Abstract: An electric-powered watercraft with at least one retractable hydrofoil and an advanced guidance and control system is described. The retractable aspect of the at least one hydrofoil allows for simpler dry-land and shallow-water transport and handling of the watercraft. The guidance and control system allows for improved maneuverability, better stability, greater motor efficiency and reduced power consumption.

Abstract: An unmanned vehicle (UV) is provided for transmitting data to a payload device connected to the UV. The UV comprises a processor configured to control operations of the UV, a first and a second communication interface for connecting to a payload device, a third communication interface for communicating with a remote station, and a non-transitory memory device storing instructions configured to cause the processor to to receive and transmit data. The processor is configured to receive one or more data packets through the third communication interface from the remote station, transmit the one or more data packets to the payload device through the first communication interface when the one or more data packets are designated for the first communication interface, and transmit the one or more data packets to the payload device through the second communication interface when the one or more data packets are designated for the second communication interface.

Abstract: 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.

Abstract: An unmanned aerial vehicle and process for automatically calibrating the unmanned aerial vehicle having at least one magnetic sensor is described. The calibration process involves receiving an internal or external control command to initiate a take-off process by the unmanned aerial vehicle. A hover mode maintains the unmanned aerial vehicle at hover position, and a calibration rotation sequence rotates the unmanned aerial vehicle. The calibration process further involves receiving measurement data from sensors of the unmanned aerial vehicle during the calibration rotation sequence and calculating calibration parameters using the measurement data. The calibration process may implement corrections using the calibration parameters.

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

Abstract: A system is provided comprising a control station for remotely controlling unmanned aerial vehicles (“UAV”). The control station is configured to display vehicle status data received from each UAV, including displaying a location of each UAV in a single interface. Through the single interface, the control station may receive a control command input associated with one of the UAVs. The control station may transmit the received control command, or a command derived therefrom, to the respective UAV. The single interface may provide for a user to view and control flight operation of each of the UAVs independently through the single interface.

Abstract: 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.
