I intend to make something like the original, but with some HITEC servos (because I made it for my ROBONOVA).I'll post soon some more photos but first I'll finish the prototype hand and fit it on a servo to see how it works:

Yes BrianG those are spring loaded watch type telescopes (watch spring bar - it's the exact name) and billyzelsnack I bought them from an usual Watch Repair Shop, very cheap found on eBay.

I'll post some short movie clips with some very easy and handy techniques about how to cut , bend and polish those pieces and how to put them together. Keep it close!

I like this style! Finally I think I can give the Melissa hands a try. I'd also like to know where you got the telescopes.

Hi,
I'm a robotic enthusiast like all the people in this forum.
Ever since I saw the "Melissa hand" type I tried to made
one every one could do it, without very special cutting tools
or hard to find parts.

I will post some pictures that will speak from themselves and I'll
respond to any questions you'll put here on the forum about them.
Other pictures I can take on request or you can look at my FLICKR
profile.

I only want to add that the materials used are:
- Aluminum board 0.66mm thick (with ~1.5mm diameter holes)
- Watch type telescopes (6mm wide)
- Plastic cable ties (~2.5mm wide)

and some tools:

- Hand grinder (engraver) ; nothing special only something to cut and polish the aluminum which is softer
- A pair of pliers to bend the aluminum board (very easy to bed BECAUSE OF THE tiny HOLES and ALUMINUM material softness)

For the rest I let your curiosity to discover anything I maybe forgot to mention. Enjoy:
