[ros-users] Erratic_gazebo

Tue Nov 2 12:07:30 UTC 2010

Hi,

Thanks for answering, I am stilling having problems, I have done:
In ros directory I have execute the following instruction:
svn co https://code.ros.org/svn/wg-ros-pkg/trunk wg-ros-pkg-unreleased

Then I have add in the ROS_PACKAGE_PATH the directory where I have done the instruction shown above, so the setup.sh is:

export ROS_PACKAGE_PATH=/home/nicolas/ros/ros:/home/nicolas/ros/stacks/wifi_drivers:/home/nicolas/ros/stacks/wg_pr2_apps:/home/nicolas/ros/stacks/wg_hardware_test:/home/nicolas/ros/stacks/wg_common:/home/nicolas/ros/stacks/web_interface:/home/nicolas/ros/stacks/vslam:/home/nicolas/ros/stacks/visualization_tutorials:/home/nicolas/ros/stacks/visualization_common:/home/nicolas/ros/stacks/visualization:/home/nicolas/ros/stacks/vision_opencv:/home/nicolas/ros/stacks/trajectory_filters:/home/nicolas/ros/stacks/tabletop_object_perception:/home/nicolas/ros/stacks/sql_database:/home/nicolas/ros/stacks/sound_drivers:/home/nicolas/ros/stacks/slam_karto:/home/nicolas/ros/stacks/slam_gmapping:/home/nicolas/ros/stacks/simulator_stage:/home/nicolas/ros/stacks/simulator_gazebo:/home/nicolas/ros/stacks/roslisp_support:/home/nicolas/ros/stacks/ros_tutorials:/home/nicolas/ros/stacks/ros_realtime:/home/nicolas/ros/stacks/robot_model:/home/nicolas/ros/stacks/robot_calibration:/home/nicolas/ros/stacks/pr2_web_apps:/home/nicolas/ros/stacks/pr2_tabletop_manipulation_apps:/home/nicolas/ros/stacks/pr2_simulator:/home/nicolas/ros/stacks/pr2_self_test:/home/nicolas/ros/stacks/pr2_robot:/home/nicolas/ros/stacks/pr2_power_drivers:/home/nicolas/ros/stacks/pr2_plugs:/home/nicolas/ros/stacks/pr2_object_manipulation:/home/nicolas/ros/stacks/pr2_navigation_apps:/home/nicolas/ros/stacks/pr2_navigation:/home/nicolas/ros/stacks/pr2_mechanism:/home/nicolas/ros/stacks/pr2_kinematics_with_constraints:/home/nicolas/ros/stacks/pr2_kinematics:/home/nicolas/ros/stacks/pr2_gui:/home/nicolas/ros/stacks/pr2_ethercat_drivers:/home/nicolas/ros/stacks/pr2_doors:/home/nicolas/ros/stacks/pr2_controllers:/home/nicolas/ros/stacks/pr2_common_actions:/home/nicolas/ros/stacks/pr2_common:/home/nicolas/ros/stacks/pr2_cockpit:/home/nicolas/ros/stacks/pr2_calibration:/h

But then when I want to do a rosmake in the directory 

nicolas at blanc:~/ros/ros$ rosmake erratic_gazebo
[ rosmake ] Packages requested are: ['erratic_gazebo']                          
[ rosmake ] Logging to directory/home/nicolas/.ros/rosmake/rosmake_output-20101102-131102
[ rosmake ] Expanded args ['erratic_gazebo'] to:
[]                             
[ rosmake ] WARNING: The following args could not be parsed as stacks or packages: ['erratic_gazebo']
[ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.

I dont have a clue of what I should do!! If someone can help me I will be grateful.

Hi folks,
The erratic_gazebo_plugins package only provides a differential drive controller for the simulated robot. Actual robot urdf description, 3D meshes and some sample launch files are in http://www.ros.org/wiki/erratic_description package.

Nicolás, you can follow instructions on our wiki page to install ua-ros-pkg repo here: http://code.google.com/p/ua-ros-pkg/wiki/DeveloperInstall. It assumes you are doing a fresh svn based install. Let me know if you run into any trouble.

Hi Nicolás,

There are multiple ways to locate this package:

$ roslocate svn erratic_gazebo

https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle/stacks/wg_robots_gazebo/erratic_gazebo

On the wiki page, look for "Source: svn"

http://www.ros.org/wiki/erratic_gazebo

However, I'll note that the erratic packages will soon be taken over

by those provided by ua-ros-pkg, as they are better maintained. I

believe their equivalent package is:

http://www.ros.org/wiki/erratic_gazebo_plugins

I've also patched roslaunch (r11979) to not have as bad of an error

message when this occurs.

cheers,

Ken
