Autonomous Service Platform for Spraying UAVs: System for Mixing Solutions

Abstract

Maintenance of agricultural spraying drones (UAVs) currently requires manual dosing of highly concentrated and toxic products (with dilution ratios of 1:100 and higher), which is not always performed with sufficient accuracy. The developed multi-channel modular system for mixing working solutions is designed for the automated preparation of liquids and refueling of UAVs. The developed system ensures versatility due to the ability to prepare solutions in a wide range of required dilution ratios from 1:10 to 1:1000 and higher while maintaining high dosing accuracy. A fundamental distinction of the developed system is the inclusion of dosing modules of two different designs, each optimized for a specific range of dosing volumes and concentrate dilution ratios. The system fully automates the preparation and refueling process, eliminating the need for the operator to be constantly present in the hazardous area near operating UAVs and minimizing their exposure to highly concentrated toxic substances. The system is designed for use as part of mobile or stationary autonomous service platforms for servicing UAV fleets.
