Glove controlled 3d printed robot hand with Arduino.
The 3D printed hand has been going around the 'net lately, many people have been adding servos to make the fingers move. Dschurman put up an instructable that takes the robot hand the next level.
The design of the hand comes from a project called inmoov. It can be found here http://inmoov.blogspot.com. The plastic parts for the hand are open source and are available to download from the website.
The goal of inmoov is to build parts for life-sized humanoid robots, an interesting project in itself! If you have a 3D printer or and excuse to buy one, check it out!
Anyway, dschurman decided that he would like to update the design so that the fingers on the plastic hand can be controlled via your fingers in a glove. To accomplish this, the instructable shows you how to attach resistive flex sensors to a glove. An Arduino Uno reads the signals from the glove and controls the 5 servos that are used to manipulate the robot hand. Arduino code is provided.
I really want to see someone make "Thing" from the Adams family. Having this thing run around the house on Halloween would be sweet!
Dschurman estimates the project costs about $100-$150 in parts (as long as you have access to a 3d printer, otherwise this project may get a lot more expensive :) ).
Check out the video!
Regardless of the coolness factor, $150 for a prosthetic hand is a hell of a deal. Its amazing what you can do with a little programming and a 3d printer. You would think that this project is very close to be modified to allow someone to control it who has lost his/her hand. I can't help but to think of the scene in Star Wars where Luke is getting a prosthetic hand after his battle with Darth Vader!
