"Open Hand Project" which makes cheap advanced robot prostheses with 3D printers

Open Hand ProjectIs an open source project with the goal of making it easier for people who have lost limbs to obtain robot prostheses. Robot artificial hand completed as the result of this project "DextrusIs a high performance robot prosthesis that can be created using 3D printers and can grasp the egg gently and grasp the pen with the fingertip while the production cost is less than $ 1000 (about 100,000 yen) .

This is Dextrus. A robot that utilizes an electric motor instead of a muscle, a steel cable instead of a tendon, a plastic part with a 3D printer instead of a bone, and a rubber coating covering the plastic part plays a role of human's skin It is a prosthetic hand.


We used parts of ABS resin outputted by 3D printers without using titanium and carbon fiber materials used for state-of-the-art robot artificial hands, which means that we succeeded in greatly reducing costs.


In addition, Dextrus is designed to make it easy to exchange parts.


And all parts are controlled by electronic equipment, it seems that the whole is designed to perform natural operation.



Dextrus has twoElectromyographPaste and manipulate the prosthesis by reading the signal of the body.


The producer is Joel Gibbard living in Briston, England.


Dextrus can gently and firmly grasp objects of various shapes but this is because the cable passes through each finger of Dextrus and it can operate finely from the joint to the tip, And that.


Grab eggs ......



It is also possible to have a bag.



In addition, since it is possible to individually operate each finger and to detect what interrupts the action, detect a crayon ......


I grasp it.


Hold firmly even if you release your hand.


You can also move and move crayons by moving your fingertip.



Dextrus is an existingProstheticSince it is possible to connect to Hotetsu, we do not need any custom for connecting.



"I am proud that I have this arm and give me confidence" is that Cock's Liam Corbett who is testing Dextrus after losing his arms with meningitis two years ago Mr.


From calculation results and actual tests, Dextrus can operate for 8 to 12 hours with lithium ion battery.


This Open Hand Project is currentlyIndiegogoWe are seeking investment, and at the stage of writing an article you can get a robot artificial Dextrus and a battery charger, an electromyograph and 100 replacement electrodes with a contribution of $ 650 (about 65,000 yen) The plan has 9 frames remaining.


The deadline for this project is local time at 11:59 pm on October 9.
