Abstract:
Unmanned aerial vehicles (“UAVs”) which fly to destinations (e.g., for delivering items) may land on transportation vehicles (e.g., delivery trucks, etc.) for temporary transport. An agreement with the owner of the transportation vehicles (e.g., a shipping carrier) may be made for obtaining consent and determining compensation for landings, and the associated transportation vehicles that are available for landings may be identified by markers on the roof or other identification techniques. The routes of the transportation vehicles may be known and utilized to determine locations where UAVs will land on and take off from the transportation vehicles, and in cases of emergencies (e.g., due to low batteries, mechanical issues, etc.) the UAVs may land on the transportation vehicles for later retrieval.
Abstract:
This disclosure is directed to varying a speed of one or more motors in an unmanned aerial vehicle (UAV) to reduce unwanted sound (i.e., noise) of the UAV. A UAV may include motors coupled with propellers to provide lift and propulsion to the UAV in various stages of flight, such as while ascending, descending, hovering, or transiting. The motors and propellers may generate noise, which may include a number of noise components such as tonal noise (e.g., a whining noise such as a whistle of a kettle at full boil) and broadband noise (e.g., a complex mixture of sounds of different frequencies, such as the sound of ocean surf). By varying the controls to the motors, such as by varying the speed or revolutions per minute (RPM) of a motor during operation by providing random or pseudo-random RPM variations, the UAV may generate a noise signature with reduced tonal noise.
Abstract:
Some examples include an inventory system having both mobile drive units remotely controllable to transport inventory items and holders within a warehouse and automated aerial vehicles remotely controllable to identify and remove amnesty items from the storage region. In some implementations, the automated aerial vehicles are equipped with imaging components to monitor the floor of the warehouse to identify and engagement mechanisms to secure and remove the amnesty items that may otherwise impede the movement of the mobile drive units.
Abstract:
A mobile base is provided that travels through delivery areas and utilizes associated transportation units (e.g., automated aerial vehicles, automated mobile vehicles, etc.) for delivering items from the mobile base to user specified delivery locations. The transportation units may be carried on the mobile base and may utilize navigation systems (e.g., utilizing GPS) to travel back and forth to the mobile base when making deliveries. Tracking data (e.g., GPS) may be utilized for status monitoring and notifications, as well as providing a map that may show and update the current locations of the transportation units and/or mobile base.
Abstract:
Described is an unmanned aerial vehicle (“UAV”) that includes a lifting propulsion mechanism that is circumferentially-driven and includes a propeller assembly and a propeller rim enclosure. The propeller assembly includes a plurality of propeller blades that extend radially and are coupled to an inner side of a substantially circular propeller rim that encompasses the propeller blades. Permanent magnets are coupled to an outer side of the propeller rim. The propeller rim and the magnets are positioned within a cavity of the propeller rim enclosure such that the propeller rim will rotate within the propeller rim enclosure. Also within the cavity of the propeller rim enclosure are electromagnets that are used to cause the propeller rim to rotate.
Abstract:
Described is an unmanned aerial vehicle (“UAV”) payload receiving apparatus that may be secured to a side of a structure, such as a human residence, and positioned such that a UAV can deliver a payload into the UAV payload receiving apparatus without the UAV having to land or navigate into an area that includes objects that could be harmed by the UAV and/or harm the UAV. The UAV payload receiving apparatus may include a plurality of securing members for securing the UAV payload receiving apparatus to the structure. A top frame is coupled to the securing members, positioned in a substantially horizontal direction when the UAV payload receiving apparatus is secured to a structure, and forms an opening of a size sufficient for a payload to pass through when the payload is released by a UAV positioned above the UAV payload receiving apparatus. The UAV payload receiving apparatus also includes a payload retainer, such as a net or bag, that is coupled to and extends in a downward direction from the top frame. The payload retainer receives and retains a payload that is placed in the UAV payload receiving apparatus.
Abstract:
A mobile base is provided that travels through delivery areas and utilizes associated transportation units (e.g., automated aerial vehicles) for delivering items from the mobile base to user specified delivery locations. The transportation units may be carried on the mobile base, or may be stationed in specific geographic areas, and may travel back and forth to the mobile base when making deliveries. The mobile base may include an automatic storage and retrieval system for automatically presenting items at an extraction point (e.g., on the roof of the mobile base), where items may be engaged by transportation units for delivery.
Abstract:
Unmanned aerial vehicles (“UAVs”) which fly to destinations (e.g., for delivering items) may land on transportation vehicles (e.g., delivery trucks, etc.) for temporary transport. An agreement with the owner of the transportation vehicles (e.g., a shipping carrier) may be made, and the associated transportation vehicles that are available for landings may be identified by markers on the roof or other identification techniques. Different types of communications may be provided as part of a landing process (e.g., a notification regarding a proposed landing may be sent including a request for a confirmation that the proposed landing is acceptable, etc.). The routes of the transportation vehicles may be known and utilized to determine locations where UAVs will land on and take off from the transportation vehicles.
