<div><br></div><div><br></div><div>2) My 2nd question is I found I've installed "ros-cturtle-simulator-gazebo",</div><div>I'm wondering what are the connections between "pr2_2dnav_gazebo" and "ros-cturtle-simulator-gazebo" ?</div>
<div>And, why "pr2_2dnav_gazebo" is not packaged into Ubuntu repository for automatic installation?</div><div><br></div><div>By the way, from the name of "ros-cturtle-simulator-gazebo",</div><div>I'm guessing, by using "ros-cturtle-simulator-gazebo" only,</div>
<div>am I able to simulate the robots navigation already, without checking out "pr2_2dnav_gazebo" ?</div><div>Or, "ros" refers to the system without specifying a particular robot,</div><div>while "pr2" is a specific robot.</div>
<div>We have to specify a type of robot before its navigation?</div><div><br></div><div>Sorry for my entry-level questions, but I really need your help.</div><div><br></div><div><br></div><div>Best Regards</div><div>JIA</div>

Hi JIA,<br>Sorry, my mistake, wg-ros-pkg trunk has been moved to branches/trunk_cturtle.
