Compete

Now that you have built and tested three different gear trains for your BaseBot, you are ready for the Gear Train Tractor Pull Challenge.  In the following video, the BaseBot with a gear train is attached to two IQ Kits using a rope. When the project is started, the robot pulls the Kits forward on the Tiles.

Follow the steps in this document to complete the Gear Train Tractor Pull Challenge. Google Doc / .docx / .pdf

Once you have completed the Gear Train Tractor Pull Challenge, check in with your teacher. Ensure you have documented the results of the challenge in your engineering notebook.

Wrap Up Reflection

Now that you have tested all the gear train configurations, and competed in the Gear Train Tractor Pull Challenge, it is time to reflect on what you have learned and done in this Lesson. Start a new page in your engineering notebook to start your reflection.

Rate yourself as a novice, apprentice, or expert on each of the following concepts in your engineering notebook. Provide a brief explanation for why you gave yourself that rating for each concept:

  • How different gear combinations in a gear train create mechanical advantage
  • Choosing a gear combination for my robot that can pull the furthest
  • Problem solving with my team to add a gear train to the robot

Use this table to help you determine which category you fall under.

Expert I feel that I fully understood the concept and could teach this to someone else.
Apprentice I feel that I understood the concept enough to compete in the challenge.
Novice I feel that I did not understand the concept and do not know how to complete the challenge.

What is Next?

In this Lesson, you added a gear train to your robot and tested different gear configurations.

In the next Lesson, you will:

  • Learn about center of mass and how it impacts your robot.
  • Create an addition for your robot to change the center of mass.
  • Compete in the Tug of War challenge.

Two BaseBots face each other on either side of the center line of the Field tiles, with a rope connecting them, ready for Tug of War.
