Frequently Asked Questions - LEGO Robotics Projects

Your FIRST LEGO League Robotics project is an engineering project that can be entered in the Intel Northwest Science Expo! More than likely, you have used engineering goals and the development process to make your robot complete the missions for the FLL Challenge for this year.

Goals of Engineering (From the Student Handbook for Pre-college Science & Engineering Projects, 2005-2006 Edition):

An engineering project should state the engineering goals, the development process, and the evaluation of improvements. Engineering projects may include the following steps:

  1. Define a need.
  2. Develop design criteria.
  3. Search literature to see what has already been done.
  4. Prepare preliminary designs.
  5. Build and test a prototype.
  6. Retest and redesign as necessary.

 

Figuring out how your project follows the engineering goals is as easy as answering a few questions. You may not need to answer all of the questions, and you may find other questions that need to be answered, but these are a guideline.

  • What is the need?
    • What does your robot need to accomplish?
    • What are the limitations (size, weight, power, building materials)?
  • What are your design criteria? How should your robot accomplish these things?
    • How is it accomplished by programming?
    • How is it accomplished by building a particular part of your robot?
    • How did this particular mission solution fit into your overall design for the robot?
  • What has already been done? Did you do any literature searching?
    • Did you base your robot on examples found elsewhere?
    • What examples are these?
    • How did you improve on them?
  • Did you test, evaluate, and redesign your robot?
    • When you made your robot, what early designs did you try?
    • What worked and didn’t work?
    • Why did you change the design?
    • How did you change the design?
    • Did the design changes work?
    • How did all your design changes interact to make your final robot?

 

Prototype: A working model used to demonstrate and test some aspect of the design or the design as a whole. A prototype is produced before the final version. So your early designs of your LEGO robot are all considered prototypes, while your competition design is your final version.

Your project can focus on your robot’s physical characteristics, or on its programming, or on both. You can choose to focus on solving one or two particular missions, or you can focus on how your robot solved all the missions in the challenge. One of the things you need to keep in mind, however, is that the judges will have a limited amount of time to see what you’ve done, so you may want to concentrate your science fair project and display to one part of your robot that really shows the effort and innovation of your team!

You should enter your project in the Engineering category. For middle school team size does not matter. For high school students, ISEF caps team size at three.

If any of your team is in the 9th grade or higher, you must enter your project in the High School division, otherwise your team competes in the Middle School division.

Since the project is a group effort, everyone on the team must agree that it can be entered in the science fair. At least two of your team must be willing to come to the Intel NWSE to compete in the judge interviews. Quite a bit of the judging criteria deals with teamwork, so the more members of your team who participate in judging, the better your scores will be.
