What localization algorithm is used by Hello Stretch Robot?

Hello every body,
I would write an article about the localization algorithm used by Hello Stretch robot. I check the documents offered by Hello Robot but i could not find any mention about the localization algorithms used by the robot.
Is it Adaptive Monte Carlo Localization?

Hi @BdA_Alg, stretch_nav2 uses AMCL for localization. See nav2_params.yaml for more details on the default AMCL parameters that are used.
