Hi bro, in tower pro mg90s and tower pro mg955 , in this 2 servos which is better or can u suggest me some better option

And another question in sine wave and square wave how can we differentiate in code ,plz give me the suggestion my model is ready but not going high ,I will change servo but what change I should make in code plz reply

ありがとうございます。とても興味深いです。駆動サーボの能力（動作スピードとトルク力）で変わるのではないでしょうか？サーボにによる羽ばたきでは、羽ばたき回数が上がるとサーボのスピードが追いつかなくなり、羽ばたきの振幅が減ってしまい、推力が落ちることを経験しています。矩形とは言っても実際の羽ばたき回数多いときの羽ばたきの動きは正弦波になっていると思います。羽ばたき振幅の頂点から最下位までの移動の間にプログラムが働かない方が羽ばたきの時間が短くなり、その分推力が上がるように思います。

コメント有難うございます。私は当初、正弦波（近似）制御のほうが、推力がUPするのではないかと思って 慣れないプログラムに四苦八苦して、正弦波（近似）の出力プログラク作りテストしましたが、 意に反して結果的にあまりよくありませんでした。今回のテストでは、基本的な条件は同じにして サーボへの出力信号のみ制御方法を変えて比較してみました。その他の条件がいろいろ変化した場合 結果が、変わるかも知れません。

@@y.takemura8488 Hi sir Frequency changes controls the angle,the servo motor make Since sine wave have slow transition can't give fast respons to the input But square wave have fast transition unlike above So square wave is better, I think

Originally, servo motors were not designed for harsh operations such as flapping drives. We use it on the assumption that it will be damaged.

The square wave puts a heavy load on the servo, generates more heat, and may shorten the service life.

Bro can u tell me how to make the servo system moving up and down

Raise or lower the center position angle of the flapping amplitude, Up and down. When the center position is on the descending side, the head is effectively raised, and movement equivalent to that for raising control occurs.

If the servo uses Tower Pro SG90, both power and speed are NG. If you do not use a high-class servo with strong power and speed, torque and speed will be insufficient. I haven't published the arduino code.

The film used on the surface is Power Lip T6016 (white). There should be other lighter materials, please look for them.

yes spanish
