{"command":"get_trajectory_file_list","page_num":1,"page_size":10,"vague_search":"file"}

Output

{"command":"get_trajectory_file_list","list":[{"create_time":1737457680183,"name":"test2","point_num":501},{"create_time":1737458013270,"name":"test1","point_num":501}],"total_size":2}

Start Running Specified Trajectory set_run_trajectory_file

• Input Parameter

Parameter	Type	Description
set_run_trajectory_file	string	Start running the trajectory with the specified ID.
name	string	Run the trajectory with the specified name, which must exist and be runnable.

• Output Parameter

Parameter	Type	Description
start_state	bool	Execution parameter for the trajectory command: true: Start running successfully, false: Failed to run.
trajectory_file_state	string	Parameter indicating the trajectory file has been executed to its final position.

• Code demo

Input

Start running the trajectory named "123".

{"command":"set_run_trajectory_file","name":"123"}

Output

Start running successfully.

{
    "command": "set_run_trajectory_file",
    "run_state": true
}

Start running failed.

{
    "command": "set_run_trajectory_file",
    "run_state": false
}

After the trajectory reproduction is completed, it returns the trajectory execution completion command.

Output

Deleted successfully:

{
    "command": "delete_trajectory_file",
    "delete_state": true
}

Failed to delete:

{
    "command": "delete_trajectory_file",
    "delete_state": false
}
