Regarding Segway robotics, I thought you might be interested to know that DARPA funded development of a Segway-based common robotics platform (the "RMP"): Link. A group at CMU is working on a Robocup robot soccer team using the Segway RMP: Link. One cool thing about their work is that it's the first robot soccer team (as far as I know) that can play with and against humans on the field. Unfortunately they don't seem to have any images/video of that online; I saw some video at a conference a few weeks ago.
Also, check out this origami folding robot at CMU: Link.
