The moving parts

Now that I have the basic sensors working, I've decided to look into developing an idea for how I want the tortoise to be structure and how that structure should move.  My interest is in making the tortoise move in a fashion that is closer to that of a real tortoise than to a radio controlled car.  That means I will have to figure out how to construct four moving legs and a long neck capable of retracting into its shell.  Currently, I'm in research mode on this, but when I get some ideas, I'll blog some more.
