[ros-users] simulator_gazebo 1.1.0 and pr2_simulator 1.0.2 released

[John Hsu]

In case anyone is interested in contributing to bullet debugging work, a
recommended starting world configuration is the
gazebo/gazebo-svn/worlds/simpleshapes.world that gets pulled into the gazebo
package during build.
Thanks,
John
