Future applications will necessitate more complex articulated systems that will be tasked to operate with increased safety, efficiency, and capacity. In this article, we present a novel motion planning framework for enabling, for the first time, safe autonomous navigation and active perception in high-dimensional articulated AUVs, employed with multiple arbitrary-configured sensors, in complex dynamic environments that are prone to uncertainties, disturbances, and currents. Inspired by previous work, we expand on a locally optimal and empirically safe pipeline designed for holonomic AUVs and enable it to handle articulated AUVs with potentially non-trivial dynamics that are unknown to the planner. We test the proposed methodologies with challenging simulated cases using an underwater snake robot (USR) with realistic dynamics and a generic underwater vehicle-manipulator system (UVMS) comprising of a holonomic base employed with a manipulator. Our results showcase the effectiveness of the proposed technique in producing efficient and safe real-time solutions, while discussing current limitations, computational bottlenecks, and potential solutions.<\/jats:p>","DOI":"10.3389\/frobt.2026.1789488","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T04:33:39Z","timestamp":1789101219000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Autonomous navigation and active perception with complex articulated AUVs"],"prefix":"10.3389","volume":"13","author":[{"given":"Marios","family":"Xanthidis","sequence":"first","affiliation":[{"name":"SINTEF Ocean","place":["Trondheim, Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kostas","family":"Alexis","sequence":"additional","affiliation":[{"name":"Department of Engineering Cybernetics, NTNU","place":["Trondheim, Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eleni","family":"Kelasidi","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Industrial Engineering, NTNU","place":["Trondheim, Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"333","DOI":"10.1007\/bf00133571","article-title":"Active vision","volume":"1","author":"Aloimonos","year":"1988","journal-title":"Int.
