Question after launch

[Crystal-Biru]

When I start "roslaunch tmrrt_exploration trio_exploration.launch", no exploration screen appears, only the following information is repeated, I wander is there any error?

Hi Crystal-Biru,

I believe the merged map is not available for the exploration stack. Can you check whether the merge map is available? You may check using rostopic echo or hz.

[Crystal-Biru]

After using rostopic hz, only 'no new messages" showed: zbr@zbr-HKF-WXX:~/catkin_explore$ rostopic hz map subscribed to [/map] no new messages no new messages no new messages no new messages no new messages no new messages no new messages no new messages no new messages no new messages no new messages

Most probably you did not run the map merger or something wrong with it. Please check whether it is running or not.

More details of the map merger can be found here.

Thank you for your reply! I tried to use the code and follow the instructions from TM-RRT_exploration_Simulation, and the project ran successfully.

Great!
