Real‐Time Motion Generation for Robot Manipulators in Complex Dynamic Environments
Advanced Intelligent Systems, EarlyView.A motion generation method for robot manipulators in complex dynamic environments is presented. The method integrates global motion planning with local obstacle avoidance, ensuring continuous movement toward dynamically measured target poses. An online distance calculation algorithm is developed, and a collision‐free motion generator is proposed that ...

Predicting Visibility of Aircraft
PLoS ONE, 2009 Visual detection of aircraft by human observers is an important element of aviation safety. To assess and ensure safety, it would be useful to be able to be able to predict the visibility, to a human observer, of an aircraft of specified size, shape, distance, and coloration. Examples include assuring safe separation among aircraft and between aircraft

Treecreeper Drone: Adaptive Mechanism for Passive Tree Trunk Perching
Advanced Intelligent Systems, EarlyView.Taking inspiration from treecreepers, a passively triggered aerial robot that can reliably perch on vertical tree trunks is presented. The friction‐based approach combines a microspine array with a tail‐like support, and then validates via dynamic analyses and flight experiments, ensuring stable performance across trunk diameters and bark textures ...

CFD predictions of near-field pressure signatures of a low-boom aircraft [PDF]
, 1992 A three dimensional Euler marching code has been utilized to predict near-field pressure signatures of an aircraft with low boom characteristics. Computations were extended to approximately six body lengths aft of the aircraft in order to obtain pressure
