Default Animatronic Hand

I have developed an animatronic hand made from vinyl tubing, 5 micro servos, and mdf palm mount. Thought you all may be interested.



It was originally posted on the DIYChristmas.org site... and here is the link showing the development. This was easier than re-posting all the threads here.

Here are a couple of final demo videos if you don't want to read through the other link...

Final demo... hand standing up...

That is really neat! My first thought for an adaptation was a single index finger version that could do a "come hither" type motion.
Thanks, Mike

That is very impressive. I especially like the video of the hand with the glove on it, it looks just like a real hand! You have got to be pleased as punch with how that turned out.

Very nice! You could attach a second line to the opposite side of the fingers (and around the bobbins) to have the bobbins straighten the fingers as well as bend them. Although the glove seems to speed up the straightening. This hand would make a very convincing "Thing" prop!

All,

Thanks for the kind words. I too thought this would make a great "Thing".

The glove (skin over mechanism) does help with the believability.

The single finger "come Hither" is a great idea. And simplifies the build.

Yes, but can it play piano?

Really convincing movement in the leather glove. Is there a way to position the thumb so it's more opposable to the other fingers? That would add to the believability, although most folks would likely not notice that detail in a final prop.

Yes...that is my plan. During the development of this prototype, one thing I discovered is that the thumb needs to be elevated a bit and turned towards other fingers. In my haste to get a working prototype, I attached it the simplest way... which isn't always the best.

It did prove the concept.... now to tweak.

Also, I am developing an Articulated Model with Sensors (small model with potentiometers at key joints) where I will puppeteer the performance and record it with my 8 channel Servo Recorder Playback 60 application. That way I can get organic compound motions recorded and then played back on cue.

If interested, here is the link to my open source Servo Recorder Playback software package that runs on the Propeller Activity Board and 8 servos...

(BTW...this is the same code we used on Halstaff's Papa Voodoo and now Big Red)

And for those interested, here is my write-up on Puppeteering...an alternative approach to capturing realistic motions in your animatronic props...
