Provided herein are systems and methods for an unmanned aerial vehicle (UAV) to skid and roll along an environmental surface. A rollable UAV includes an airframe assembly, a propulsion system, and a logic device configured to communicate with the propulsion system. The airframe assembly includes a cylindrical rolling guard configured to allow the UAV to roll along an environmental surface in contact with the cylindrical rolling guard. The logic device is configured to determine a rolling orientation for the UAV corresponding to the environmental surface, maneuver the UAV to place the cylindrical rolling guard of the airframe assembly in contact with the environmental surface, and roll the airframe assembly of the UAV along the environmental surface at approximately the determined rolling orientation while the cylindrical rolling guard is in contact with the environmental surface.

Locomotion systems and methods for aerial vehicles

An airframe assembly for an unmanned aerial vehicle (UAV) is provided where the airframe assembly includes a top airframe assembly, a bottom airframe assembly, and a planar support frame disposed between the top and bottom airframe assemblies. The top and bottom airframe assemblies may form one or more rotor ducts disposed about one or more UAV propulsion motor mounts, respectively, where the rotor ducts are configured to protect rotating rotors disposed therein from physical damage caused by impact with environmental flight hazards. The airframe assembly may further include a heat sink thermally coupled to electronics of the UAV and disposed within the airframe assembly such that rotating blades in the rotor ducts cause air to be drawn from outside of inlet orifices of the top airframe assembly, through an airflow channel in which dissipation surfaces of the heat sink are disposed, and into a rotor duct via an airflow outlet.

Aerial vehicle architectures for improved thrust efficiency and internal cooling

A main body of an unmanned vehicle is provided. The main body comprises a propulsion-receiving module having a mount point for removably mounting a propulsion source, a payload-receiving module having a mount point for removably mounting a payload, and a damper interposed between the payload-receiving module and the propulsion-receiving module to inhibit transmission of vibrations from the propulsion-receiving module to the payload-receiving module when the payload-receiving module and the propulsion-receiving module are in mechanical communication.

Unmanned vehicle

Folding propeller system for safe packing and shipping, and easy deployment.

Folding propellers system

In an aspect, an apparatus includes a hovering unmanned aerial vehicle (HUAV). The HUAV includes an arm assembly configured to support a propeller in such a way that propeller drag of the propeller is decoupled from yaw torque requirements associated with the hovering unmanned aerial vehicle. In another aspect, an apparatus includes an HUAV that has an arm assembly that is field-foldable relative to the HUAV between a flight-ready state and a folded state. In another aspect, an apparatus includes an HUAV having an arm assembly that is keyed in such a way as to facilitate field-assembly relative to the HUAV.

Hovering unmanned aerial vehicle

An apparatus for presenting each of a first face and a second face of a document to a processing element to facilitate processing of the document thereby. The apparatus includes a first transport subassembly for moving the document along a first document path to present the first face of the document to the processing element. The apparatus also includes a gate adapted to permit movement of the document from the first document path to the second document path. In addition, the apparatus has a second transport subassembly for moving the document in the second document path in a reverse direction until the document engages a downstream side of the gate. The gate directs the document, upon engagement thereof with the downstream side, into the first document path with the second face of the document positioned for presentation to the processing element.

Apparatus and method for presenting both faces of a document for processing

An apparatus for obtaining data from a document at point of presentment. The document has a predetermined width, and the apparatus has a frame, a drive mechanism mounted on the frame, and sensors. The drive mechanism is adapted to move the document along a document path in the apparatus between a home position, at which the document is inserted into the apparatus, and an exit position, at which the document is removable from the apparatus. The drive mechanism includes a roller rotatable about a roller axis for engaging a contact portion of the document extending along the width thereof. The roller has a substantially smooth surface for supporting the contact portion. The sensors are for obtaining document data from the contact portion of the document.
