This edition contains all five of the bots from the original edition, fully updated to EV3. Importantly, Jim Kelly’s story line is preserved. Now, let’s make a distinction here: the difference between what a bot does and how it does it. Since my five bots support Jim’s story, they perform the same “what they do.” But how shall they do it? These are new designs, leveraging Jim’s, and taking advantage of new EV3 features. And, added to this edition are a dozen Engineering sidebars with explanations of real-world engineering principles and processes.
