*UPDATE* Just wanted to add a bit of how posting this Instructable has positively impacted me. Besides the wonderful reception and feedback I received in the contests and the success it has had in the contests it helped me define my interests. I've always loved robotics and prosthetics (and similar helpful devices) is a new interesting and beneficial application for it. Posting this project got me involved in a prosthetics research team and we may even be using this exact arm, or one similar, for testing. Thanks all!
Do you live with only one hand, or ever feel two just isn't enough? Well now you can make another! This project combines two very cool things: an arduino voice recognition shield and an open-source 3D printed robotics project called InMoov
. Basically what I've done is modify the InMoov hand/forearm to be usable as a prosthetic (or additional appendage) and add a VR (voice recognition) shield to receive verbal commands and then make corresponding motions with the hand. The advantage of voice control is that it doesn't require muscles and is more flexible to different physical conditions (also hands free!). My program includes 15 general hand gestures and actions for everyday living!
When I was looking into myoelectric arms
kept thinking that the functionality wasn't worth the thousands of dollars. While mine isn't as fancy as some it's remarkable what you can create with desktop 3D printers, an arduino, and servos! I think the coolest part is the customization: the printed parts can be scaled to make an accurate prosthetic for anyone.
Although this project can look intimidating, the entire time taken (if you work on the electronics while parts are printing) is about 14 hours! See it in action!
