Hi,

when I run turtlebot simulation, there is no simulated Kinect. I'm sure that before some time it was working.

I'm using this command to run simulation:

roslaunch turtlebot_gazebo turtlebot_empty_world.launch
List of topics which are advertised:
/clock
/cmd_vel
/diagnostics
/diagnostics_agg
/gazebo/link_states
/gazebo/model_states
/gazebo/parameter_descriptions
/gazebo/parameter_updates
/gazebo/paused
/gazebo/set_link_state
/gazebo/set_model_state
/imu/data
/joint_states
/odom
/robot_pose_ekf/odom
/rosout
/rosout_agg
/scan
/tf
/turtlebot_node/sensor_state

During start-up there is just this info (from pointcloud_throttle, kinect_laser and kinect_laser_narrow nodes):

waitForService: Service [/openni_manager/load_nodelet] has not been advertised, waiting...

Thanks for any advice...

what version of turtlebot, turtlebot_simulator, and turtlebot_apps do you have installed?

I have the latest installed from the repositories on ROS Electric on Ubuntu 11.10.

This is a bug in the gazebo.urdf.xacro file. The camera frame names were not correct and therefore the gazebo plugins couldn't initialize properly. It's fixed in 330:4253a4e5f257 . It's released in turtlebot 0.9.2

Hello,

I'm new to the whole ROS thing. I just started exploring it. I am also having problems with Kinect data in turtlebot_gazebo simulation. I'm using Ubuntu 10.04 and ROS Electric.

I've managed to get kinect topics advertised with adding this line to the launch file.

<!-- openni_manager -->
<node pkg="nodelet" type="nodelet" name="openni_manager" output="screen" respawn="true" args="manager"/>

But I still have the problem that Kinect is posting no messages. Maybe you will find out why.

I hope it helps you.
