Ahhh... This is the part of Build Season I "love" the most: getting the Inventor file structure straightened out after a month of people moving things around.

First: Are the folders you've put the part files in in the path specified in the Project Workgroup Search Paths list? (Open->Projects->Workgroup Search Paths) If you are using the Default project, you probably don't have a workgroup search path listed; if you are using a project created for the robot design (like you should...) you will probably see a path to the directory that the files should reside in. If the new part folders are not in that directory or in sub-directories of it (folders inside the top folder), you need to either add the new folder paths to the search paths list, or move the folders inside the specified one. Otherwise you will always have Inventor confused (even more than usual).

If the paths are okay and you still have the problem, post back and I'll see what I can do to help further.

For more info on how this stuff should be set up, I suggest you start with the tutorials found at Open->Getting Started->Learn About Projects. More info specific to this problem may be found in the Inventor help files by searching for the "search paths" keyword.
