Speedy Delivery Quiz

In this project, what will the robot do?

• Open the claw, wait 1 second, close the claw, and then reopen the claw again.
• Open the claw, wait 1 second, close the claw and then lift the arm.
• Lift the arm, wait 1 second, lower the arm back to a position below where it started, and then open the claw.
• Lift the arm, wait 1 second, lower the arm and then open the claw.

Which of these is the correct definition of a [Spin to position] block?

• A block that spins the motor to reach a specific position measured in degrees based on its full range of motion
• A block that spins the motor in a specific direction for a specific distance
• A block that resets the motor’s position
• A block that sets a timeout for the motor

The robot was supposed to drive forward and grab an object. What is the biggest error in this project?

• The claw should open before the robot drives forward.
• The Claw Motor needs to be programmed to spin for distances greater than 180 degrees.
• The Claw Motor should only be programmed using [Spin to position] blocks.
• The project makes the robot first drive in reverse.

What will this project have the robot do?

• The claw will open 200 degrees in 3 seconds and then the robot will drive forward.
• The arm will lift for 200 degrees within 3 seconds and then the robot will drive forward.
• The robot will open the claw 200 degrees and then drive forward for 15 inches or as far as it can within 3 seconds.
• The robot will drive forward after the claw has opened 200 degrees or reached the timeout limit of 3 seconds.

A programmer can use a [Set motor timeout] block to make sure that the project does not get stuck if a motor's motion block cannot complete its movement.

• True
• False

Which of these lines of pseudocode would be best for programming a robot to grasp and transport an object to a new location?

• Find and pick up an object.
• Open the claw, drive forward 15mm, raise the arm 360 degrees, drive in reverse 15mm, lower the arm 360 degrees, and close the claw.
• Pick up the object and move it 15mm.
• Open the claw 75 degrees, drive forward 10mm, close the claw 60 degrees, raise the arm 315 degrees, and open the claw 60 degrees.

Look at this image of the VEX IQ Brain’s Device Info screen. What is the current position of the Arm Motor?

• 0.75 degrees
• 271 turns
• 271 degrees
• 0 degrees
