Abstract: A condition of an unmanned aerial vehicle (UAV) is detected using one or more sensors of the UAV and signaled according to an alert definition associated with the condition. For example, an alert definition can indicate to signal the condition by using a motor of the UAV to produce an audible tone. A tonal signal having a frequency within an audible spectrum can be generated according to the alert definition. The tonal signal and a drive signal used for supplying current to the motor can be combined to produce a combined signal. The combined signal can then be transmitted to the motor to cause the motor to produce the audible tone. In some cases, an amplitude of the tonal signal can be modulated, such as where the amplitude of the combined signal exceeds a threshold associated with an operating margin of the UAV.

Abstract: The present teachings provide a non-transitory computer-readable storage medium, including a processor-executable routines that, when executed by a processor, facilitate a performance of operations. The operations include detecting a condition using one or more sensors of a vehicle, wherein the vehicle includes motors. The operations include signaling the condition by causing one of the motors of the vehicle to produce an audible tone. The operations include defining an operating margin for the one of the motors to produce the audible tone. The operations include changing an amount of operating current supplied to the one of the motors based on a maximum amount of current that can be supplied to the one of the motors based on the operating margin.

Abstract: This disclosure describes a method of controlling an unmanned aerial vehicle (UAV). The steps of controlling include acquiring images with an image capture device of an unmanned aerial vehicle (UAV). The steps include analyzing the images to determine navigation information of the UAV with a vision-based navigation system. The steps include tracking a position of the UAV with the vision-based navigation system. The steps include controlling rotors of the UAV to prevent deviations in movement from a desired flight path or position of the UAV. The steps include limiting travel or flight of the UAV to a physical region determined by the desired flight path.

Abstract: This disclosure describes systems and methods for a multipoint cable cam (MPCC) of an aerial vehicle. A method includes operations of receiving user input associated with a predetermined path and correlating the received user input with stored global positioning satellite (GPS) data to generate one or more virtual waypoints along the predetermined path. The method includes processing the one or more virtual waypoints to generate a spline-based flight path. The method may include storing the spline-based flight path and transmitting the spline-based flight path to the aerial vehicle.

Abstract: The position of a UAV within a three-dimensional space is changed based on a change in position of a controller of the UAV. First and second sensor data are produced using sensors of the controller to maintain stable altitude output for the UAV. The first sensor data indicates a geolocation of the controller, and the second sensor data indicates a barometric pressure of an environment in which the controller is located. The first and second sensor data are post-processed using a complementary filter based on respective altitude measurements of the first and second sensor data to determine an altitude of the controller. A position of the controller is determined within a three-dimensional space based on the altitude. Data indicative of the position of the controller within the three-dimensional space is then transmitted to the UAV to cause a change in a position of the UAV within the three-dimensional space.
