Learn
Before you can compete in the Eye Spy Treasure Challenge, you first need to learn about the Optical Sensor, and how you can code your robot to use sensor feedback to complete a task, such as finding specific colors of Buckyballs. You will also learn how to use additional Control blocks like [If then] and [Repeat] to have your robot make decisions.
Catapult Design
The Optical Sensor has three main functions: to detect objects and their proximity, detect the color of an object, and detect ambient light or the light reflecting off of an object.
