• Final Report https://docs.google.com/document/d/1U4hTdkWk3_W5jxNzboUAq03IZFFIPNzS-lzf1Dpz3Pk/edit?usp=sharing

• YOLOv3 weights，包含平台tiny、洞 https://drive.google.com/drive/folders/1iq4aOWEoC3pH7jgbg-wTGPG5zBOkf2vy?usp=sharing

State:

1. YOLO偵測平台目標物，回傳XYZ，車子朝目標逼近
2. 當行駛至70cm內，精準度增加，可以偵測深度(深度值700以內還算精準)
3. 距離平台目標50cmcm左右，切換至洞偵測模型，開始辨識洞
4. 辨識到3個洞，回傳3組XYZ
5. 手臂根據XYZ移動
