Collision avoidance protocols such as COLREGS are written primarily for human operators resulting in a rule set that is open to some interpretation, difficult to quantify, and challenging to evaluate. Increasing use of autonomous control of vehicles emphasizes the need to more uniformly establish entry and exit criteria for collision avoidance rules, adopt a means to quantitatively evaluate performance,...
Closest Point of Approach (CPA) calculations are fundamental calculations for determining the utility and safety of a candidate maneuver of a marine vessel with respect to another vessel, i.e., contact. In certain kinds of path planning, a set of CPA calculations is made for thousands of candidate maneuvers, perhaps several times per second. Furthermore, with multiple contacts, multiple sets need...
This paper demonstrates the process of adapting publicly available repositories for the MOOS-IvP middleware to efficiently create and solve problems for collaborative marine autonomy. The problem introduced in this paper addresses a collaborative approach for autonomous environmental anomaly detection, bounding, and containment. An environmental anomaly may be an oil spill, radioactive contamination,...
Recently developed algorithms quantify and subsequently evaluate COLREGS performance in collision avoidance scenarios based on vessel track data. Combining these evaluation algorithms with proposed categories of COLREGS rules allows for testing of collision avoidance performance in accordance with protocol requirements. This paper proposes a “road test” framework for autonomous marine vehicles prior...
This document describes the MOOS‐IvP autonomy software for unmanned marine vehicles and its use in large‐scale ocean sensing systems. MOOS‐IvP is composed of two open‐source software projects funded by the Office of Naval Research. MOOS provides a core autonomy middleware capability, and the MOOS project additionally provides a set of ubiquitous infrastructure utilities. The IvP Helm is the primary...
