Treasure Hunt
Lesson 3: Claw With Sensor


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.
