banner I have been a Lego League coach since 2007. This year, I wanted to document the season to give rookie coaches a resource to help them through to competition. The process can be intense, but it can also be a lot of fun for you and your team.

I hope to cover enough through my posts, but if I leave anything out, please feel free to leave a comment, or contact me.

Go Until…

Author: fllCoach | Files under Programming

In my Motor Tip #1 post, I talked about moving the robot with a duration. But because the robot can turn or move in slightly different amounts in each run, using only durations can’t ensure your robot will be where you think it is when it’s done executing its commands. In my Achieving Mission Consistency […]

Motor (and Sensor) Tip #0

Author: fllCoach | Files under Programming

As I was drafting a post about how to follow a line, it occurred to me that I have my team do something that helps to minimize confusion when programming. I was going to post it as tip #2, but realized it should have been the first tip I posted. So I’m labeling it as […]

Wider is Better

Author: fllCoach | Files under Programming

When I heard this the other night, I was reminded of the car commercials that used to say “Wider is Better.” In their case, they were talking about car stability. In the case of robots, we’re talking accuracy. Our team invited a division 2 team to come visit this week. Our guests had been together […]

Author: fllCoach | Files under Programming

In my last post, I talked about the View feature of the brick that allows you to see what the sensors attached to the brick are reading. There is one important caveat regarding the light sensor that you need to be aware of. When you use the View to see what the light sensor is […]

See What the Robot Sees

Author: fllCoach | Files under Programming

One of the really useful features of your NXT brick is the View. It allows you to see what the robot sees. This especially comes in handy with the sensors. You can see how many degrees the robot needs to move, see what the light sensor is detecting, or see the distances the ultrasonic sensor […]

I know you’ve all probably been visiting my site waiting for some programming tips. I apologize that I haven’t written many yet. I was going to write them as they occurred to me while helping my team program. I didn’t expect my team to concentrate so much on our research project early on. We’ve barely […]

Presentation Milestone

Author: fllCoach | Files under Research Project

In our last meeting, my team started practicing their presentation. This is the earliest we have finished the presentation and started practicing. But our robot has suffered for it. We’ve only just finished building the robot and have just started programming. But the nice thing is that our attention won’t be divided until our regional […]

Make the Presentation Fun

Author: fllCoach | Files under Research Project

In our last team meeting, we spent the entire hour and a half working on our presentation. I wasn’t involved with the presentation side last year as I left it to my co-coach to handle. There was a definite distinction of expertise since I was a technical guy and he enjoyed performing on stage. This […]

[Update: Due to the comments left by several experienced coaches, the tip as originally written has been revised in the comments below. Please be sure to read all the comments in their entirety to understand this tip fully.] When you are programming your robot, the motor block will be your most commonly used piece. The […]
