Hi, John: Sorry to bother you again. 1) I checked out pr2_2dnav_gazebo and put it under the corresponding folder of my installed ROS. say: /opt/ros/cturtle/stacks/wg_robots_gezebo/pr2_2dnav_gazebo When I do roslaunch "roslaunch pr2_2dnav_gazebo pr2-armless-wg-fake_localization.launch" I got 'ROBOT' is not set jiapei@jiapei-laptop:/opt/ros/cturtle/stacks/wg_robots_gezebo$ roslaunch > pr2_2dnav_gazebo pr2-armless-wg-fake_localization.launch > ... logging to > /home/jiapei/.ros/log/73e7b77a-bd42-11df-8314-0040d0a919ff/roslaunch-jiapei-laptop-4044.log > Checking log directory for disk usage.

And, why "pr2_2dnav_gazebo" is not packaged into Ubuntu repository for automatic installation? By the way, from the name of "ros-cturtle-simulator-gazebo", I'm guessing, by using "ros-cturtle-simulator-gazebo" only, am I able to simulate the robots navigation already, without checking out "pr2_2dnav_gazebo" ? Or, "ros" refers to the system without specifying a particular robot, while "pr2" is a specific robot. We have to specify a type of robot before its navigation? Sorry for my entry-level questions, but I really need your help.
