Hi, thanks for confirming. 2018-04-10 16:47:35 -0500 marked best answer Change (display) representation of orientation of model. Hi, Currently Gazebo displays ( in the left panel as shown below ) the orientation ( Roll , Pitch and Yaw ) of a model in radians. Please see image if required. I have a few related questions - Is it possibe to convert the Roll pitch and yaw to degrees (Mainly for convenience) ? Is it possible to change the representation to a quaternion ( q_x, q_y, q_z, q_w ) ? Thanks! 2018-04-10 16:47:26 -0500 commented answer Change (display) representation of orientation of model.

Hi, I am currently working on a drone related project and using gazebo for simulation In order to measure accuracy of my localisation, I need to know the ground truth values. Is there some way in Gazebo to continuously track/store the actual/true/ground truth 6D pose, ie the rotation and translation w.r.t. to a fixed frame like the world frame. I wish to create something like the following - Thanks a lot ! 2018-04-10 06:43:53 -0500 answered a question Continuously Tracking and storing 6D pose of an object in Gazebo simulation.

Hi yes I am using Gazebo + ROS , but I needed a topic that provides both - the ground truth and timing values. 2018-04-10 03:56:29 -0500 received badge ● Notable Question (source) 2018-04-09 16:32:04 -0500 commented answer Continuously Tracking and storing 6D pose of an object in Gazebo simulation.

I believe this may be due to  in XML below. Question: I have been following this tutorial to simulate a Kinect in Gazebo and then publish image,pointcloud etc to ROS topics. However, rostopic list does not show the required topics in the output. I have also looked at the following questions on this forum - this and this. The issue in the first one seems to be same as mine. The person suggested to use URDF files instead (which I will try but would still like to know why below approach is not working ). Here is the relevant XML code for the model.sdf file in the kinect directory that I have modified according to the tutorial mentioned above -  //some xml true 20 1.047198 640 480 R8G8B8 0.05 3 0.2 true 0.0 camera_ir /camera/depth/image_raw /camera/depth/camera_info /camera/depth/image_raw /camera/depth/camera_info /camera/depth/points camera_link 0.05 0 0 0 0 0 0 0 0 0 0 // some more xml  I would like to mention the following - Note that in the XML code - The plugin is defined as a sensor plugin (I am aware that model and sensor plugins are different things in Gazebo and it can lead to an error if the right one is not used.) I have been using the command - roslaunch gazebo_ros empty_world.launch to open the world.I then manually add the kinect model shown above. I have also tried rosrun gazebo --verbose and I get a warning - [Wrn] [msgs.cc:1655] Conversion of sensor type[depth] not suppported. Also, output of rostopic list after launching gazebo and adding the kinect ( Sorry unable to format this as code for some reason ) - /clock /gazebo/link_states /gazebo/model_states /gazebo/parameter_descriptions /gazebo/parameter_updates /gazebo/set_link_state /gazebo/set_model_state /rosout /rosout_agg I have checked rostopic echo /clock , which means the Gazebo simulation is running. o I need to install that plugin libgazebo_ros_openni_kinect.so ? This seems more like an issue on the Gazebo side and hence I have posted here ( instead of ROS forum. ) Thanks a lot !
