PROGRAMMING A ROBOT: SOUND SENSOR SESSION 1 LESSON 7 Session 1: PROGRAMMING A ROBOT: SOUND SENSOR Objectives At the end of the lesson, the students should be able to:  Explain the use of sound sensors in robotics;  Describe how sound sensor works;  Use code blocks to program a sound sensor; and  Create a device that makes use of a sound sensor as an alarm.

Is sound important? 2. Why or why not? 3. What does sound/music gives to us? TechFactors Copyright 2022 Session 1: PROGRAMMING A ROBOT: SOUND SENSOR Explain The Me Auriga board is equipped with an onboard sound sensor. This allows students to program the robot to measure sound waves without using an external sound sensor TechFactors Copyright 2022  Session 1: PROGRAMMING A ROBOT: SOUND SENSOR Explain  The sound sensor is an input device that measures the intensity of sound waves and converts these sound waves into an electrical signal. It has a microphone that receives the sound signal. Both ultrasonic sensors and sound sensors are input devices. Still, the difference between the two is that the ultrasonic sensor measures distance of a nearby object through ultrasonic waves, and the sound sensor measures the sound loudness through the intensity of sound waves.  In the previous lessons, you have learned some of the code blocks used in programming our target robot model. To program the sound sensor of the Land Raider, we need to use the following additional code blocks. TechFactors Copyright 2022 Session 1: PROGRAMMING A ROBOT: SOUND SENSOR Explain This block can be found in debug tab, and it is used [MKS1]Please include the unit of measure used. to open a small window or screen near the robot. [j2]Done When you use the open console block, this small window appears next to the robot. It shows the value of the sound intensity in decibels (dB) that the sound sensor measures. When the small window appears next to the robot, it is still blank because you still need to program what you want the robot to show in the window. You can use the print block to instruct the robot to view the value of the sound sensor. The sound sensor block measures the sound intensity or uses its value for the conditional statement in programming. TechFactors Copyright 2022 Session 1: PROGRAMMING A ROBOT: SOUND SENSOR Explain Key programming blocks Let us create a simple program for the robot to measure the sound waves from its surroundings. Programming steps: 1. Open the Miranda Simulator using this link (Insert link here) or open the desktop app of the Miranda simulator installed on your computer. If you are using the Miranda desktop app, make sure you enter the connection code, your username, and password. 2. Click the OPEN SCENE from the cloud icon. 3. Select the scene Creators 2: L7-S1-Programming a Robot: Sound Sensor to simulate the scenario. 4. Click the Land Raider model to open the programming pane on the left side of the simulator. 5. Click the program with the Scratch icon to start building the code for the scenario. Drag the command blocks according to the image shown below. Input the values indicated in each command block. 6. Click the RUN button to start the simulation and observe the behavior of the robot. TechFactors Copyright 2022 7. If you can, create a video or screen record of the output and send it to your teacher. Session 1: PROGRAMMING A ROBOT: SOUND SENSOR Explain What are the blocks that we need? TechFactors Copyright 2022 Session 1: PROGRAMMING A ROBOT: SOUND SENSOR Explain Using the codes, the robot will detect the sound intensity at the start of the simulation. It will be able to continuously measure the changes of the intensity because of the Forever Block. The Open Console and Print Blocks allow you to view the measurement. It is good to measure the sound intensity from the surroundings before you program the robot using a conditional statement. This will allow you to choose the right value of the sound intensity for the robot. Take note that in the Miranda simulator, the work pane represents a certain location as if in the real world; thus, every time you open a scene, the specific location of the robot is always different. TechFactors Copyright 2022 Session 1: PROGRAMMING A ROBOT: SOUND SENSOR Elaborate Therefore, the sound intensity is also different. The value of decibels in Miranda scenes is not fixed, so the value of decibels that you use in your program will not be the same value you will use in your next program.

After you programmed the Land Raider to move to different directions automatically, it is time for you to program its Ultrasonic Sensor. The robot uses this sensor to avoid obstacles automatically and turns the other way when it detects objects in front of it. Your goal is to program the Land Raider to do the following outputs: When an object is closer than 15cm from the Land Raider:  Stop for 1 second  Move backward for 2 seconds  Turn left for 1 second When an object is farther than 15cm from the Land Raider: Move forward TechFactors Copyright 2022 Session 2: PROGRAMMING A ROBOT: SOUND SENSOR GUIDED ACTIVITY Guide Questions 1.
