聽聲辨位–盲打乒乓球(Playing Table Tennis by Sound Locating)
指導老師:張政元   組長:杜明軒   組員:莊曜隆
本次專題為聽聲辨位之延伸應用。我們把麥克風及步進馬達與樹梅派做連接,透過兩個(以上)麥克風來收取乒乓球敲擊桌面的聲音,然後將這些麥克風的訊號輸入並透過演算來判斷乒乓球敲擊桌面時的位置,最後依據演算結果來控制馬達,使桌球拍移動至適當的位置以順利回擊乒乓球。

關鍵字:聽聲辨位、樹梅派、馬達控制
We use the sound locating technique in this project. We connect the stepper motor and microphones with the Raspberry Pi. With these two or more microphones, we can record the sound which is made by the table tennis ball when it hits on the table. Then the sound recorded by the microphones will turn into signals and input to the Raspberry Pi. The Raspberry Pi will calculate the location where the ball hit on the table, and with the calculated result the Raspberry Pi will control the motor to move the paddle to the right position in order to return the ball.

Keywords: sound locating, Raspberry Pi, motor control
我們決定將壓電陶瓷晶片和鞋子做結合。
