Abstract: In an example, a method of generating flight paths for navigating an aircraft is provided. The method includes hovering the aircraft at a predetermined hover point. The predetermined hover point corresponds to a first takeoff waypoint of a first trajectory of the aircraft. The method includes scanning at least a portion of a first flight path of the first trajectory. The method includes determining that an obstacle obstructs the first flight path of the first trajectory. The first flight path begins at the first takeoff waypoint. The method includes determining a second takeoff waypoint. Determining the second takeoff waypoint includes assigning the first flight path to begin at the second takeoff waypoint. The method includes changing the first flight path of the first trajectory in accordance with the second takeoff waypoint, thereby forming a second flight path of a second trajectory. The method includes causing the aircraft to follow the second flight path of the second trajectory from the second takeoff waypoint.

Abstract: Methods and apparatus are provided for allocating tasks to be performed by one or more autonomous vehicles to achieve a mission objective. Generally, a task allocation system identifies a final task associated with a given mission objective, identifies predecessor tasks necessary to complete the final task, generates one or more candidate tasks sequences to accomplish the mission objective, generates a task allocation tree based on the candidate task sequences, and searches the task allocation tree to find a task allocation plan that meets a predetermined selection criteria (e.g., lowest cost). Based on the task allocation plan, the task allocation system determines a task execution plan and generates control data for controlling one or more autonomous vehicles to complete the task execution plan.

Abstract: The present disclosure is directed to systems and methods for trajectory and route planning including obstacle detection and avoidance for an aerial vehicle. For example, an aerial vehicle's flight control system may include a trajectory planner that may use short segments calculated using an iterative Dubins path to find a first path between a start point and an end point that does not avoid obstacles. Then the trajectory planner may use a rapidly exploring random tree algorithm that uses points along the first path as seed points to find a trajectory or route between the start point and end point that avoids known or detected obstacles.

Abstract: A workpiece manipulation system to provide high-precision manipulation of a workpiece by an aircraft. The workpiece manipulation system comprises a lifting mechanism to couple with the aircraft, an end-effector, and a processor. The lifting mechanism includes one or more joint actuators to extend or retract the lifting mechanism relative to the aircraft. The end-effector includes an end-effector actuator to control an operation of the end-effector to manipulate the workpiece. The processor is communicatively coupled with the aircraft processor and configured to control operation of the end-effector actuator and the one or more joint actuators. In operation, the processor provides feedback to the aircraft.

Abstract: A method, apparatus, and system for processing images. A featureless surface is detected during at least a portion of a flight of an aircraft. A pattern is displayed in a fixed location on the featureless surface while the featureless surface is in a field of view of a camera system carried by the aircraft during at least the portion of the flight of the aircraft. Images of the featureless surface with the pattern in the fixed location using the camera system are generated during at least the portion of the flight of the aircraft.

Abstract: Provided herein are systems to allow an operator to sense, for example, distance of a component from a component connector. The systems include a transmitter associated with the component connector, and a feedback device operable to contact the operator. The feedback device comprises a receiver operable to receive signals transmitted by the transmitter, and an actuator operable to provide haptic feedback to the operator in which, for example, strength, manner, or strength and manner of actuation of the actuator is determined by strength of the signals received by the receiver. Typically, the systems further allow the operator to engage the component to the component connector. Other aspects of the present disclosure provide various methods of allowing an operator to sense, for example, distance of a component from a component connector and to related computer readable media.

Abstract: Propulsors, aircraft including the propulsors, and methods of directing a fluid stream in a propulsor. The propulsors include a housing defining a partially enclosed volume that extends from an inlet to both a first thrust outlet and a second thrust outlet. The propulsors also include a fan assembly including a plurality of blades and a blade pitch control mechanism that is configured to selectively vary a respective pitch angle of each blade in the plurality of blades. The fan assembly is configured to provide a motive force for fluid flow into the partially enclosed volume via the inlet. The propulsors further include an outlet flow control assembly configured to direct the fluid flow to preferentially exit the partially enclosed volume via a selected one of the first thrust outlet and the second thrust outlet. The aircraft include the propulsors. The methods include methods of operating the propulsors.

Abstract: An actuation system to manipulate an interface in an aircraft having an actuation controller, a vision system, a robotic arm, and a housing. Each of the vision system and the robotic arm assembly may be operatively coupled to the actuation controller. The vision system may be configured to optically image a display device of the preexisting interface, while the robotic arm assembly may be configured to engage a user-actuable device of the preexisting interface. The housing can be configured to affix to a surface adjacent the preexisting interface, where each of the vision system and the robotic arm assembly are coupled to the housing. In operation, the actuation controller may be configured to instruct the robotic arm assembly based at least in part on data from the vision system.

Abstract: An autonomous aerial vehicle includes a flight controller and a mission manager in communication with the flight controller. The flight controller is configured to navigate the autonomous aerial vehicle. The mission manager is configured to receive mission data. The mission data identifies both a landing zone and a designated touchdown zone located within the landing zone. The mission manager is further configured to provide flight control data to the flight controller. The flight control data causes the flight controller to navigate the autonomous aerial vehicle to a predetermined distance from the landing zone. The mission manager is further configured to determine, subsequent to the autonomous aerial vehicle reaching the predetermined distance, whether landing at the designated touchdown zone is feasible. The mission manager is further configured, in response to determining that landing at the designated touchdown zone is not feasible, to identify an alternate touchdown zone located within the landing zone for landing the autonomous aerial vehicle.
