How can I stop the map rotating

edit

I trying to mapping. my rplidar is a2, and using hector slam and my robot is a drone.

this link is my mapping test video

that is wrong

probably I think that rplidar or drone don't recognize the direction of my robot during drawing the map

I want to drawing the map like this link

https://youtu.be/pCF7P7u8pDk

I use default launch file in rplidar_ros, hector_slam

(rplidar_ros/launch/view_rplidar.launch & hector_slam/hector_mapping/launch/mapping_default.launch)

my tf tree picture

If rplidar knows the direction of rotation of the drone, I can solve it.

but I don't know the way of it

How can I get some rotating direction information of drone?

or is it problem that rotating rplidar?

please some advice

I have to solve this problem .

What is hector_pose_estimation ? What is the purpose and how do I use it?
