Ornithopter サーボ駆動蝶型羽ばたき機 SFOBlueMorph122-2small 27g : 21th Flight with 4A DC converter in Wind 羽ばたきを強くするため、DC converter（出力3A）を4Aに変更。 羽ばたきが少し強くなったかも。 　 27ｇ+Lipo150mAh4g=Total 30.5g Natural butterfly wing structure (front wings overlapping rear wings, SFOBlueMorph122-2) provides more thrust and allows for more dynamic flight than a wing structure with separate front and rear wings (SFOButterfly135, Cabbage). 1) The size of the wings was reduced to increase the amplitude of the flapping. This resulted in the overall size being made smaller. 2) The rear wings were raised slightly higher to stabilize the pitch axis (reflex surface), but this was done symmetrically using the entire rear wings. --This also reduces weight. It is closer to the shape of a real butterfly. 3) Left and right control was performed using the difference in amplitude between the left and right wings. This is closer to the control of a real butterfly. 4) It was found that tilting the left and right wings with the Aileron allowed it to turn left and right. However, this was the opposite movement to the SFO with a tail. This was thought to be because the center of gravity moved left and right. 自然の蝶の羽の構造（前の羽が後ろの羽の上に重なる　SFOBlueMorph122-2）のほうが、前羽と後羽が分離された羽の構造（SFOButterfly135　Cabbage）より、推力が大きく、ダイナミックな飛行ができる １）羽ばたきの振幅を増やすため、羽の大きさを小さくした。そのため全体を小さくした。 2）ピッチ軸の安定のため後ろの翼を少し上にあげていたが（reflex surface）、これを左右対称に後ろの翼全体を使って行った。--軽量化にもなる。本物の蝶の形に近くなる。 3）左右への操縦は左右の羽の振幅の差を使って行った。本物の蝶のControlに近くなる。 4）Aileronで左右の羽を傾けることで、左右へのターンができることが分かった。ただし、尾があるタイプのSFOとは反対の動きとなった。重心位置が左右に動くためと思われた。 Butterfly type ServoFlapOrnithopter Width 670mm Length 255mm Weight 27g Lipo 150mAh1cell Total weight 30g 2.4GHz PPM Rx Arduino pro mini Blue arrow AF D43S-6.0-MG Digital Servo 1cell Lipo convert to 6V -------------------------------- I made new Servo flap system by Arduino with PPM RX New Servo Flap System by K.Kakuta 1 Bilateral Servo Flap between Max high point and Max low point - change max flap point (throttle stick) and change Flapping frequency(5chLS) 2 Change center of Flapping angle Horizontal (Ch1 aileron stick) and Vertical (Ch2 elevator stick) 3 Change flapping amplitude on each Servo (Ch4 rudder stick) Increase flap amplitude of one servo and decrease flap amplitude of another servo Setting : Set elevator and rudder and aileron stick Center-- 1500microsecond Set 5Ch at Left Slider or other switch Set throttle stick and 5CH at low max --1000 microsecond   PPM Receiver-- RX PPM signal input to D2 pin Servo right --D5 pin Servo left --D6 pin Ground -GND pin 6V -RAW pin( 6V from stepup DC converter) Need new well act Lipo battry Arduino code Version2 is here: https://github.com/KazuKaku/2ServoFlapOrnithopter 　　　　　　　　　　　　　　　　　　　　　　　　http://kakutaclinic.life.coocan.jp/SFOsys2S.html Ornithopter,羽ばたき機,鳥,ロボットバード,RC,Servo,Arduino,蝶、butterfly , BlueMorpho
