ABSTRACT Unmanned aerial‐aquatic vehicles (UAAVs) have gradually emerged as a robotics research hotspot in recent years due to their wide range of potential applications in both military and civilian domains. Although the structural design and related theoretical research of these prototypes have been validated in UAAVs, there are still many problems that need to be addressed, such as inflexible and unstable medium transition of the vehicles and the stability control during the transition process, etc. Therefore, there is an urgent need for further research on existing designs of UAAVs, power selections, water‐entry/exit strategies and optimization of key technologies. By summarizing the design and related technologies of existing UAAVs, including propulsion choices, transition methods, and motion control algorithms, this paper aims to provide references for the future research and development of UAAVs.
