Abstract:
1. A method of assisted takeoff of an aerial vehicle, said method comprising: increasing output to an actuator of the aerial vehicle under a first control scheme, wherein the output to the actuator results in the increase of an altitude of the aerial vehicle; determining, with aid of a processor, whether the aerial vehicle has met a takeoff threshold based on the output to the actuator, the output measured from the actuator, or velocity or acceleration of the aerial vehicle, wherein determining whether the aerial vehicle has met the takeoff threshold is performed without (1) using signals from a source external to the aerial vehicle, or (2) using signals reflected to the aerial vehicle; and controlling the output to the actuator using a second control scheme when the aerial vehicle has met the takeoff threshold.
