Hi @Rafafbo ,

you should mention the code which you changed, like this:

https://github.com/lardemua/atom/blob/d6f163712974654dd1620c2a94743eea8ef798be/atom_calibration/package.xml#L12-L18

That way it is easier to understand ...

I would check the car xacro definition, in particular the place where hodometry is defined. There should be a way to define the name of the odom frame and change it to world.

In any case @manuelgitgomes will know more about this than me ...

Noted!

Yes, I checked it and didn't see any definition of the odom or the world frame.

Perhaps this

But only @manuelgitgomes will be able to help. He is quite busy now so probably will only reply next week...

Hello @Rafafbo.

Honestly, I am not certain how I did this and, as @miguelriemoliveira stated, I do not have the time to delve into this right now.

However, I found this:

<group if="$(arg calibration)">
<node name="model_states_to_tf" pkg="atlascar2_odom" type="model_states_to_odomtf.py"/>
<node name="controller_spawner" pkg="controller_manager" type="spawner"
args="$(find atlascar2_description)/config/atlascar2_steering_params.yaml">
</node>
</group>

When calibrating, for some reason, I use different parameters. Are you setting the arg calibration as true when launching?

Hello @manuelgitgomes

Yes, I tried but same issue with other frames and i don't understand why you made this transform:

br = tf2_ros.TransformBroadcaster()
t = TransformStamped()
t.header.stamp = rospy.Time.now()
t.header.frame_id = 'odom'
t.child_frame_id = 'base_footprint'

Anyway, don't worry about it now because I found another way to get good collections!
