Abstract: An example method includes identifying a degraded visual environment corresponding to a phase of a route followed by the vehicle. The method includes determining, based on the phase of the route, a first segment of a trajectory of the vehicle along which to search for a location with an improved navigation environment. The method includes causing the vehicle to follow the first segment until: (i) identifying the improved navigation environment, or (ii) reaching an end of the first segment without identifying the improved navigation environment. The method includes determining a second segment of the trajectory based on whether the improved navigation environment has been identified. The method includes causing the vehicle to follow the second segment.

Abstract: A method and corresponding apparatus and computer-readable storage medium are provided for causing one or more robots to execute a mission. The method includes identifying the mission including a nominal sequence of selected tasks that are executable to cause the one or more robots to execute maneuvers to achieve a mission objective. The method includes determining a task graph in which the mission is modeled. The task graph is expressed as a directed graph and includes selected task nodes representing the selected tasks that are connected by edges representing transitions between the selected tasks. The method also includes causing the one or more robots to execute the mission using the task graph and a task library of tasks including a selected task executable to cause the one or more robots to execute a maneuver.

Abstract: An apparatus is provided that includes a string of power sources and step-down circuitry. The power sources are connected in series to provide a first voltage rail at a first voltage, and the string of power sources is divided into power-source segments. The step-down circuitry electrically is configured to provide a second voltage rail at a second, lesser voltage. The step-down circuitry includes control circuitry configured to monitor states of charge of the power-source segments, and control selection of one of the power-source segments to deliver an output from which the second voltage rail is provided, based on the states of charge. One or more first electronic components are electrically coupled to the first voltage rail, and designed to operate at the first voltage. And one or more second electronic components are electrically coupled to the second voltage rail, and designed to operate at the second voltage.

Abstract: A method is provided for horizon detection. The method includes acquiring an image that depicts a view of an environment, and defining a line pattern of lines that divide the image into respective pairs of image segments. The line pattern is formed of lines that are parallel, or intersecting at a common point of intersection. The method includes searching the lines of the line pattern to identify one of the lines as an estimated true horizon in the image that divides the image into a respective pair of image segments at a boundary of greatest difference in average brightness between the image segments from among the respective pairs of image segments. The method includes determining true horizon in the image from the estimated true horizon. The method may also include an evaluation of the estimated true horizon or the true horizon as to verify one or more expected characteristics.

Abstract: A method is provided for supporting an aircraft to execute a mission in which the aircraft maneuvers in an airspace system. The method includes detecting a lost-link event in which a datalink between the aircraft and a control station is interrupted or lost, and responsive to which the aircraft is preconfigured to execute a procedure. The method also includes conveying an intent of the aircraft to execute the procedure over a radio channel assigned for voice communication in the airspace system. In this regard, conveying the intent includes composing a message that indicates the intent of the aircraft to execute the procedure. The message is applied to a text-to-speech engine to convert the message to a corresponding verbal message in which the intent of the aircraft is conveyed. The corresponding verbal message is then sent over the radio channel assigned for voice communication in the airspace system.

Abstract: An aircraft and a control system for the aircraft includes a tilt-wing defining an inlet configured to receive air and an outlet in fluid communication with the inlet such that the outlet is configured to expel the air. The control system includes a high-lift device coupled to at least one of a leading edge, and a trailing edge of the tilt-wing. The high-lift device is movable relative to the tilt-wing. The control system includes a compressor in fluid communication with the inlet and the outlet. The compressor is configured to increase pressure of the air that is expelled out of the outlet. The outlet directs the pressurized air toward at least one of the high-lift device and a center section of the tilt-wing to maintain attachment of airflow across the tilt-wing. A method of operating the control system of the aircraft occurs to maintain attachment of airflow across the tilt-wing.

Abstract: A method for controlling an aerial vehicle including a compliant arm mechanism is disclosed. A propulsion system of the aerial vehicle is controlled to fly the aerial vehicle to an area proximate to a surface. One or more of the propulsion system and the compliant arm mechanism are controlled such that the compliant arm mechanism contacts the surface. The compliant arm mechanism is configured to extend laterally beyond a perimeter of the propulsion system. One or more sensor signals indicating contact of the compliant arm mechanism against the surface are received via a sensor. A force at which the aerial vehicle presses against the surface is determined based on the one or more sensor signals.
