Abstract: A method for controlling a movable object in an environment includes in response to a loss of signal between the movable object and a terminal of the movable object, controlling the movable object to return, including: controlling the movable object to move from a current location to a first location, receiving, through at least one of a plurality of sensors, sensing data of the environment, and controlling the movable object to move from the first location to a second location based on the sensing data. The first location is previously traveled by the movable object. A movement path from the current location to the first location is associated with a movement path from the first location to the current location.
