Abstract

We analyze the concept of multiple unmanned aerial vehicles (UAVs) on a shared tether (MUST), where the UAVs act as control nodes for the shape of the tether, enabling the system to maneuver around obstacles without tangling or colliding for increased flexibility compared with single-tethered UAVs. MUST use cases are gathered from stakeholders in the military, public safety, and commercial domains. We present a model for the tether shape to use in collision checking and a model for the interactions among tether weight, size, and power, which we exercise to determine the maximum tether segment sizes. We apply three probabilistic path-planning algorithms from the literature to MUSTs, using a novel local planner and constraint set. In simulation, we show that probabilistic planners are a feasible approach to path planning for MUSTs with curved tether segments. We also show the first manual piloting modality of MUSTs.
