Hi All, simulator_gazebo 1.1.3 and pr2_simulator 1.1.0 have been released. This is an unstable release and contains a lot of improvements to the gazebo GUI as well as new ROS API to simulation. Please see the ChangeLists for more information: http://www.ros.org/wiki/pr2_simulator/ChangeList http://www.ros.org/wiki/simulator_gazebo/ChangeList Some of the more notable changes are * gazebo is now a ROS wrapped binary * dynamic plugins library paths are located automatically through export tags in manifest.xml (vs. setting LD_LIBRARY_PATH previously). For tutorials on the new proposed ROS API, please see this page: http://www.ros.org/wiki/simulator_gazebo/Tutorials/Gazebo_ROS_API Any comments / suggestions are welcome. Thanks, John
