Thank you. Finding your website is a blessing for me.I wish I have seen your video earlier so my students will have more time to make innovations of their robot for the FLL qualifying rounds. Your website is very informative. It is absolutely useful. Thank you for allowing me to view it. Currently, I have one team who will participate in the FLL. Our preliminary competition will be on January 31. We are done with the project but since we have limited background about programming and using Lego NXT mindstorm we have not completed all the challenges. Every time we test the robot, their movement change. There are times we got it then, when we repeat it it move different. So, when I saw your website and watch the video on preparing robot for a competition I understand what is happening.
