Fully Automatic Landing Site Selection by a UAV in an Unknown Environment

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Uncrewed aerial vehicles (UAVs) are widely deployed due to their low cost, autonomy, flexibility, and ability to operate in hard-to-reach areas. However, autonomous landing in unknown environments in the presence of hazards such as water or rough terrain

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Implications of high-spatial-resolution thermal infrared (Termoskan) data for Mars landing site selection [PDF]

, 1994
Thermal infrared observations of Mars from spacecraft provide physical information about the upper thermal skin depth of the surface, which is on the order of a few centimeters in depth and thus very significant for lander site selection.

Automatic Classification of Roof Shapes for Multicopter Emergency Landing Site Selection [PDF]

2018 Aviation Technology, Integration, and Operations Conference, 2018
Geographic information systems (GIS) now provide accurate maps of terrain, roads, waterways, and building footprints and heights. Aircraft, particularly small unmanned aircraft systems, can exploit additional information such as building roof structure to improve navigation accuracy and safety particularly in urban regions. This paper proposes a method
