Abstract: Focusing on low-altitude logistics and delivery scenarios using unmanned aerial vehicles (UAVs), this paper analyzes key technologies and research hotspots in the field through a keyword co-occurrence network map. According to the core components of UAV logistics systems, the study systematically reviews the domestic and international research issues such as motion and environment perception, flight control, route planning, UAV-truck cooperative optimization, profit allocation in cooperative operations, transportation safety and privacy security, and sustainable development of industry. Furthermore, the evolution process and application prospects of related control technologies and optimization methods are interpreted in detail, while the future research interests are concluded. The motivation of this review is to shed light on the trends in low-altitude UAV logistics and provide some insight for researchers.
