最後,在零件樹按滑鼠右鍵,選擇Ground,設定底板為Ground後,拖動底板就不會動,所有的joint都以底板為基礎

組裝完成後,請確認所有零件已經固定,不會移動,可輕輕拖動零件確認

Step 4: 安裝sensor、電池

為底盤開孔

Step 5: 製作前擋板和鏟

來到這一步,機械人已基本完成,有基本的功能,接下來最後一步要製作前方的檔板和鏟,第一個步驟是要先製作用以安裝前方檔板的支架。

製作3D打印支架

為前擋板開孔

恭喜,設計應該已經大致完成了。為了確保設計沒有錯誤或會相撞的問題:
  • 拖動每個零件,以確定它們正確地組裝在一起
  • 使用Fusion 360的interference指令,可以自動計算模型是否有干擾(即相撞)的問題

Step 6: 微調功課

image-20230612112227922image-20230612112346334

 

這個模型存在以下問題:

  1. 30度的擋板需要增長,以便更好地發揮鏟的效果。此外,需要添加一層薄金屬或膠片令其更貼地

  2. 對地的邊緣傳感器(Line Sensor)需要更靠前,以便更早地檢測到前方是否為場外,並停車

  3. 三角支架需要移後,或將小車的長度縮減,如果不移後,30度的鏟加長後,整車就會超過200mm,會犯規不能作賽

  4. 對敵紅外線傳感器需要往前移

    • 這樣前擋板就不需要開那麼大的槽

    • 而且能紅外線傳感器的檢測距離有限,越前越能提早感測到敵人
