AI summary

Systems and methods using an Unmanned Aerial Vehicle (UAV) to perform physical functions on a cell tower at a cell site include flying the UAV at or near the cell site, wherein the UAV comprises one or more manipulable members; moving the one or more manipulable members when proximate to a location at the cell tower where the physical functions are performed to effectuate the physical functions; and utilizing one or more counterbalancing techniques during the moving ensuring a weight distribution of the UAV remains substantially the same.
