VEX V5 Practice for Coding with Conditionals

What app is used for coding in VEX V5?

• VEXcode

• Coding 101

• VEX Coding Systems

• Coders

Why would a [If then] block be used in a project?

• To execute a set of commands only if a certain condition is true.

• To repeat a set of commands a specific number of times.

• To ask the user a question.

• To execute commands in a random order.

What is the primary function of a [Forever] block in a coding project?

• To execute a set of commands once.

• To repeat a set of commands indefinitely until the project is stopped.

• To execute commands only when a specific condition is met.

• To pause the execution of commands for a specified time.

What do the grey blocks do in the V5 Coding System?

• They tell the robot what to do.

• They are comment blocks which make the code easier to read and understand what those blocks do.

• They detect errors in your code.

• The are event blocks, which cause the next set of blocks to execute when a specific event happens.

Which of the following describes why a Repeat block would be used in a project?

• To repeat certain blocks forever.

• To save space and time for blocks that repeat more than once in a project.

• To only run a stack of blocks one time.

• To run an attached stack of blocks when the project is started.

Why is this car not starting when the bumper is pressed?

• Need to remove the wait

• Need to remove the stop

• Need a spin motor block after the set velocity block

• Need to get rid of the forever loop

What behavior will the VR Robot perform if the condition of the Left Bumper Sensor being pressed is TRUE?

• The VR Robot will continue to drive forward forever.

• The VR Robot will drive in reverse for 50 millimeters (mm) and then turn left for 90 degrees.

• The VR Robot will stop moving.

• The VR Robot will drive forward for 50 millimeters (mm) and then turn right for 90 degrees.

Commonly used with ______ Control Blocks.

• Forever

• If - Then

• If - Then - Else

• Repeat

Which of the following is the best description of what the Eye Sensor does?

• It reports the (X,Y) position of the VR Robot.

• It reports the distance between the VR Robot and the nearest solid object.

• It can be controlled to pick up and drop disks with metal cores.

• It detects if there is an object present and if so, the color of that object.

What value will the <Eye Sensor near object> Boolean block report when the Eye Sensor is close to an object that has detectable colors?

• 1. It will report TRUE.

• 1. It will report how far in millimeters (mm) or inches the Eye Sensor is from the object.

• 1. It will report the location angle of the VR Robot in degrees.

• 1. It will report FALSE.
