Training unit errors/updates/omissions

[shaun-edwards]

• [x] Item 2.1 in training unit 1.3: roscd show calibration_msgs should be roscd calibration_msgs
• [x] Item 2.2-1 in training unit 1.5: Source file line reads STEP 2, not step 3
• [x] MoveIt links in training unit 3.3: MoveIt wiki links are broken.
• [x] MoveIt links in training unit 3.4: MoveIt wiki links are broken.
• [x] MoveIt modifications for ROS-I needs updated training unit 3.4: ROS-I tutorial and exercise no longer match. Controller manager template file no longer exists. Should we update this to the simple controller manager or just update the exercise with the old templates?
• [x] Import object fails on virtual machine (with graphics acceleration disabled) in training unit 3.5: Added note to use Import URL instead
• [ ] Item 2.1 in [training unit 3.6](http://aeswiki.datasys.swri.edu/rositraining/Exercises/3.6] Move to name position broken.
• [x] MoveIt links in [training unit 3.6](http://aeswiki.datasys.swri.edu/rositraining/Exercises/3.6] MoveIt wiki links are broken.
• [x] Git source download out of date in training unit 4.1 Modify git source section to utilize an existing package.

in unit 4.1 (but possibly also in other units) the devel branches in the github repositories are refered to as groovy_devel (for Groovy). It should be groovy-devel (note the dash, instead of an underscore).

The steps in 4.1 also do not source either a workspace or the main distro setup.bash (but perhaps this is already explained in other units?).

We may need to rethink section 4.1. The use of catkin is new to the tutorials and doesn't really fit. I only added it because I wanted to demonstrate a git repo. Unfortunately we don't have a rosbuild git repo. FYI...the steps in 4.1 work because the "training_unit" command sources a setup file. These are all things we should consider when porting everything to catkin.

I fixed the MoveIt wiki/API links. The 3.6 training lesson seems to work fine for me. That named position target ("straight up") is defined in the moveit package created for that exercise. Perhaps you were using a different MoveIt config? Feel free to close this issue when you've verified that last issue.

using the ros-industrial training disc image and running

training_unit demo_manipulation catkin_make

leads to dependency issues for me see: https://groups.google.com/forum/#!topic/swri-ros-pkg-dev/bNFCpZc5Xmw
