Which of the following is the correct order of steps to configure a Drivetrain in VEXcode EXP?

• Select the [Drive] block, Select Help, Drag the [Drive] block into your project

• Open the Devices Window, Select ‘Add a Device’, Select ‘2 Motor Drivetrain’, Select the ports on the Brain that your motors are plugged into, Select ‘Done’

• Open the File menu, Select ‘Open Examples’, and select a project

• Open the Devices Window, Select ‘Add a Device’, Select ‘Bumper Switch’, Select ‘Done’

Which part of the [Drive for] block do you use to change the distance the robot will travel?

• 1

• 2

• 3

• 4

Which of the following best describes what the robot will do when this project is run?

• The robot will drive forward for 200mm then turn right 90 degrees, four times, to drive in a square.

• The robot will drive forward 200mm, then turn right 180, then drive back to its starting position.

• The robot will open the ClawMotor 90 degrees, then close it 90 degrees, four times.

• The robot will turn left 90 degrees four times, to rotate in a circle.

The ____________ block is a non-waiting block that is typically used with sensors, and will make your robot drive forever.

• Turn for

• Spin for

• Drive

• Drive for

This project is intended to drive the robot forward for 300mm, then turn right for 180 degrees, and drive forward for 300mm to return to its original location, however it is not working as intended. Which of the following best describes the problem in the project?

• The Turn for block should be replaced with a Turn block

• The parameter of the Turn for block should be set to 90 degrees

• The second Drive block should be set to reverse

• Both Drive blocks should be replaced with Drive for blocks with the parameters set to ‘forward’ and ‘300 mm’
