Hi, I am faced with the same problem. I use a turtlebot2 with Kinect XBOX 360. The output from "view_frames" is similar to your output, /openni_depth_frame is not connected to /camera_link. Could you explain how did you solve your problem in more detail?

Thanks, Jorge. I found the priority parameter 5 on turtlebot_bringup/param/mux.yaml, and the priority parameter 7 on kobuki_keyop/param/keyop_mux.yaml. Then if I use kobuki_keyop, the navigation works.

I could not find the priority of "2D Nav Goal" on Rviz. But I found that when I run "rosnode info /mobile_base_nodelet_manager ", then "/cmd_vel_mux/input/navi_raw" follows "topic: /cmd_vel_mux/input/teleop". on Connections. Does the writing order mean the priority?

Thanks for your help. I found that after I launched "turtlebot_teleop", six zero parameters(linear and angular xyz) are published on topic "/mobile_base/commands/velocity" when I did not input any command. And in param/mux.yaml, the "Teleoperation" priority is 7.

I'm sorry, there are some typo. terelp means teleop, and tereop means teleop.

Thanks. I check it using "rqt_graph". But when I run the terelp, I found only /turtlebot_tereop_keyboard node communicated to /mobile_base_nodelet_manager node on /cmd_vel_mux/input/tereop topic. /map_server node, /move_base node and /mobile_base_nodelet_manager still communicate. Why don't work?

Hi, I solved it by myself.

The reason why I could not use the autonomously plan is that I did not stop the teleoperation when I use the "2D Nav Goal" command, roslaunch turtlebot_teleop keyboard_teleop.launch

Then, after "2D Pose Estimate" and localization by teleoperation, I should stop the teleoperation command.

After stopping teleoperation, "2D Nav Goal" command works well!

Hi, I'm totally new in ROS-Groovy and turtlebot 2(Kobuki) on Ubuntu 12.04(64bit). I followed TurtleBot tutorials, section 1 to 3 were OK. But I met some difficulties with basic tutorial about "Autonomous Navigation of a Known Map with TurtleBot".

I generated a my_map following the previous tutorial, "SLAM Map Building with TurtleBot". After that, I loaded my_map and "roslaunch turtlebot_rviz_launchers view_navigation.launch". I could Localize the TurtleBot using "2D Pose Estimate" and Teleoperation. But when I Clicked the "2D Nav Goal" button and set a Goal, my turtlebot didn't move anywhere. Can anyone help me?

I found some warnings when I ran "roslaunch turtlebot_navigation amcl_demo.launch map_file:=/tmp/my_map.yaml". The warnings are,

: You have set map parameters, but also requested to use the static map. Your parameters will be overwritten by those given by the map server

: Trajectory Rollout planner initialized with param meter_scoring not set. Set it to true to make your settins robust against changes of costmap resolution.

And I also checked the status by "rqt -s kobuki_dashboard", after set a Goal, I found a warning that "Using odometry instead of last command" every frame.
