Abstract: An unmanned aerial vehicle (UAV) including a winch system, wherein the winch system includes a winch line having a first end that is secured to the payload, and wherein the winch system is controllable to vary the rate of descent of the payload, an inertial measurement unit positioned on the payload or on the first end of the winch line, wherein the inertial measurement unit is configured to measure oscillations of the payload, and a control system configured to (a) receive data from the IMU, (b) determine oscillations of the payload based on the data received from the IMU, and (c) operate the winch system to vary the deployment rate of the winch line so to damp oscillations of the payload.

Abstract: Embodiments described herein may relate to methods and systems for supplying auxiliary power to an unmanned aerial vehicle (UAV) with different flight modes. In particular, the system may determine that a UAV is operating in a first flight mode. Responsively, the system may cause the UAV to draw power from a first power source at a first power level while operating in the first flight mode. Subsequently, the system may determine that the UAV switched from operating in the first flight mode to operating in a second flight mode. Responsively, the system may cause the UAV, while operating in the second flight mode, to continue drawing power from the first power source at the first power level and draw power from a second power source at a second power level, where the UAV consumes power at a higher rate during the second flight mode than during the first flight mode.
