Robotics (Mbot2) on Quad RGB Sensor(P6)

Which feature of the quad RGB sensor helps in recognizing colors?

• Ambient light calibration function

• Magnetic detection function

• Sound recognition function

• Temperature sensing function

How many light sensors does the quad RGB sensor have?

• Four

• Two

• Six

• Eight

Why can the quad RGB sensor be used as a color detector in programming scenarios?

• Because it can detect colors

• Because it can measure temperature

• Because it can record sound

• Because it can store data

The ambient light calibration function of the quad RGB sensor improves its performance in line following tasks by:

• Reducing interference from ambient light, allowing more accurate line detection.

• Increasing interference from ambient light, making line detection harder.

• Changing the color of the sensor, making it more visible.

• Disabling the sensor’s ability to detect lines.

How many probes are equipped on the quad RGB sensor?

• Two

• Four

• Six

• Eight

What does the number in the quad RGB sensor block indicate?

• The color detected by the sensor

• The place of a quad RGB sensor among the ones connected to CyberPi

• The speed of the robot

• The temperature of the sensor

What can you select from the drop-down list box in the quad RGB sensor block?

• The line, background, or one of the colors

• The speed of the robot

• The temperature of the environment

• The sound level

Why might a robot use the quad RGB sensor to follow lines?

• To detect colors on the surface of an object

• To measure the weight of the object

• To record audio signals

• To calculate the distance to the object

Which probe is NOT present on the quad RGB sensor as shown in the diagram?

• R2

• R1

• L1

• S1

In the example provided, what happens when both L1 and R1 detect a line after uploading the program to CyberPi of mBot2?(Example 1 Lesson 1)

• mBot2 moves forward

• mBot2 stops

• mBot2 turns left

• mBot2 turns right
