Testing of untethered subscale models, often referred to as subscale flight testing, has
traditionally had a relatively minor, yet relevant use in aeronautical research and …

A robust landing control algorithm is proposed for a quadcopter, as well as for a landing
platform to land on an inclined or problematic surface. To use the quadcopter for outdoor …

In this study, a bioinspired multi-finger robot system (MFRS) is designed based on the
characteristics of eagle claws. The MFRS is attached to a rotary-wing unmanned aerial …

Small offshore platforms rock and heave under the impact of waves. The adaptive landing
gear should reduce the impact force between the landing legs and the platform while …

Vertical take-off and landing unmanned aerial vehicles (VTOL UAV) are widely used in
various fields because of their stable flight, easy operation, and low requirements for take-off …

Due to the highly efficient multi-domain mobility, land-air amphibious vehicles are of great
value in providing emergency assistance, such as disaster relief and reconnaissance. In this …

In this paper, the concept of adaptive landing and aerial manipulation mechanism (ALAM) is
proposed. The mechanism can be installed on a rotary-wing unmanned aerial vehicle …

Rotorcraft Unmanned Aerial Vehicles (UAVs) often need to take off and land under complex
working conditions. The rugged terrains may cause the UAV to tilt during takeoff and landing …

Unmanned helicopters equipped with adaptive landing gear will dramatically extend their
application especially in dealing with challenging terrains. This study presents a novel cable …

The ecological impacts of meltwater produced by icebergs and sea ice in the waters around
Greenland are poorly understood, due in part to limited observations. Current field sampling …
