Hi can you tell me please what the name is of these black "hinge rods" which make the flying wings? I mean the parts which are directly connected with the gear wheels :) And maybe where I can buy it? ^^' I mean the black parts in min: 2.05 Thank you! :)

y= A * sin ( angular velocity) x= cx + B * sin ( angular velocity) pitch = cos ( angular velocity) ; -)

please can u tell me how made the servos move along side with the motor at the same time?

@mulciber1212 9 жыл бұрын

MrJoshua49651 Arduino microcontroller. Keeping a tight loop which first updates speed according to a potmeter input, and actively PID control that speed. Also the encoder feedback is used to monitor where in the flap cycle the wings are, and the servo positions are adjusted to fit this cycle. Try not to make long functions or loops inside the main loop. This should keep the totalt cycle time low, and thereby the update speed on servos and motor high.... I tried using different servo libraries... It is some time ago, so i'm not sure, but maybe the library SoftwareServo, helped get the possible speed up...

Mikkel Johansen thank you!! this was really helpful but can u show me how u mounted the servo to the wing? of it to rotate like that. as I tried mounting mine but it wouldn't rotate properly l.

@mulciber1212 9 жыл бұрын

MrJoshua49651 Locked the rotating tip to one tube, and made an extended plate which locks to the servo body and moves the other tube relative to the first tube. My solutions wasn't perfect, so no need to copy that part :P Should be easier to just review your own solution :)

Mikkel Johansen I thought so even, as I was checking on the festo smart bird. thank you alot!! u have been really helpful . also u can check out my channel I make radio controlled aircraft's and quadcopters, maybe might find them interesting and subscribe please lool

Hi Sunita, It's been 4 years, so I don't remember the exact model, but it is an outrunner motor.
