if the remaining energy of the moveable object is not capable of supporting the moveable object in completing the task that has not been completed in the at least two to-be-executed tasks and returning, sending a prompt warning of insufficient energy to a control terminal.

6. The method according to claim 5, further comprising:

determining whether the number of times of sending the prompt warning of insufficient energy to the control terminal exceeds a preset threshold; and

if the number of times or the duration of sending the prompt warning of insufficient energy to the control terminal exceeds the preset threshold, canceling execution of the task that has not been completed and returning.

7. The method according to claim 1, wherein the executing the at least two to-be-executed tasks according to the determined task mode comprises:

determining, when one of the at least two to-be-executed tasks is completed, whether there is a new task needing to be added to the task list; and

if there is a new task needing to be added to the task list, updating the task list.

8. The method according to claim 1, wherein the executing the at least two to-be-executed tasks according to the determined task mode comprises:

determining, when one of the at least two to-be-executed tasks is completed, whether the moveable object has completed all to-be-executed tasks of the at least two to-be-executed tasks.

9. The method according to claim 8, wherein the task mode is the task set mode, and the method further comprises:

re-planning a path, and executing the task that has not been completed in the updated task list according to an optimal path.

10. The method according to claim 9, wherein the, determining, when one of the at least two to-be-executed tasks is completed, whether the moveable object has completed all to-be-executed tasks of the at least two to-be-executed tasks comprises:

determining whether there is a task that has not been executed by the moveable object in the task list; and

if there is no task that has not been executed by the moveable object in the task list, determining that the moveable object has completed all the to-be-executed tasks in the task list.

11. The method according to claim 8, wherein the task mode is the task flow mode, and the updating the task list comprises:

listing the new task at the end of the task list.

12. The method according to claim 11, wherein the determining, when one of the at least two to-be-executed tasks is completed, whether the moveable object has completed all to-be-executed tasks of the at least two to-be-executed tasks comprises:

determining whether a task currently executed by the moveable object matches a last executed task in the task list; and

if the task currently executed by the moveable object matches the last executed task in the task list, determining that the moveable object has completed all the to-be-executed tasks in the task list.

13. The method according to claim 1, wherein the executing the at least two to-be-executed tasks according to the determined task mode comprises:

determining whether the task list has two tasks that interfere with each other; and

if the task list has two tasks that interfere with each other, selecting a task mode again.

14. The method according to claim 1, wherein the at least two to-be-executed tasks are at least two of the following tasks:

disaster pre-warning, surveying and detection, image collection, detection and tracking, sample extraction and goods delivery.

15. A moveable object, comprising:

a body; and

a processor, which is disposed in the body, wherein

the processor is configured to;

obtain a task list, wherein the task list comprises at least two to-be-executed tasks;

determine a task mode, wherein the task mode comprises a task set mode and a task flow mode, the task set mode refers to that the moveable object executes the at least two to-be-executed tasks according to an optimal path, and the task flow mode refers to that the moveable object executes the at least two to-be-executed tasks according to a user-specified sequence; and

control, according to the determined task mode, the moveable object to execute the at least two to-be-executed tasks.
