    Study Notes

    Robot Programming: Sound Sensor

    • Session 1 Objectives: Students should be able to explain the use of sound sensors in robotics, describe how a sound sensor works, use code blocks to program a sound sensor, and create a device that uses a sound sensor as an alarm.

    • Engage Activity: Identify robot sensors (G, A, N, C, E, F, E).

    • Explore Activity Questions:

      • Is sound important?
      • Why or why not?
      • What does sound/music give to us?

    • Explain (Session 1):

      • The Me Auriga board has a built-in sound sensor, allowing sound wave measurement without external sensors.
      • The sound sensor is an input device that converts sound waves into electrical signals using a microphone.
      • It measures the intensity of sound waves, unlike ultrasonic sensors that measure distance.
      • Key programming blocks for the Land Raider sound sensor are needed.

    • Explain (Session 1): Programming Blocks:

      • Open Console: Opens a display window to show sound intensity (in decibels).
      • Print: Displays the sound sensor's value (intensity) in the debug window.
      • Sound Sensor On-Board Loudness: Measures sound loudness using the built-in sensor.
      • When Starts Up: Starts a code block when the program first starts.
      • Forever: Loops a code block repeatedly during the entire program.

    • Explain (Session 1): Programming Steps:

      • Open the Miranda Simulator
      • Select the scene (Creators 2: L7-S1-Programming a Robot: Sound Sensor).
      • Drag and connect command blocks.
      • Enter the appropriate values in each block.
      • Click Run to start the simulation.
      • Record the output and submit.

    • Elaborate (Session 1):

      • Sound intensity measurements in the Miranda simulator are specific to the particular scene; they will vary between simulations.

    • Evaluate (Session 1, Part A): True/False Questions:

      • Sound sensors detect sound waves through microphones. (True)
      • Sound sensors convert sound waves to electrical signals. (True)
      • The Forever Block measures sound intensity changes. (False)
      • External sound sensors are needed to program the Land Raider. (False)

    • Evaluate (Session 1, Part B): Correct Block Combinations:

      • For measuring sound intensity only at the start of the simulation, use "When starts up," "Open console," and "Print sound sensor on-board loudness". (B)
      • For measuring sound intensity while a key is pressed, consider the block combination "When a key is pressed", "Open console", and "Print sound sensor on-board loudness. (B)

    • Evaluate (Session 1, Part C): Correct Blocks for Sound Intensity: The block combination that shows the sound wave intensity is "When o key is pressed", "Open console", and "Print sound sensor on-board loudness". (A)

    • Evaluate (Session 1, Part D): Robot Output Actions: The correct answer is "The robot turns left and shows the value of sound intensity at the same time." (B)

    • Evaluate (Part E): Print Statement: The Print "sound sensor on-board loudness" block is the one to print the sound intensity value.

    Robot Programming: Sound Sensor (Session 2)

    • Guided Activity (Session 2):

      • The robot programs an ultrasonic sensor to automatically move and react on obstacles it detects when their distance is less than 15cm away from the sensor.
      • When it detects an obstacle (closer than 15 cm), it stops for one second and moves backward for two seconds, then turns left for one second.
      • If the obstacle is further away (farther than 15cm), it moves forward.

    • Guided Activity (Session 2, Part B): Programming steps for the Miranda Simulator.

      • Open the Miranda application and enter the correct connection code, username, and password.
      • Use the cloud icon to open the necessary scene.
      • Select the scene: Creators 2: L7-S1-Programming a Robot: Sound Sensor.

    • Independent Activity (Session 2):

      • Emergency robots use sound sensors to detect noise, helping them locate and rescue individuals.
      • The objective is to program a robot that moves forward if it detects sound waves higher than 25 decibels.
      • Key questions to answer:
        • What blocks are needed?
        • How to use these blocks to detect sound intensity?
        • What is the lowest and highest sound intensity this sensor can detect?

    • Independent Activity (Session 2, part B): Questions to answer

      • What operator to use for comparing decibel intensity?
      • What would happen if the robot only had the Move Forward block outside the Forever Block?
      • Can the Less Than Block be used for conditional statements?
      • What happens if the calculated sound intensity is below the set value?
      • What happens if the decibel value is set to its maximum range allowed?

    • Independent Activity (Session 2, part C): Rubric

      • Criteria for grading robot program using the Miranda Simulator.
      • Focus areas: Understanding of variables, program efficiency, and ability to follow instructions. A rubric is available to score.
