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. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.
environment variable 'ROBOT' is not set
Then, I set 'ROBOT' as "PR2" (I just guessed this, how to set this environment variable? )
This time, I obtained "Invalid roslaunch XML syntax: [Errno 2] No such file or directory" .
jiapei@jiapei-laptop:/opt/ros/cturtle/stacks/wg_robots_gezebo$ export ROBOT=PR2
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/db1290a0-bd42-11df-b443-0040d0a919ff/roslaunch-jiapei-laptop-4091.log
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.
while processing /opt/ros/cturtle/stacks/wg_robots_gezebo/pr2_2dnav_gazebo/2dnav-stack-fake_localization.launch:
while processing /opt/ros/cturtle/stacks/pr2_navigation/pr2_navigation_global/move_base.xml:
while processing /opt/ros/cturtle/stacks/pr2_common/pr2_machine/PR2.machine:
Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'/opt/ros/cturtle/stacks/pr2_common/pr2_machine/PR2.machine'
So, my first question is: How to set 'ROBOT' for this pr2 2D navigation simulation?
2) My 2nd question is I found I've installed "ros-cturtle-simulator-gazebo",
I'm wondering what are the connections between "pr2_2dnav_gazebo" and "ros-cturtle-simulator-gazebo" ?
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.
Best Regards
JIA

Hi JIA,
Sorry, my mistake, wg-ros-pkg trunk has been moved to branches/trunk_cturtle. I've updated the svn command accordingly:
svn co https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle/stacks/wg_robots_gazebo/pr2_2dnav_gazebo

Hi, John:
Sorry that I couldn't make it work yet.
It seems I'm not able to check out "pr2_2dnav_gazebo".
jiapei@jiapei-laptop:~$
Any further suggestions?
Best Regards

Hi JIA,
I've fixed the tutorial page to include where to get pr2_2dnav_gazebo.
Please let me know if you can test the nav stack successfully in sim.
thanks,
John
Hi, all:
Sorry for my amateur question.
I'd love to try out some simple robot control demos of ROS.
but it seems the tutorials here are too old and
I failed to find pr2_2dnav_gazebo (but pr2_2dnav found),
and pr2-simple-fake_localization.launch doesn't existing at all.
So, can anybody please show me
where to find a runnable robot navigation or robot control demo of ROS,
including the source code,
so that I may be able to revise the source according to my own control requirement?
Thanks in advance.
Best Regards
JIA
