<div>(Sorry to continue hijacking the GPS thread...)</div><div><br></div><div>For sure. I have actually been working largely from the tutorials, which are excellent, especially the rospy ones. But the tools tutorials seem to be a bit more aimed at understanding and contributing to established projects, rather than providing instruction on how to start from scratch.</div>
<div><br></div><div>For example, regarding path setup issues, the CreatingPackage tutorial has the reader use "rospack find" to ensure that the rosbash tools are aware of the new package that's been created. However, in a new package other than beginner_tutorials, this will fail due to problems with ROS_PACKAGE_PATH; the tutorial is great for getting going on beginning_tutorials (with its pre-cooked setup.sh file), but it's a bit incomplete if one is following it to start a new project.</div>
<div><br></div><div>In the future, I may be able to contribute some additional material from my notes, which would cover the questions related to our project that don't seem to be as explicit in the existing documentation.</div>

Mike, <div>I suggest you take a look at the ROS tutorials. They talk about how to setup and use your ROS environment etc. <a href="http://www.ros.org/wiki/ROS/Tutorials" target="_blank">http://www.ros.org/wiki/ROS/Tutorials</a> </div>

</div>You need to update your ROS_PACKAGE_PATH. The python path is<br>
automatically taken care of if you setup your <depend> tags correctly<br>
in your packages' manifest.xml (and call<br>
roslib.load_manifest('mypackage'))<br>
