Hi All -
Need help/advice/pointers for the following project:
I have a little toy bird approx 10 inches long.
I have sliced his wing off and would like to make it rotate on command.
The wing would start at neutral position. When I trigger the “wing raise” the little bird would rotate it to almost vertical (total rotation would be approx 200 degrees)
He would hold this position until I triggered the return - at which time he would rotate his wing back to neutral position at his side.
I would like all this to happed via a WIRED controller
The most basic description of the components would be a motor that rotates to raise his arm. There would need to be some sort of limit switch to stop the rotation and reverse polarity so the next time I pushed the button the wing would rotate back to neutral - and again a limit switch to do the same thing at the end of the cycle.
And all of these items would need to be crammed into the body cavity of a little 10 inch bird.
If anyone could provide pointers to any LINK’s for compnents, etc. I would be grateful.
Better yet - If someone would be willing to build it (actually I would like 6 of them) - I would be delighted to commision them.
I had a little sketch - but message board rules prohibit my posting images on my first post.
In case anyone else ever has to build a robotic bird…
I did find some info that looks like it will help!
Something called a Sevo-Spreader which allows servos to traverse more than 60 degrees.
Looks like this will do the trick.
you never actually posted the sketch you referred to and it is difficult to picture in ones head what you are trying to accomplish in any sort of detailed mechanical way.
r/c servos out of the box travel 90 degrees and many will accept an expanded signal range to reach 180 degrees or more.
where is it not clear what you are trying to do here it is not going to be too possible for us to help without more information, ideally pictures or a sketch with descriptions.
If you expect this thing to fly using RC servos it will likely strip the gears underload and the speed is another challenge. I saw this done once on TV but there were no details on how they attached the wings to the servo.
It seems to me that this is meant to be a more lifelike decoy bird, rather than a flying model bird. Although having a flying model bird would be pretty cool too
