Development of a Fixed-Wing Drone System for Aerial Insect Sampling
(MDPI, 2022-08)
Most current insect research techniques are ground-based and provide scarce information about flying insects in the planetary boundary layer (PBL), which remains a poorly studied ecological niche. To address this gap, we ...

An aerodynamic extension for motion planning with dynamics awareness in aerial long-reach manipulators
(Hindawi Publishing Corporation, 2020)
This paper presents a novel method for motion planning of aerial long-reach manipulators that considers the aerodynamic effects generated by close surfaces in the trajectory generation process. The aerial manipulation ...

Aerodynamic reduced-order Volterra model of an ornithopter under high-amplitude flapping
(Elsevier, 2022-02)
The unsteady aerodynamics of flapping low-aspect-ratio ellipsoidal-wings in ornithopters is analyzed and modeled by the use of three dimensional Computational Fluid Dynamics (CFD) simulations. The range of interest is high ...

A 79.7g Manipulator Prototype for E-Flap Robot: A Plucking-Leaf Application
(IEEE, 2022-06-17)
The manipulation capabilities of flapping-wing flying robots (FWFRs) is a problem barely studied. This is a direct consequence of the load-carrying capacity limitation of the flapping-wing robots. Ornithopters will improve ...
