Changing Velocity Build Quiz

You can program your robot to move without using a block that sets velocity.

• True
• False

When would it be appropriate to use a block that sets velocity in your project?

• To change the robot's direction from driving forward to driving in reverse.
• To drive the robot forward a certain number of inches.
• To allow the robot to have more control when carefully completing a task such as maneuvering though an obstacle course or maze.
• To stop all of the motors from moving.

There is only one block that sets velocity for both driving and turning.

• True
• False

In this project, how far does the robot move at 10% velocity?

• 5 inches
• 3 inches
• 12 inches
• 4 inches

Erin programmed her robot to drive forward 12 inches at 50% velocity. If Erin wants to move the same 12 inches in a faster amount of time, how should she change the velocity if at all?

• Increase the velocity so it is more than 50%
• Keep the velocity the same at 50%.
• Decrease teh velocity so it is less than 50%.

Bobby wrote this example program. He noticed that when he runs the project, the robot starts to move out of control when it begins to turn. What should Bobby do in order to have his robot make more controlled movements when it begins to turn?

• Decrease the set drive velocity.
• Change the direction of the turn from right to left.
• Increase the set drive velocity

• Decrease the set turn velocity

Which of the following best describes how the robot will behave based on this project?

• The robot will spin in a circle at 25% velocity.
• The robot will turn around at 25% velocity, drive for 5 inches at 75% velocity, then turn around again at 25% velocity.
• The robot will drive forward for 5 inches at 25% velocity, then turn around at 25% velocity.
• The robot will turn around at 75% velocity, drive for 5 inches at 25% velocity, then turn around again at 75% velocity.
