Hello from Stephanie Lindsay, the lucky editor at Parallax Inc. I’ve just posted Chapter 7 of Robotics with the BOE Shield for Arduino. With IR LED/receiver pairs, the BOE Shield-Bot can detect obstacles and navigate around them. In this video clip the strategy is reversed – avoid open space instead of obstacles – so the Shield-Bot can drive around on a tabletop without falling off.
I’m having SO much fun learning about the Arduino as I test-drive and edit this book. The last chapter, Robot Control with Distance Detection, is coming up next week. Almost done!
