Thanks, I found two robotic arms there. Neither was the one I was looking for. However, they both look cool and could work for my demonstration, but my laptop is only a 1 GHz with 384 MB of RAM so I loaded the oldest version of Inventor I could find, INV 4. Attached is an AVI of the arm I was trying to use, but the files are too old to even be read by INV 4.
