Infos

Program Lego® My Blocks to accurately perform navigation functions on competition mats, such as moving forward and backward quickly and precisely, turning, following walls, and following lines. This book features extensive illustrations help to bring each step and concept to life so that you can easily follow along. 

You'll start by moving your creations forward and backward accurate distances while maintaining directional accuracy. You'll then build My Blocks to turn left and right at precise angles. After that you're creations will be ready to find, follow, and otherwise use lines on the mat to improve navigation accuracy. Finally, you'll delve into using game board border walls to navigate and advanced topics, such as handoffs at speed and accelerating/decelerating to enable higher speed while maintaining navigation accuracy.

This book addresses EV3 programming in the specific context of FLL® competition. With Programming Lego® EV3 My Blocks, you will be game-ready to manage the season, prepare for competition, and compete!

What You'll Learn

• Construct and use My Blocks to improve robot performance in the FLL® Robot Game 
  
• Develop basic programming skills, including feedback, troubleshooting techniques, and unit conversion 
  
• Comment programs appropriately to note errors and consistency
  

Who This Book Is For

The book is targeted at the many FLL® coaches, mentors, and students who need help with programming the EV3, as well as the students they coach. A secondary audience is teachers who want to use the EV3 to teach programming concepts.    

Gene L. Harding is an associate professor of Electrical and Computer Engineering Technology at Purdue University, where he has taught since 2003. He has three years of industrial experience with Agilent Technologies, 28 years of combined active and reserve service in the United States Air Force, holds an MSEE from Rose-Hulman Institute of Technology, and is a licensed professional engineer. He has coached FLL teams for 5 years in a highly competitive region, and has gone to the state tournament four of those years. Recently, his team placed second in the state out of 52 teams and qualified for the international tournament at Legoland, where his team placed third in the Robot Game out of 72 teams from all over the world.
