Effective ocean observation requires hybrid aerial-underwater vehicles (HAUVs) to operate efficiently across both air and water. However, such cross-domain missions often lead to significant hydro-aerodynamic conflicts and endurance limitations caused by structural redundancy. This letter proposes N
Hybrid aerial underwater vehicles (HAUVs) are developing rapidly with the urgent need for joint air-sea observation missions. This paper proposes a novel HAUV that combines a folding wing mechanism and an underwater thrust system with a centralized tail in an inverted triangle configuration. In addi…
Hybrid aerial underwater vehicles (HAUVs) provide unique capabilities for aerial and underwater observation and sampling, with a variety of configurations already developed. However, challenges in maneuverability, payload integration, and practicality persist, while their specific applications remai
Hybrid aerial underwater vehicles (HAUVs) exhibit significant potential due to their ability to operate seamlessly in the air and water domains. However, balancing rapid maneuverability in both media and achieving stability during the cross-domain phase remains a significant challenge. Inspired by t
Hybrid aerial underwater vehicles (HAUVs) hold great promise but face challenges like air-water integration and high underwater resistance. This paper presents Nezha-Morphing, a bio-inspired HAUV that emulates seabirds’ adaptive wing extension and retraction mechanisms for efficient movement in both
Hybrid aerial-underwater vehicles (HAUVs) are attracting significant interest for their unique capability to operate across both air and water. However, achieving a lightweight design coupled with efficient cross-domain performance remains a formidable challenge. This paper introduces Nezha-T, a nov

The hybrid aerial underwater vehicles (HAUVs) have promising applications due to their capability to operate in both air and water domains. It is a challenge to balance the rapid maneuverability in both media and the stability at the cross-domain phase. In this letter, Nezha-B, a bone-shaped HAUV pr
The fusion of hyperspectral images (HSIs) and LiDAR data can improve land cover classification performance. However, existing fusion methods do not well consider the large discrepancies between two modalities (e.g., brightness, structure, and the possible misalignment), leading to limited improvemen…
This letter proposes a novel conceptual multimodal underwater vehicle, named “Swift”, which is capable of dexterous attitude transition for multiple operation modes. Aside from being competent to adjust pitch and roll angles in the range of −90 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/
The air-sea interface is vital in studying heat and energy exchange between the sea and air. The field observation technology of the air-sea interface is an effective way to explore the nature of the air-sea interface. This paper presents an observation system called DANDELION for the air-sea interf…
This letter introduces a small hybrid aerial underwater vehicle (HAUV), which we named Nezha-F, that can fly in the air, perform vertical profiling underwater, and vertically take off and land from both the water surface and ground. A foldable and self-deployable arm mechanism linked to and driven b
Underwater thermocline, common in the lakes and ocean, plays a vital role in meteorological forecasting in the ocean and lakes dynamics research. This letter proposes a method for rapid and multipoint observation of thermocline variations with time and space using an airdropped micro-profiler array,…
The distinct design concepts of the vehicles operating in air and water is one of the tremendous challenges that constrain the development of the hybrid aerial underwater vehicle (HAUV). This incompatibility consequently results in the enlarging volume and weight of the existing prototypes, as well
A new solution to improving the poor endurance of the existing hybrid aerial underwater vehicle (HAUV) is proposed in this paper. The proposed multimodal hybrid aerial underwater vehicle (MHAUV) merges the design concept of the fixed-wing unmanned aerial vehicle (UAV), the multirotor, and the underw…
