Robotics II Final Practice

A robot's interface allows a user to...

• Interact with the robot

• Communicate with the robot

• Control the robot

• All of the above

Answer the following questions concerning interactions with a VEX V5 Robot Brain. 2. All C++ programs start with…

• VEX main ( ) { }

• run main ( ) { }

• int main ( ) { }

• task main ( ) { }

Consider the sequence: Brain.Screen.drawCircle(60,70,80) What does the number 80 represent?

• X-position

• Y-position

• Circumference

• Radius

Answer the following questions concerning interactions with a VEX V5 Robot Brain. 4. Which of the following punctuation marks represents the end of a single command?

• Semicolon

• Colon

• Comma

A (a)   is a series of commands that are completed in a specific order.

• Parameter

• Sequence

• Command

• Program Flow

A robot completes tasks in a sequence in a random order.

• True

• False

What error is shown in the sequence below? Brain.screen.setPenColor(yellow); Brain.screen.drawRectangle(15, 25, 60, 70); Brain.Screen.drawRectangle(40, 50, 65, 85);

• "PenColor" should be lower case

• There should be a period at the end of each command instead of a semicolon

• "screen" in the first command should be uppercase

• There are too many parameter values for the rectangles

Program Flow is referred to as…

• the way a robot executes a program from bottom-to-top.

• the way a robot executes a program from top-to-bottom.

• the way a robot executes a program by alphabetical order.

• the way a robot executes a program in a random order.

Consider the code below to answer the following question:
Brain.Screen.drawCircle(30,40,50, purple);
Brain.Screen.drawCircle(30,40,50,yellow);
What will be the color of the circle visible on the screen?

• Purple

• Yellow

• Both purple and yellow

• No circle will be visible

How will this code be displayed on the Robot Brain screen?

• There will be two circles of the same size and same color next to each other

• There will be two circles of the same size and same color overlapping each other

• The circles are the same size and same location. The yellow circle is not visible because the purple circle is on top of it.

• The circles are the same size and same location. The purple circle is not visible because the yellow circle is on top of it.
