    • [ WARN] [1694953047.933345462, 1156.474000000]: No laser scan received (and thus no pose updates have been published) for 1156.474000 seconds. Verify that data is being published on the /robot1/scan topic.

  8. Please describe the issue in detail.

    • I am working multi robot on simulation Using ROS noetic . All seems fine but some reason the Amcl package brings out the error above . The laser tf tree seems fine . Laser scan publishes data . But for some reasons Amcl cant get the initial pose of the robot due to the error above . Screenshot below :

I solved this problem. I had to tweak the source code . Since the ros::Duration was greater than my laser scan interval the warning messages pops up and my robot scan topics will not receive scan data . So I had to make changes to that method.

Dear @Daviesss, Firstly, could you please provide the solved modified source ? Lastly, did you try to implement the multi robots in real environment?
