CHAPTER 7StringBot—Build It
Figure 7-1 shows my version of the StringBot. It's a strange-looking device, but it does work. If you ever want to have some fun, try showing your bot design to others who are unfamiliar with it. Ask them "What do you think it does?" and be ready for some surprising answers! I showed this to a couple of people and the most surprising response was this: "How does it roll along the floor with only one wheel? The smaller wheels don't look like they'll help hold it up." Just goes to show that you cannot judge a book (or a bot, in this case) by its cover.
