Vexcode Unit

Where on the VR Robot does the Location Sensor read (X,Y) coordinates from?

• The front-center of the VR Robot.

• The back of the VR Robot.

• The left side of the VR Robot.

• The right side of the VR Robot.

In what units does the (Position of Robot) block report the X or Y coordinates position of the VR Robot?

• Degrees

• Seconds

• Millimeters (mm) or inches

• Centimeters (cm)

Which of the following is NOT a common use of the Location Sensor?

• To detect the color of an object near the sensor.

• To navigate the (X,Y) coordinates of any Playground.

• To move the VR Robot to a known location.

• To determine the current angle of the VR Robot.

In this project, the VR Robot will drive along the Y-axis until the value of the Location Sensor is greater than what value?

• -400

• -900

• -250

• -650

How does the X coordinate value change as the VR Robot moves forward in this project on the Numbered Grid Map Playground?

• It decreases as the VR Robot drives forward.

• It increases as the VR Robot drives forward.

• It remains -800 millimeters (mm) as the VR Robot drives forward.

• It remains -100 millimeters (mm) as the VR Robot drives forward.

This project is intended to drive to number '6' on the Number Grid Map Playground but does not work. Number '6' has the coordinates X: 50 and Y: -900. What is the error?

• The <Less than> block should be set to -900 not 50.

• This project should use a <Greater than> block instead of a <Less than> block and be set to -900.

• The <Less than> block should be set to -900 not 50.

• This project should use a <Greater than> block instead of a <Less than> block and keep the same parameters.

• (Position of Robot) block

• <Pressing bumper> block

What are the approximate coordinates for the number '13' on the Number Grid Map Playground?

The coordinate location of the number '7' on the Number Grid Map Playground is X: 300 millimeters (mm) and Y: -900 millimeters (mm). What is the correct sequence of commands to code the VR Robot to drive from the number '1' to number '7?'

• Turn right for 90 degrees, Drive forward, Wait until the Y position is greater than 300 millimeters (mm), Stop driving.

• Turn right for 90 degrees, Drive forward, Wait until the X position is greater than -300 millimeters (mm), Stop driving.

• Turn right for 90 degrees, Drive forward, Wait until the Y position is greater than 300 millimeters (mm), Stop driving.

• Turn right for 90 degrees, Drive forward, Wait until the X position is greater than 300 millimeters (mm), Stop driving.

This project is intended to drive to number '61' on the Number Grid Map Playground but does not work. Number '61' has the coordinates X: -900 and Y: 300. What is the error?

• The <Less than> block should be set to -300.

• This project should use a <Greater than> block instead of a <Less than> block and be set to -900.

• This project should use a <Greater than> block instead of a <Less than> block and keep the same parameters.

• The <Less than> block should be set to -900 instead of 300.
