A method, apparatus, and system for supplying power during the takeoff and landing of an Urban Air Mobility (UAM) aircraft is disclosed herein. A power supplying method is performed by a power supply system comprising a drone and a hub. The power supplying method includes: determining whether power is required for an Urban Air Mobility (UAM) aircraft to land on the hub using battery information of the UAM aircraft when the UAM aircraft is determined to be in a landing mode; moving the drone from the hub to the UAM aircraft using location information of the UAM aircraft when it is determined that power is additionally required for the UAM aircraft to land on the hub; docking the drone to the UAM aircraft to couple with; and supplying power required for the UAM aircraft to land on the hub to the UAM aircraft by the drone.

One method for finishing a surface includes utilizing a hovering surface finisher with a plurality of attachments and finishers coupled thereto. The surface finisher images a grid on an unfinished surface via a camera and a GPS tracks the location of the surface relative to the surface finisher. A user may program specified parameters, including height and angle above the surface, and speed and time at which the surface finisher flies across the grid to finish the surface. The system operating this process may include a connector that attaches the finisher to the surface finisher and sensors for determining the locational parameters. Utilizing the precise locational information from the sensors, the surface finisher may create various textures on the surface that increase the surface's longevity and safety by reducing slip and fall injuries.

Buoyancy modules filled with gases lighter than ambient air are described that are used to lift hoses and other lines off the surface of the ground. These buoyancy modules can support any line above the ground, the line delivering a fluid or energy from a source to a target.

The present invention provides systems and methods for placing anti-electrocution protective covers on an electric-pole's insulator bushings.

An unmanned delivery robot capable of being wirelessly charged during delivery, the unmanned delivery robot includes a wireless power reception module, a processor, and a storage medium recording one or more programs configured to be executable by the processor. The processor includes instructions for controlling a communication module to receive a delivery instruction including a delivery route to a destination, controlling a driving module to autonomously travel to the destination according to the delivery route included in the delivery instruction, and controlling the communication module to transmit battery information and location information in real time. The wireless power reception module charges the battery module by wirelessly receiving power from an unmanned charging drone autonomously flying to a current location of the unmanned delivery robot according to a charge instruction including the location information.
