Divide and conquer

The competition could be divided in three parts.

  1. Building a robot construction
  2. Building attachments and programming the robot for this attachments
  3. Grouping the missions of the field in as less runs as possible


This course contains a number of sections with very specific examples and tasks on how you could improve your FIRST LEGO League robot game and how to achieve more points. It is designed mostly for after season teams that would like to prepare for next year but could also work for teams that are currently working on their competition robots. FLL contains a number of missions. There are three very simple steps to accomplishing the whole field. First, you must build a robot base on which you can add the different attachments. Then you must construct the different attachments that accomplish the very specific missions and program the robot to reach these mission models. And last step you must group as many missions as you can in less runs as you can in order to save time. Here by runs I mean when you go out of base. This is the run. The missions of each year is very similar and you'll always lift something like in this current example or you carry something like with carrying this gecko or collecting or pushing. You should use sensors to make the robot position on the field and to make it more precise. Sensors like these at the bottom. And it is very important to define what is accomplishing a mission. You really accomplish a mission when the robot works 9 out of 10 times. This makes the robot stable, predictable and it is much more fun and easy to use.

You should always try to have a robot that accomplishes one mission, a second mission, a third mission but does this every time or 9 out of 10, or 9.5 out of 10, or 9.9 out of 10. But it should be stable. And that's much more important than having a robot that does all the missions but sometimes. So, always try to have a stable robot and in the following course we have a number of sections at which you can look at the FIRST LEGO League Animal Allies Competition from 2016/2017 and based on the tasks in this competition on the missions we'll look at some of the principles for solving some of the missions. Principles that you can use in some of the next competitions.
