gbaman built his Panobot using a Raspberry Pi and Lego.
I have just finshed work on version 1 of my Pi powered Panobot. It is a robot designed to take panoramas with the official raspberry pi camera board.
It is built out of lego and uses the same motors and motor controller as my Lego Pibot.
It runs a python script which allows me to program how wide a panorama I want and how many levels. Once the images are taken I copy them over to my laptop and stitch them together into one image using Hugin http://hugin.sourceforge.net/
The Pi camera is very good for its price but compared to my DSLR has a smaller dynamic range and also a smaller HFOV (Horizontal Field Of View) so to get a panorama, it requires a few more pictures. I found to allow enough overlap that 10 pictures wide was sufficient by 3 pictures tall. This totaled to 30 pictures per panorama compared to my normal 25 pictures for my DSLR. I have to stitch them on my laptop instead of the pi due to massive amount of processing power to find the control points
