This is referred to as the urban air mobility (UAM) problem, and the UAM problem has emerged as a leading challenge for these drones in recent years. Agents must be capable of real-time dynamic obstacle avoidance, planning motion in accordance with their own constraints, and detecting system failures or potential adversarial attacks. They must also be prepared to react to the behavior of other agents in the environment expressing a variety of motion planning strategies, which can range from cooperative motion planning, independent motion planning, and even planning motion around potential adversaries. These requirements may not only demand improved motion planning strategies, but may also necessitate quick development of new autonomous systems to employ these strategies. In this thesis, we consider numerous challenges that face the development of UAM and propose a urban air motion planning framework for a number of cooperating \u201cplayer agents\u201d in the environment. We formulate a model-free method of learning the optimal control for the kinodynamic motion problem, and an algorithm to predict the behavior of independent or adversarial agents in the environment through a cognitive hierarchy approach. Additionally, we use repeated observations of numerous agents to mitigate any potential noise in agent observations. This thesis also considers the challenges of modeling the effects of constraints present on a UAV system, and proposes an efficient method to learn a binary \u201cgo\/no-go\u201d classifier by selecting informative training points via a soft actor\/critic (SAC) framework. We also use this same framework to augment target system inputs to ensure safe control online, as well as monitor the system to detect any potential hardware faults or adversarial attack. Both our motion planning framework and our efficient binary classification algorithm are demonstrated to be effective with numerous examples and simulations.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003EProf. Kyriakos Vamvoudakis \u2013 School of Aerospace Engineering (advisor)\u003C\/li\u003E\u003Cli\u003EProf. Samuel Coogan \u2013 School of Aerospace Engineering\u003C\/li\u003E\u003Cli\u003EProf. Christos Athanasiou \u2013 School of Aerospace Engineering\u003C\/li\u003E\u003Cli\u003EDr. Timothy Walsh \u2013 Sandia National Laboratories\u003C\/li\u003E\u003C\/ul\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EA Safe and Robust Multi-Agent Motion Planning Framework for Urban Air Mobility\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"A Safe and Robust Multi-Agent Motion Planning Framework for Urban Air Mobility"}],"uid":"27707","created_gmt":"2025-07-07 17:27:01","changed_gmt":"2025-07-07 17:27:28","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-07-15T10:00:00-04:00","event_time_end":"2025-07-15T12:00:00-04:00","event_time_end_last":"2025-07-15T12:00:00-04:00","gmt_time_start":"2025-07-15 14:00:00","gmt_time_end":"2025-07-15 16:00:00","gmt_time_end_last":"2025-07-15 16:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Montgomery Knight Building 317","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
