This article announces a project to create a robotic system for servicing a fleet of agricultural drones. The system includes a ground station, a group of drones, and an external control panel, developed as a unified automated complex. The ground station is designed to transport drones in a special compartment and automatically deliver them from this compartment to the takeoff and landing platform located above the station. A payload module with a tank filled with spraying liquid and a charged battery is automatically attached to the drone. The equipped drone departs on its spraying mission, while another drone is brought to the platform from the compartment. Flights are conducted in fully automatic mode. Upon mission completion, the drone lands automatically on the platform, where a robotic manipulator removes the used module and replaces it with a loaded one. External system control by an operator includes inputting initial data for creating flight tasks for the drone fleet and monitoring the technological process, such as flight schedules, mission execution by drones, and technical condition checks of all subsystems. In case of conflicts, options for automatic and semi-automatic responses are provided. A systematic analysis of the automatic servicing pipeline for the drone fleet has been conducted, indicating significant improvements in efficiency for aerial agricultural treatment compared to traditional manual methods of servicing and managing drones.
