Abstract

Stations for deployment, recharging and/or maintenance of a plurality of unmanned aerial vehicles (UAVs) are disclosed herein. Such deployment stations can be implemented in a container that includes a robotic arm and a conveyor system. The robotic arm can secure a UAV hovering outside the station, move the UAV inside the station, and transfer the UAV to the conveyor. The conveyor can couple to and move multiple UAVs. Further, charging systems may be integrated in such deployment stations to charge UAVs when coupled to and moving along the conveyer. Further, process pieces may be utilized to simplify mechanical and electrical interfacing between a UAV, the robotic arm, the conveyor, the charging system and/or other systems at the UAV station.
