Marine Engineering Science & Technology.
