Hello everyone
I recently began using gazebo, (two days ago) and I have run into some problems that I hope someone can help me solve. I am using the SVN head version of gazebo together with OGRE 1.6.1 and ODE-0.11 on a Kubuntu 8.04 64-bit system. My first question has to do with the max range setting on the sicklms200 laser. I want to mimic my real laser that is set to scan up to 80 meters. When I set the max range in my gazebo .world file the “laser beams” in gazebo seems to have the correct length. But when I connect gazebo to a player server and us a client to read the laser data, all range readings are divided by 10. My maximum range will be 8 meters. If I set the max value to 20 meters in gazebo my maximum range from player will be 2 meters. If I set it to 9 meters the maximum will be 0.9 meters. BUT if I set it to 8 meters (the default value) the range readings are not divided by 10 and the correct ranges are given. Why does the “range unit” change depending on max range setting. This does not happen on my real laser. Second question: In the help files at the web page it is said that the GUI can be deactivated if you omit the <rendering:gui> section. When I do this Gazebo crashes with the following message: How do I make it work? [server/GazeboConfig.cc:84] Gazebo Path[/usr/local/share/gazebo] [server/GazeboConfig.cc:92] Ogre Path[/usr/lib/OGRE] gazebo: OgreTextureManager.cpp:43: static Ogre::TextureManager& Ogre::TextureManager::getSingleton(): Assertion `ms_Singleton' failed. Aborted Third question: I am using a client that is following a set of lines created between waypoints in the world coordinate system. Once it reach the end of the track the order of waypoints is reversed and the robot goes back to the beginning and so on. I have noticed after running the simulation for a few minutes that the track seems to have drifted. The question is. Does gazebo include drift, noise, uncertainty, or slip in the odometry calculations? (I am using a world file based on the pioneer2dx robot (with the addition of one laser). The client program is only using the odometry for positioning in the track.
