CHAPTER 25 ■ LAUNCHING THE LINE-FOLLOWERFigure 25-13. Left to right: Sandwich, Blue Sandwich, and Red Sandwich
Final Bow
I hope you’ve enjoyed reading about Sandwich. Hopefully, you’ve even built one of your own.
If your robot isn’t working as well as you’d like, don’t get frustrated. Every great scientist anticipates and
appreciates the opportunity for learning from every point of failure. The investment you make objectively
examining this robot is actually time spent planning your next robot.
To that end, there were actually three Sandwich robots built while originally writing this book
(see Figure 25-13). Each one consists of improvements I made from observing the advantages and
disadvantages of the prior one. The improvements were then worked back into the book, so that you, the
reader, see the most advanced design.
Now that you’ve been introduced to the fundamentals of robot building, where do you go from here?
That’s what the next couple of chapters are all about.
