1.roslaunch my bringup. 2.roslaunch hectormapping.launch 3.roslaunch rplidar.launch 4.roslaunch exploration_planner.launch 5.rosrun simple_exploration_controller

and then the trajectory is right,but the robots go opposite direction.

Hi @LGK199408 , very nice to see you are able to make roslaunch exploration_planner.launch working without an error message.

A group of people in #23 are suffering a timeout error:

[ERROR] [1582991686.126575728, 1172.588000000]: Do not call canTransform or lookupTransform with a timeout unless you are using another thread for populating data. Without a dedicated thread it will always timeout. If you have a seperate thread servicing tf messages, call setUsingDedicatedThread(true) on your Buffer instance.

We were wondering if you could teach us how to solve the error.

Best, -- Luke
