When the task calls for a aerial system that can hover in place, the often-chosen approach is to employ a tethered drone. A tethered drone, generally a multirotor, gets its power and communications signals via a flexible wire or cable. Where battery powered multirotor drones can exhaust their batteries in 20 minutes or so, tethered […]
