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.
