A while back I "discovered" stepper motors, when my eBay package with 2 little 28BYJ-48 steppers and 2 ULN2003 drivers arrived. Given a total price of less than $8 shipped, I figured there is not much to loose. I have to say that I am quite impressed with the result. Steppers, even cheap ones like these, seem to be great for small robot projects where you want some more accuracy in performance, but do not want to implement a complex closed loop systems with wheel encoders, accelerometers and gyros. Here is a quick video of the result:

I posted more details, wiring diagrams and Arduino code (using the AccelStepper library) on my blog:
