Nice Robot, I am doing one as simple as possible.Your video have help me a lot..thanks

[@hsucody9082]

It’s great it helps.

[@allissonyonekura1342]

Can you provide the source code of the Arduino program?

[@bvedhapu]

appreciate it if you could share the bill of materials in English. thanks

[@helawn]

where did you get those orange flywheels?

[@hsucody9082]

They are tamiya mini 4WD wheels.

請問一下轉盤是用什麼跟馬達裝在一起的，因為球放下去球盤會倒

[@hsucody9082]

我的馬達轉軸是D型，我是在轉盤上下黏上塑膠片強化，不然紙作的會太軟。希望對你有幫助。

[@yucheng9515]

@@hsucody9082 那轉軸跟轉盤有什麼零件可以固定在一起呢

[@hsucody9082]

我沒有額外零件，就塑膠片挖個D型的洞，硬卡進轉軸

不好意思问下 那个转盘三个孔和两个孔是有什么差别吗？

[@hsucody9082]

同樣的轉速，兩孔的發球頻率較低，適合初學者。

[@coolzlk5809]

不好意思大大 我還有問題 那三個可調節電阻 其中一個調節頻率是調節轉盤的頻率嗎？

[@hsucody9082]

是啊。若調到轉速最快仍覺得發球不夠快，可考慮換三孔的盤。

[@coolzlk5809]

不好意思大大 我还有问题 想问下 发射乒乓球的马达 往外旋转（顺时针）或往内旋转（逆时针） 是有固定的吗？ 还是都行 都行的话 两者有什么差异 我目前是做单轮马达，再来真的很感谢大大你的视频 帮我很多，很抱歉一直问 任何不便还望见谅。

[@hsucody9082]

要順著出球方向轉（往外旋轉），不然發不了球。別客氣。

[@pianista2202]

很棒的設計，我用一個Tamiya 4 speed motor，卻卡在怎麼跟轉盤好好裝在一起，還要再好好研究研究...

[@hsucody9082]

Thanks. 我的齒輪盒轉軸是類似D型的，跟轉盤間較不會空轉。轉盤上再加一個塑膠片來增加強度，因為我轉盤是用紙板作的。

@@hsucody9082 請問您的馬達和輪胎是怎麼接在一起的呢?

[@hsucody9082]

Tamiya mini-4WD輪框軸孔是六角形的，小馬達軸徑略比它大一些些，我是直接硬塞進去

How do you spin ?

[@hsucody9082]

I cut the power of one wheel Motor. That can result in spin.

Of course it makes the ball spin and launch.
