The purpose of this work is to create methods in which multi-agent systems can coordinate actions and complete them at the same time. We utilized A* with constraints defined by a dynamic model of each agent. The model for each agent is updated during each time step and the resulting control is determined. This results in a translational path that each of the agents is physically capable of completing in synchrony. The resulting path is given to the agents as a sequence of waypoints. Periodic updates of the path are calculated, utilizing real-world position and velocity information, as the agents complete the task to account for external disturbances. Our methodology is tested in a dynamic simulation environment as well as on real-world lighter-than-air robotic agents. <\/jats:p>","DOI":"10.1142\/s2301385020500181","type":"journal-article","created":{"date-parts":[[2020,3,10]],"date-time":"2020-03-10T15:47:40Z","timestamp":1583855260000},"page":"253-260","source":"Crossref","is-referenced-by-count":25,"title":["Swarm and Multi-agent Time-based A* Path Planning for Lighter-Than-Air Systems"],"prefix":"10.1142","volume":"08","author":[{"given":"Jason","family":"Gibson","sequence":"first","affiliation":[{"name":"Distributed Autonomous Systems Group, U.S. Naval Research Laboratory, 4555 Overlook Ave SW, Washington, DC 20375, USA"}]},{"given":"Tristan","family":"Schuler","sequence":"additional","affiliation":[{"name":"Distributed Autonomous Systems Group, U.S. Naval Research Laboratory, 4555 Overlook Ave SW, Washington, DC 20375, USA"}]},{"given":"Loy","family":"McGuire","sequence":"additional","affiliation":[{"name":"Distributed Autonomous Systems Group, U.S. Naval Research Laboratory, 4555 Overlook Ave SW, Washington, DC 20375, USA"}]},{"given":"Daniel M.","family":"Lofaro","sequence":"additional","affiliation":[{"name":"Distributed Autonomous Systems Group, U.S. Naval Research Laboratory, 4555 Overlook Ave SW, Washington, DC 20375, USA"}]},{"given":"Donald","family":"Sofge","sequence":"additional","affiliation":[{"name":"Distributed Autonomous Systems Group, U.S. Naval Research Laboratory, 4555 Overlook Ave SW, Washington, DC 20375, USA"}]}],"member":"219","published-online":{"date-parts":[[2020,7,20]]},"reference":[{"key":"S2301385020500181BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/ICARCV.2018.8581376"},{"key":"S2301385020500181BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/CCTA.2017.8062564"},{"key":"S2301385020500181BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/ICRA.2017.7989369"},{"key":"S2301385020500181BIB004","doi-asserted-by":"publisher","DOI":"10.1007\/BF01386390"},{"key":"S2301385020500181BIB005","doi-asserted-by":"publisher","DOI":"10.1109\/TSSC.1968.300136"},{"key":"S2301385020500181BIB007","doi-asserted-by":"publisher","DOI":"10.1080\/13658810801949850"},{"key":"S2301385020500181BIB008","doi-asserted-by":"publisher","DOI":"10.25046\/aj040107"},{"key":"S2301385020500181BIB010","first-page":"228","volume-title":"2018 15th IEEE Int.
