AI 怎麼分辨狗和貓？

4寫程式並執行

哪個積木負責什麼？

• 直流馬達 1狗的尾巴
• 直流馬達 2貓的尾巴
• LED積木貓的表情
• 聲音積木狗的叫聲

把預測結果連到動作

狗

• 播放音效
• 讓馬達 1 向左／向右轉
• 停止馬達 1

貓

• 在 LED 上顯示愛心
• 讓馬達 2 向左／向右轉
• 停止馬達 2；清除 LED

背景

• 停止馬達 1
• 停止馬達 2
• 清除 LED 畫面

先把命名積木和訓練積木各點一下。之後每當 AI 認出一個類別，「when received label」積木就會自動執行。

name label [1 v] as [狗] :: #52b98a

train label [1 v] :: #52b98a

when received label: [1 v] :: hat #52b98a
播放音符 [效果小 v] :: sound
旋转直流电机块1 (1) [向左旋转 v] 秒 :: motion
等待 (1) 秒 :: control
旋转直流电机块1 (1) [向右旋转 v] 秒 :: motion
等待 (1) 秒 :: control
关闭直流电机块1 :: motion

name label [2 v] as [貓] :: #52b98a

train label [2 v] :: #52b98a

when received label: [2 v] :: hat #52b98a
显示 [♥ v] :: looks
旋转直流电机块2 (1) [向左旋转 v] 秒 :: motion
等待 (1) 秒 :: control
旋转直流电机块2 (1) [向右旋转 v] 秒 :: motion
等待 (1) 秒 :: control
关闭直流电机块2 :: motion
清空畫面 :: looks

name label [3 v] as [背景] :: #52b98a

train label [3 v] :: #52b98a

when received label: [3 v] :: hat #52b98a
关闭直流电机块1 :: motion
关闭直流电机块2 :: motion
清空畫面 :: looks

測試前，每個類別先訓練 15 張以上不同的範例。檢查標籤的切換、等待時間和馬達方向。

Try it out

Turn on the camera and show a dog photo, then a cat photo, to the camera. You can print the photos or show them on another device's screen. Check that the robot's movement changes with the label the AI recognises.

1. Show a dog photoA sound effect plays and the dog's tail (motor 1) wags left and right.
2. Show a cat photoA heart appears on the cat's face (LED) and the cat's tail (motor 2) wags.
3. Take the photo awayWith no dog or cat (background), the motors stop and the LED display clears.

If the movement doesn't change reliably, collect more example photos for that class and train again. Try a few more times at different distances and lighting.
