Robot Tutorial 1 Quiz

What is our theme this season for Robot Programming?

• Dragon eats Python

• Dragon meets Python!

• Python meets Dragon

• Dragon knows Python

What does the following statement refer to:

from pybricks.ev3devices import Motor

• Variable

• Library

• while loop

• comment

What are the statements that start with '#' are called?

• Variable

• Library

• Comment

• while loop

What is 'left_motor' called in the following statement?

left_motor = Motor(Port.B)

• comment

• variable

• loop

• library

Refer to the following lines of code:

lm = Motor(Port.B)

rm = Motor(Port.C)

dragon = DriveBase(lm, rm, wheel_diameter=70, axle_track=142.75)

dragon.straight(100)

When you run the code, the robot drives backward. True of False?

• True

• False

Refer to the following lines of code:

lm = Motor(Port.B)

rm = Motor(Port.C)

dragon = DriveBase(lm, rm, wheel_diameter=70, axle_track=142.75)

dragon.turn(55)

When you run it, the robot turns right 55 degrees? True of False?

• True

• False

Refer to the following lines of code:

lm = Motor(Port.B)

rm = Motor(Port.C)

dragon = DriveBase(lm, rm, wheel_diameter=70, axle_track=142.75)

dragon.straight(100)

When you run the code, the robot drives forward 100 meters. True or False?

• False

• True

Please refer to Robot Tutorial 1. Example 5 and 6 achieves the same purpose of driving forward and stopping at black color using color sensor.

What is the difference though?

• Both are same

• Example 5 measures color of light and example 6 measures reflection of light

Open user guide from your Visual Studio Code from EV3 icon and then describe what does the two numbers represent in the drive method shown below:

lm = Motor(Port.B)

rm = Motor(Port.C)

dragon = DriveBase(lm, rm, wheel_diameter=70, axle_track=142.75)

dragon.drive(10, 2)

What does 10 and 2 represent in the above line of code?

Consider following code:

lm = Motor(Port.B)

rm = Motor(Port.C)

dragon = DriveBase(lm, rm, wheel_diameter=70, axle_track=142.75)

What should you write if you want Robot to keep going forward without stopping?

• dragon.straight(100)

• dragon.drive(10, 0)

• dragon.straight(-100)

• dragon.drive(0, 10)
