AI如何区分狗和猫？

4编程并运行

哪个积木负责什么？

• 直流电机1狗尾巴
• 直流电机2猫尾巴
• LED积木猫的表情
• 声音积木狗的叫声

把预测结果和动作连接起来

狗

• 发出音效
• 电机1向左 / 向右转
• 停止电机1

猫

• LED显示爱心
• 电机2向左 / 向右转
• 停止电机2；清空LED

背景

• 停止电机1
• 停止电机2
• 清空LED屏幕

先把“将标签命名为”积木和“培训标签”积木各点一次。之后，每当AI认出一个类别，“收到标签时”积木就会自动运行。

将标签[1 v]命名为[狗] :: #52b98a

培训标签[1 v] :: #52b98a

收到标签[1 v]时 :: 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

将标签[2 v]命名为[猫] :: #52b98a

培训标签[2 v] :: #52b98a

收到标签[2 v]时 :: 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
清空屏幕 :: looks

将标签[3 v]命名为[背景] :: #52b98a

培训标签[3 v] :: #52b98a

收到标签[3 v]时 :: hat #52b98a
关闭直流电机块1 :: motion
关闭直流电机块2 :: motion
清空屏幕 :: looks

测试前，每个类别都要训练15个以上不同的样本。检查标签的切换、时间设置和电机方向是否正确。

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.
