Appendix B. SPOT Building Instructions

You can always create a custom robot of your own to use while performing the exercises in this book, but I'd like to provide a very simple robot design in this appendix that can be built with both the 1.0 and 2.0 versions of the robotics kit. I call it SPOT. You'll find that you can easily build SPOT in less than 5 minutes, making it a great little robot for testing your NXT-G programs.

Figure B-1 shows the parts the make up the SPOT robot. Figure B-2 shows the completed SPOT robot—complete with 1.0 and 2.0 versions of the tires—from both sides. The images on the pages in between show step-by-step how to build the robot.
