Introduction

In this Lesson you will learn about the Optical Sensor, and how it can be used with [If then] and [Repeat] blocks in a project to make your Simple Clawbot collect a cube based on its color. Then you will apply what you have learned to compete in the Treasure Mover Challenge, where your robot will need to collect only the red Treasure Cube. View the animation below for an example of the how your Simple Clawbot could move to detect the color of the cubes and move only the red cube to complete the challenge.
