Robotic Hand controlled by Gesture with Arduino + Leap Motion http://www.instructables.com/id/Robotic-Hand-controlled-by-Gesture-wi...

1 of 6 5/2/2014 6:21 PM

Hello everyone,

As promised I have made a full step by step instruction for my university final

project!

First of all: sorry for my bad english! If something isn't clear, please leave a

comment.

The hand is controlled by Leap Motion + Arduino Uno (Standard Firmata,

Nodejs & Johnny Five) + Servo Motors and the hand itself was made with

Polymorph. It can recognize each finger and it can move them separately with

very good precision and sensibility! This prototype can be controlled remotly too

via a normal web server using ajax/json requests. Let me know what you think

about it and maybe I will publish a complete tutorial when I will have more

time... Thank you!

--- Feedback from NASA ----------------------------------------------------

“ Your hand is very responsive and does a good job of showing how well your

gesture control/recognition works. ”

Ron Diftler, Ph.D. Robonaut Project Manager, NASA/Johnson Space Center

Fantastic, will definitely give it a try.

acali (/member/acali/) (author) msfern

Let me know! I will add the next

in few hours with the full

algorithm. I need to translate all

my comments from italian to

english first :-/

coppe (/member/coppe/)

tech advances like 3D printers and people like you might some day make life

better for people who can't afford brand prosthetics, I'm an Orthopedic surgeon,

and I can see this being a great solution for people with a low income and severe

limb losses, great project, congratulations.

acali (/member/acali/) (author) coppe

I really appreciate your

comment, to be honest I would

like to make a 3D printed version

of the hand because using a

CAD project I would be able to

make a much better and

accurate design but the printer

still cost a lot and I can't afford

one. Maybe I ll just build one

someday since there are tons of

related step-by-step instructions

on this website :)
