What is the primary function of the Distance Sensor in a LEGO SPIKE Prime forklift?

• Detecting colors on objects

• Measuring the tilt angle of the forklift

• Detecting obstacles and measuring distances

• Controlling motor speed

How can you program the Distance Sensor to stop the forklift when an object is detected within 10 cm?

• Use a loop that constantly checks the sensor value and stops the motor if the distance is ≤ 10 cm

• Use a Color Sensor to detect objects instead of the Distance Sensor

• Manually stop the forklift before it reaches the object

• The Distance Sensor cannot detect objects in SPIKE Prime

What type of values does the Color Sensor return in LEGO SPIKE Prime?

• Only numerical distance values

• Color names (like "Red," "Blue," etc.) and reflected light intensity

• Motor rotation speed

• GPS coordinates

If you want your forklift to only pick up red objects, how should you program the Color Sensor?

• Use an "If" condition to check if the detected color is red before activating the lift motor

• Use the Distance Sensor instead

• Make the forklift move in random directions until it finds an object

• The Color Sensor cannot differentiate between colors

How does the Distance Sensor work in a LEGO SPIKE Prime Forklift?

• It uses ultrasonic waves to measure distance

• It uses a laser beam to measure distance

• It detects the weight of objects

• It only works when the forklift is moving backward
