The paper presents the development, design, and experimental verification of a system for autonomous delivery and installation of seismic sensors as a separate component of a nodal seismic network automated deployment complex. The system includes an unmanned aerial vehicle (UAV) with a hexacopter configuration, a capture device, and an automated landing subsystem, which ensures autonomous transportation, precise positioning, and installation of sensors weighing up to 5 kg. The UAV design included configuration selection, propeller-motor group calculation, material selection, and modeling. Laboratory tests of the system confirmed its compliance with the stated requirements: the capture device successfully captured sensors in 87% of cases, and the flight duration with a full payload reached 16 min 20 s. The system demonstrated stability at a crosswind of up to 10 m/s and readiness for further integration into the complex. The results obtained highlight the importance of the development for seismic exploration tasks and other areas requiring autonomous solutions.
