2014-01-28 17:27:11 -0500 | marked best answer | Joint::GetLinkForce() gets segmentation fault Hi, Has anybody used Joint::GetLinkForc() or Joint::GetLinkTorque in gazebo simulator? I am using them in a gazebo plugin and these functions give me segmentation fault. Thanks, |
2014-01-28 17:26:57 -0500 | marked best answer | How to use a gazebo plugin Hi, I have written a simple gazebo world plugin and compiled it (following the tutorial). Now I am not sure how to use this plugin. I am using ROS fuerte on Ubuntu 12.0.4. Is there a tutorial to explain it? Can I simply add a plugin tag into the .world file? Thanks, |

2014-01-28 17:26:44 -0500 | marked best answer | "unmet dependencies" error when installing ROS on ubuntu12.04 Hello, I have recently upgraded to Ubunto 12.0.4 and trying to reinstall ROS (Fuerte version). I have got the following error message. Even installing each package separately doesn't help. It seems that I am stuck inside a loop of dependencies. p.s. Still I have the old version of ROS on my computer; No idea how to get rid of it. sudo apt-get install ros-fuerte-desktop-full

2013-01-08 09:15:50 -0500 | marked best answer | ImportError: No module named rospkg Hello All, After installing ROS on my Ubuntu, I was trying to follow the tutorials under the simulator_gazebo. But I have gotten an error message for this command: Error message: Could it be from the installation? I think everything went well during the installation. Any thoughts? Thanks, |

2012-09-15 01:50:43 -0500 | marked best answer | Problem with spawn_model in gazebo Hello, I am trying to spawn a table and a coffee cup into the empty world of pr2 following this tutorial http://www.ros.org/wiki/pr2_simulator/Tutorials/BasicPR2Controls: The result is so weird, the table was spawned with no color(same color as the background) while I have gotten the error message: "filename referred by mesh [table.stl] does not appear to exist." The coffee cup was shown in the list of models but there is no coffee cup in the world. And there some error messages for this command : "namespace error : Namespace prefix model on physical is not defined" Why do I get these error messages? And if I delete one object from the world, the entire gazebo window will be closed. Why? p.s. I am working with Fuerte ROS on Ubuntu 12.0.4 Thanks, |
