Treasure Hunt
Lesson 3: Claw With Sensor

Compete

Now that you have practiced using the Optical Sensor to detect and collect a red Buckyball, you are ready to compete in the Treasure Mover Challenge!

The goal of this timed trial challenge is to have your robot autonomously drive to check all the Buckyballs on the Field, and collect only the red Buckyball to the Home Zone in the fastest time. Watch the animation below to see an example of how your robot could move in a successful run of the challenge.

Follow the steps in this document to complete the Treasure Mover Challenge. Google / .docx / .pdf

Once you have completed the Treasure Mover 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 used the Optical Sensor to detect and collect the red Buckyball, and competed in the Treasure Hunt 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 to use the Optical Sensor to detect a red Buckyball
  • How to create a project in VEXcode EXP to drive and pick up the red Treasure Buckyball and move it to the Home Zone 
  • Iterate with my team to detect and move the red Buckyball to the Home Zone in a faster time

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 the Optical Sensor to your robot, and coded it to detect a red Buckyball. Now it is time to compete in the Treasure Hunt competition!

In the next Lesson, you will

  • Go over the rules of the competition.
  • Develop a game strategy.
  • Compete in the Treasure Hunt competition!
