Interaction during delivery from aerial vehicle
First Claim
1. A system comprising:
- a retractable delivery system comprising;
(i) a tether coupled to an unmanned aerial vehicle (UAV) and configured to selectively secure a payload at a distal end of the tether, and (ii) a retraction system coupled to the tether and operable to raise the distal end of the tether towards the UAV from below, and to lower the distal end of the tether from the UAV towards a ground;
a bystander communication module, wherein the bystander communication module is configured to generate a pick-up cue for bystander perception; and
a control system configured to;
while the UAV hovers over a first location and the payload is at a ground location separate from the tether, use the retractable delivery system to lower the first end of the tether from the UAV towards a ground;
determine that the first end of the tether is at or near the ground;
in response to determining that the distal end of the tether is at or near the ground, cause the bystander communication module to generate a pick-up cue indicating readiness to pick up the payload;
after the payload is coupled to the distal end of the tether, initiating retraction of the tether such that the distal end ascends at a first ascent rate.

Abstract
An unmanned aerial vehicle (UAV) is disclosed that includes a retractable payload delivery system. The payload delivery system can lower a payload to the ground using an assembly that secures the payload during descent and releases the payload upon reaching the ground. The assembly can also include a bystander communication module for generating cues for bystander perception. While the assembly securing the payload is being lowered from the UAV, the bystander communication module can generate an avoidance cue indicating that bystanders should avoid interference with the assembly. The assembly also includes sensors that generate data used, at least in part, to determine when the descending assembly is at or near the ground, at which point the assembly releases the payload. The bystander communication module can then cease the avoidance cue and the UAV can retract the assembly.

13. A method comprising:
-
while an unmanned aerial vehicle (UAV) hovers over a first ground location, using a retractable delivery system to lower a distal end of a tether from the UAV towards ground, wherein the retractable delivery system comprises;
(i) the tether coupled to the UAV, (ii) a retraction system coupled to the tether and operable to raise a distal end of the tether with the payload coupled thereto towards the UAV, and to lower the distal end from the UAV towards a ground;determining that the distal end of the tether is at or near the ground; in response to determining that the distal end of the tether is at or near the ground, cause the bystander communication module to generate a pick-up cue indicating readiness to pick up the payload; and after the payload is coupled to the distal end of the tether, initiating retraction of the tether such that the distal end ascends at a first ascent rate. - View Dependent Claims (14, 15)

16. A system comprising:
-
a retractable delivery system comprising;
(i) a tether coupled to an unmanned aerial vehicle (UAV) and an assembly, and (ii) a retraction system coupled to the tether and operable to raise, towards the UAV, the assembly and a payload secured by the assembly, wherein the assembly comprises one or more electromechanical components configured to selectively secure the payload or release the payload;a bystander communication module, wherein the bystander communication module is configured to generate a pick-up cue for bystander perception; and a control system configured to; while the UAV hovers over a first location and the payload is at a ground location separate from the tether, use the retractable delivery system use the retraction system to lower the assembly from the UAV towards a ground; determine that the assembly is at or near the ground; in response to determining that the assembly is at or near the ground, cause the bystander communication module to generate a pick-up cue indicating readiness to pick up the payload; and after the payload is coupled to the assembly, initiating retraction of the tether such that the payload ascends at a first ascent rate.
