Abstract
A method of assisted takeoff of a movable object includes increasing output to an actuator that drives a propulsion unit of the movable object under a first feedback control scheme, determining whether the movable object has met a takeoff threshold, and controlling the output to the actuator using a second feedback control scheme different from the first feedback control scheme in response to the movable object having met the takeoff threshold.
