  1. Please describe the issue in detail.
    I am currently facing this above issue ,here I am using Cartographer localization instead of AMCL to localize the robots.Because of this exploration error the motion of the robots is not continuous . what should I change to eliminate this error also I am using 2 robots one is equipped with an LDS 01 sensor and the other with an LDS 02 sensor the frequency with which the exploration error occurs is much lesser in the LDS 02 sensor ,I have been stuck with this problem for quite some time would be great if I can get some assistance on this
