While visiting around Danny's website, I found a few other interesting items...
Apparently, Danny's next project is to build a NXT version of the Star Wars AT-ST biped/walker. I think Danny may actually be further along than we imagine, because on the website you can see a green-outline of the prototype... not sure what graphics program is being used to do this, but it looks like it may actually exist... what do you think?
Finally, you can also download Danny's degree thesis paper titled "Lego Mindstorms - based mobile robots team" - a pdf written, I believe, in Italian. I can't read it, but there are plenty of pictures to look at :)
