Second book in my Student's Guide series. This book guides you through building a R3D4 robot, outlining how determine what your robot will do and steps in creating a program for navigation. It covers components you will use in building the robot, including motors, sensors, batteries and other items. Programs are provided for robot navigation, the MP3 Player Shield and 7 color LEDs. Building robots can be fun and educational, plus provide skills that you might need in the robotics industry. In the Algorithm chapter you can lay out the steps used in your code for the robot to solve the problem. You can use a simple algorithm, or one with pseudo-code. A flowchart is explained as a way to solve logic errors in your code. The Components chapter will help you to identify the components you will need in building a robot similar to my R3D4 robot.
