• 
• 
• 

What condition will the bumper switch report when it is pressed?

• a. TRUE

• b. FALSE

• c. It will not report a condition.

Which of the following best describes the Distance Sensor?

• a. It is a switch that can return a value of pressed or not pressed

• b. It is a sensor that uses a pulse of laser light to determined the distance from the front of the sensor to an object in front of it

• c. It is a sensor that can report the color of an object in front of it

• d. It is a sensor that can report the robot’s rotation on an axis

Which of the following is the correct definition of a non-waiting block?

• a. Non-waiting blocks have the stack continue, even if the block’s behavior is not yet complete.

• b. Non-waiting blocks pause the rest of the stack until that block’s behavior is completed

• c. Non-waiting blocks cause the entire stack to restart

• d. Non-waiting blocks cause the stack to skip ahead to the last block

Which of the following is a benefit of using a [Wait until] block in your project?

• a. The robot and obstacle’s position must stay the same in order for the project to work as intended

• b. The robot cannot use sensor data to detect an obstacle

• c. The obstacle location or position of the robot can change, and the same desired action will occur

What will the robot do when this project is run?

• a. Drive forward 200mm and turn left 90 degrees

• b. Drive forward until the Bumper Switch is pressed, then stop driving

• c. Turn left 180 degrees

• d. Wait until the Bumper Switch is pressed, then start driving in reverse

Which of the following is NOT a possible use of the Distance Sensor?

• a. To detect if a robot is near an object

• b. To report how far an object is from the sensor

• c. To report the relative size of an object

• d. To report if it is pressed or not pressed

What will the robot do when this project is run?

• a. The robot will drive forward for 200mm, and then turn right for 90 degrees

• b. The robot will drive forward and when the distance sensor detects an object, it will turn right for 45 degrees

• c. The robot will drive forward and when the distance sensor detects an object is less than 50mm away, it will turn right for 90 degrees

• d. The robot will drive forward and when the distance sensor detects an object, it will stop driving.

Which of the following is TRUE of how the Distance Sensor works?

• a. The sensor measures the time it takes for the pulse of light to travel to and from an object, and does a calculation to determine the distance

• b. The sensor calculates how far the robot travels, and reports that data

• c. The sensor can report the color of an object on the Brain screen
