holy effin awesome!!
Can you please make some pics with better focus though (no offence, but i can hardlly make out the details in the detail shots)

What will you be mounting this on? are those ti-rips or muscles? do you control all fingers at the same time or seperate?

Edit; are they these 'mellisa' hands?

hi;

Ok updated pictures,

Yes im inspirate melissa hands, all fingers controlled with T rap

im perfectionned the position control T rap with micro screws

[Suicidal.Banana offline]

very nice man
one thing im curious about tho, i cant really tell from the mellisa hands or yours, how does it actually work? do the tirips/t-raps get pulled across a gear or something? i dont follow how it converts a little rotational motion to a pulling motion long enough to make the hand turn into a fist.

Edit:
Actually, i just found this vid, i didnt expect them to be that small, and that cool.

thank's

Yes i see your video its same project, but in the original melissa hand's its must difficult for have a fine tuning of t rap for a tRap align optimal fingers between them,

that's why I thought back to another module by setting trap trap (see photo)


For your question I do not understand (I'm frenchMy english it's not very fluent

[Suicidal.Banana offline]

Thats okay, your english is fine, and the better pics you made/the vid i linked basically answered all my questions, thx, and keep it up

Wow that's awesome!
How did you make those tiny parts? Were they machined with a CNC or something?
Good Job! that might even fit on small hobby robots like robonova!

Hi;

thank's

100% hand make, not CNC

the size its prévious for the standard biped robot (RN, Rb, Ktx or other)

If you like Robonova See my other post in Robonova section "RN2 By Kif"

It's for Sale

I saw for the first time that using melissa hand for KT-X.
It's so nice.

Please show me some movie.

I like your hand but I think many are wondering if it isn't a simple way to do it or some easy to find materials and tools to made one look like "Melissa Hand" , even if not so hard ... but hey I consider my robots very delicate even some of them are made to be very strong , like my ROBONOVA (for whom I try to make a hand like that/this).

Hope not to take as a competition, even if competition make it best I start a forum thread ABOUT MY PROJECT.

I am inspired by your skills as well...
I am gathering parts to construct my own set of hands as well...
Just wondering the gauge of aluminum you used?
Also the screws, were they 'tapped' to the holes or did you have nuts at other side?

I have another idea i might explore with my project... it wont start til january but I am getting parts together...
Do you also ad the hand controlled servos to your software project or is it some other approach?

I will set up a feed once I start my hands project...

I want to say that your melissa hand is really great!


I have 1 question(about generally the melissa hand).
How does the gripping work?
I mean, I can see the straps moving thanks to the servo, but it's kind of counter intuitive - when the strips are stretched, the hand opens, and when the strips are released the hand closes, doesn't that give a very small gripping power ? ( I mean it probably can't grip anything heavy).

Or am I wrong here? Can someone point me to a good website/movie that describes exactly how it works?

Salut Kif!

Je suis María je suis étudiante en deuxième année en L3 en Technologie Industrielle. Cette année nous avons un projet très important dans lequel on doit modifier une main en plastique d'un robot. Je voudrais bien utiliser votre solution car nous n'avons pas les moyens pour nous payer une main originale du Kondo. J'ai regardé les photos et je suis curieuse de savoir combien de pièces vous avez crée pour chaque doigt, quelles sont les applications que vous avez donné à cette main? Moi par exemple je dois soulever un verre et une bouteille en plastique pour servir le verre.
Avec mon groupe on hésite au numéro de doigts qu'il faudra mettre. Est-ce que avec votre expérience, vous pouvez me donner les renseignements nécessaires?

Merci d'avance.
Bien coordialement
María Cordero
