Hello, I ran your code successfully before, but i met an error these days.

  1. When i run "roslaunch turtlebot_exploration_3d minimal_explo.launch", it shows a [WARN]: setting /run_id to cb9f3338-dbef-11e8-a8ab-00367664b761 process[rosout-1]: started with pid [11178] started core service [/rosout] process[robot_state_publisher-2]: started with pid [11196] process[diagnostic_aggregator-3]: started with pid [11197] process[mobile_base_nodelet_manager-4]: started with pid [11198] process[mobile_base-5]: started with pid [11205] process[bumper2pointcloud-6]: started with pid [11214] process[cmd_vel_mux-7]: started with pid [11220] process[turtlebot_laptop_battery-8]: started with pid [11222] process[capability_server-9]: started with pid [11232] process[app_manager-10]: started with pid [11240] process[master-11]: started with pid [11252] process[interactions-12]: started with pid [11276] process[zeroconf/zeroconf-13]: started with pid [11285] [ INFO] [1540868361.765459318]: Zeroconf: service successfully established [turtlebot][_ros-master._tcp][11311] [WARN] [WallTime: 1540868363.614965] Rapp Manager : 'rocon_apps/chirp' is not unique and has no preferred rapp. rocon_apps/meow_chirp' has been selected.

  2. When i run "roslaunch turtlebot_exploration_3d turtlebot_gmapping.launch", it can not find kinect: [ INFO] [1540868420.788991651]: Initializing nodelet with 4 worker threads.

Waiting for your help, thank you.

Met the same issue on kinetic

Sorry for my late reply, for the "2nd" problem it seems like the driver of the Kinect sensor, this could happen for many reasons and most of the time the easiest fix is to reinstall the driver...unfortunately... For the first one, I am not sure what is the cause, however since it is a "WARN", is it affecting the mapping motions?

For the first problem, I find that when I run "roslaunch turtlebot_bringup minimal.launch" before running "minimal_explo.launch", the [WARN] will disapper. So I compare "minimal_explo.launch" with "minimal.launch". The diferrence between the two is "" . "minimal_explo.launch" does not include this arg. I wonder if it lacks this arg?

sorry, your previous post did not show the "arg" you were referring to. Seems you have solved the problem, so I am closing this ticket. Feel free to reopen if you run into same errors again or just open a new one if you run into a new error. Thanks.
