notes from Acorn

[isucan]

• If we do another demo where we require a certain version of ros from a certain repo, we need to provide instructions on how to get to that state
• It is not clear how to create pr2.urdf. There is a link to http://moveit.ros.org/wiki/index.php/Groovy/URDF which is confusing: most of that is not needed for the tutorial, but the 2 line command that installs ros-groovy-pr2-common and runs xacro is needed. Or else if the file is available in some standard place we need to mention where that standard place is.
• Most of the boxed comments on the wiki are shell commands or contents of files which need to be created. But there are also some other uses. These are confusing and people tried to copy/paste them to the shell. Should remove these or somehow mark them so they look different
• several people were confused by the last step in setup assistant where they have to create a directory and then open that directory. Selecting directory names that do not exist yet is unintuitive in the file dialog.
• People had trouble setting FixedFrame because just below the field they need to set is another field also named FixedFrame which is bright red until the fixed frame is set correctly. Maybe rename one of these fields?
• remembering to source ~/moveit/devel/setup.bash was troublesome for some people not used to ROS.
