Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

open access: yesWildlife Biology, Volume 2026, Issue 5, September 2026.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Non-linear model predictive control of a tilt-rotor quadcopter for control allocation and path following

open access: yes2024 International Conference on Global Aeronautical Engineering and Satellite Technology (GAST)
The tilt-rotor quadcopter is an optimized structure of the standard quadcopter, which has actuating motors that can tilt about the quadcopter arm. A tilt-rotor quadcopter with more control inputs could theoretically bring stronger anti-disturbance and ...
