I originally put together this document for a school group that was coming to CMU for a tour of the Robotics Institute. In my experience, many students come on these tours without any clear ideas of what research in robotics is about or why robotics is difficult..
This document contains a number of questions and exercises which can be used for students at various levels. There is a lot of material, so you can pick and choose according to your time and students' interests.
You should consider this document to be a first draft.
I don't have a lot of time in the near future to revise this document, but if someone wanted to do some revisions or to add some material, that would be great.
