- Robot: EV3 - Color Front
Using a Color Sensor, program the robot only move forward when there are no obstacles!
Place a red obstacle in front of the color sensor. Program the robot to only move forward when the obstacle changes color, or moves away.
Tip: In the Virtual World, you may have to "wait for black" instead of waiting for no color.
