Robotics, Automaton and Automation Design Honeycomb Modular Multifunctional Drone by Mingxi Li Honeycomb is a modular unmanned aerial vehicle designed to perform several tasks. The frame has a hexagonal shape, inspired by a bee honeycomb, and can be expanded by adding more units. Functional modules for fire protection, public announcement, seeding, ultraviolet sterilization, spraying and delivery are held in the middle of the frame by strong magnets. A larger number of modules increases the carrying capacity. A built-in Bluetooth connection allows the position to be monitored. The drone measures 815 mm long, 815 mm wide and 363 mm high.
