Advancements in Drones with Improved Payload Management

An automated system for a drone to pick up payloads without human assistance. The system uses a ground-based apparatus with a funnel and channel. The drone lowers a retriever mechanism that slides down the funnel into the channel and grabs the payload. The drone can then lift the payload, disengaging it from the apparatus.

Method for unmanned aerial vehicles (drones) to precisely unload goods into an autonomous vehicle's storage box. The drone analyzes an image of the vehicle to recognize a marker inside the box. It adjusts its position based on the marker's location until it is within a threshold distance from the box center. Then, if the goods have a suitable handling attribute, the drone lowers them on a wire into the open box and releases the grip. If not, it releases the grip in mid-air above the box. The marker is normally hidden under the closed lid, but the drone can request the vehicle to open it via wireless communication to expose the marker.

A way to securely attach packages to drones for delivery and retrieval. The system uses a package coupling apparatus with a hanger and strap. The hanger attaches to the drone payload retriever and the strap wraps around the package. This securely connects the package to the drone so it can be lifted, transported and lowered using the retriever and a tether.

An attachment mechanism secures packages to drones for delivery. The mechanism has a support plate that attaches to the top of a package and an extended handle. The handle has an opening and bridge that can be grasped by a drone's payload retriever. This allows the drone to lift and transport the package while keeping the payload enclosed. The package attachment avoids the need for external dangling straps or hooks.

An unmanned aerial vehicle (UAV) system for delivering and retrieving payloads autonomously while providing user interaction and feedback capabilities to enhance safety and usability. The system uses a tethered payload coupling apparatus that automatically detaches from the payload after delivery. The tether is winched to lower and raise payloads while allowing user interaction via the tether. The winch motor monitors patterns indicative of user interaction and responds accordingly. The motor can counter, assist, or retract against forces applied to the tether.

A payload coupler for suspending and controlling a load from a lifting device like a drone. The coupler has an attached propulsion system that generates forces to keep the coupler in a stable position when suspended. This allows the coupler to hold position relative to the lifting device while the drone moves. The forces can be vertical and lateral components to oppose gravity and stabilize the coupler. It also has a payload attachment and release system for connecting loads.

A payload coupling apparatus for unmanned aerial vehicles (UAVs) that enables stable payload retrieval at high speeds. The apparatus has a housing with perforations in the upper, lower, and side portions. The housing also has a downward slot forming a hook/lip. The perforations stabilize the apparatus during high-speed UAV flight.

A drone delivery system that automatically decouples from payloads when they land to avoid getting tangled and damaged. The system involves a payload coupling apparatus with a slot to hold the payload handle during flight. When the drone lowers the payload, the coupling apparatus continues down until the payload handle is released from the slot. The apparatus design prevents re-engagement after release.

An unmanned aerial vehicle (UAV) delivery system that uses a decoupling capsule to automatically release payloads on the ground. The system involves a slot in the capsule that receives a payload handle during flight. When the UAV lowers the payload to the ground via a winch and tether, the capsule continues downward, decoupling from the handle. The capsule design prevents re-engagement during retrieval to avoid snagging. The decoupling is automatic and based on motion, not user input. The UAV can sense the decoupling event and retract the tether.

Detecting insecurely held payload on a robotic vehicle and taking corrective action. The payload security is monitored during transport and any payload that becomes loose or separated triggers corrective actions to prevent accidents or damage. The actions include adjusting payload securing mechanisms, changing navigation plans, activating additional sensors, transmitting alerts or requests for assistance, or even parking the vehicle.
