EV3 Robot Programming Concepts

The video tutorial explains how to use a color sensor with an EV3 robot to stop at and follow a black line. It begins with an introduction to color sensors, detailing their function of emitting and detecting light. The tutorial then guides viewers through connecting the robot to EV3 using either Bluetooth or a USB cable. The main programming tasks involve coding the robot to stop when it detects a black line and to follow a black line by wiggling along it. The tutorial uses repeat until and if-then-else blocks to achieve these tasks, providing detailed instructions on setting motor power and checking light intensity.

What is the primary function of a color sensor?

• To measure distance

• To detect temperature changes

• To emit sound waves

• To emit light and detect reflected light

Which software is used to connect to the EV3 robot?

• EV3 Classroom

• Robot Studio

• Sensor Connect

• Line Follower Pro

What should you check to confirm the EV3 robot is connected?

• The robot's wheels are moving

• The icon in the top left corner is green

• The robot is making a sound

• The USB cable is plugged in

What block is used to make the robot stop at a black line?

• Wait block

• Repeat until block

• If-else block

• Repeat forever block

What should the robot do when it detects a black line?

• Turn around

• Stop moving

• Speed up

• Emit a sound

How does the robot follow a black line?

• By reversing direction

• By stopping and starting

• By wiggling left and right

• By moving in a straight line

What block is used to make the robot turn based on line detection?

• Loop block

• Wait block

• Repeat forever block

• If-then-else block

What does a reflected light intensity of 0% indicate?

• The sensor sees white

• The sensor sees red

• The sensor sees black

• The sensor is malfunctioning

What is the reflected light intensity when the sensor is on a black line?

• 50%

• Low but above 0%

• 0%

• 100%

What motor power settings make the robot turn right?

• Both motors 10%

• Right motor 20%, left motor 20%

• Right motor 15%, left motor 5%

• Right motor 5%, left motor 15%
