Apparatus and method for retrieving unmanned aerial vehicles
Abstract:
A system and method for recovering unmanned aerial vehicles (UAVs) uses the fact that many small UAVs can hover in a vertical or near-vertical attitude. An exemplary system includes two or more rollers rotatable about respective axes of rotation, a mechanism to capture a UAV, and a support to which the rollers are mounted in such a way as to place the axes of rotation in parallel in a common plane. When the plane is in a vertical orientation, the capture mechanism is enabled to capture a UAV positioned adjacent the rollers. By hovering the UAV in the vertical position there is no forward velocity or momentum, and hence the craft can more easily be captured and the motor can be shut down without damaging the UAV. Misalignment during recovery is mitigated by cushioning in the rollers and the ability of the capture mechanism to compensate for imperfect alignment.
