Practice
In the last section, you learned how the Optical Sensor works and how you can use data from this sensor in your code to have your robot make decisions. Now, you are going to apply what you have learned to code your Simple Clawbot with an Optical Sensor to complete the Eye Spy Treasure activity.
In this activity, your robot will drive to two different IQ Cubes and use the Optical Sensor to detect the color of each cube. If the cube is red, your robot should collect it with the claw and move it to the Home Zone.
Watch the video below to see how you can apply what you have learned to complete the Eye Spy Treasure practice activity.
Now it's your turn to complete the Eye Spy Treasure practice activity!
In this animation, the robot moves autonomously to check each cube with the Optical Sensor, but only pick up the red cube to collect it in the Home Zone. Watch this animation to see one possible path your robot could take to complete the Eye Spy Treasure practice activity.
Follow the steps in this document to complete this activity.
As you complete the Eye Spy Treasure practice activity, document your findings in your engineering notebook.
- Think about the distances that the robot will need to travel to drive to each of the cubes.
- Think about what the robot will need to do when it detects a red cube.

Prepare for the Challenge Activity
In Compete (on the next page), you will code your robot to autonomously check cubes and collect only the red cube in the Home Zone. Learn how to compete in the Treasure Mover Challenge, check your understanding, then practice for the challenge.
The goal of this challenge is to have your robot autonomously drive to check the cubes on the Field, and collect the red cube to the Home Zone in the fastest time.
Watch this animation to see an example of how your robot could move in a successful run of the challenge.
This is just one possible path your robot could take to complete the Treasure Mover Challenge.
