POE Unit 3 Test

What is the purpose of the RobotC Debug window?

• It allows the user to Start and Stop

  their program.

• It allows the user to step through their program one line at a time.

• It must be open to use any of the other Debug windows (Sensors, Motors, etc.)

• All of the above

• None of the above

A Light Sensor is a ____ sensor

• analog

• digital

A Potentiometer is a ____ sensor.

• analog

• digital

A Quad Encoder (Shaft Encoder) is a ____ sensor.

• analog

• digital

Bumper switches and limit switches are ____ inputs.

• analog

• digital

What is the purpose of the SensorValue [sensorName] command?

• It retrieves the value of mySensor

• It sets the value of mySensor

• both of the above

• none of the above

What is the purpose of the RobotC Motors and Sensors Setup?

• It is a lookup chart that tells you where to plug in your motors and sensors and what to call them.

• It is a place where you can read all of the values of the sensors in one place.

• It is a central place to configure and name all of the motors and sensors that are connected to the Cortex.

• none of the above

What programming language is this written in?

• Standard RobotC

• RobotC Natural Language

• Pseudocode

• None of the above

What will this program cause the robot to do?

• Spin in left circles until the sonar sensor detects an object within 10 cm AND the touch sensor is pressed

• The robot will move forward if the sonar sensor detects an object within 10 cm OR if the touch sensor is pressed.

• The robot will move forward while the touch sensor is not pressed. If an object is detected within 10 cm by the sonar sensor, the robot will stop and turn left before moving again.

• The program will not run on the robot.

How does the Ultrasonic Rangefinder (SONAR sensor) measure distance?

• It sends out pulses of sound, ‘listens’ for the echo signal strength, and calculates the distance.

• It requires special equipment to be attached to the Cortex.

• It sends out pulses of sound, ‘listens’ for the echo, and the Cortex uses the amount of time it takes for the sound to bounce back to calculate the distance.

• What? That’s what that’s for?
