InMoov finger prosthetic project by hairygael Jul 14, 2013

Description

Since InMoov hand has been released on Thingiverse, I receive demands on how to use it as a prosthetic. Lately a french FabLab asked me if they could use InMoov for their project. I new the initial design was not adapted for that matter and I think it could be better done if I kept the prosthetic perspective in mind.
So this research can be used for the Bionico Prosthetic project or any other prosthetic project as long as it is not with commercial uses.
The goal is to keep all motors within the palm and to create mechanicaly actuated fingers.
I haven't printed it yet so please beware this is uploaded only for other members of the Bionico project to test my design. There might be things wrong.

Hello,
we are french students and we are working on a project for school. This project is an artificial limb. We are using your project and we would like to have your mounting scheme. Thank you in advance.

Hi hairygael,
Is it possible to obtain the phalange gear file without the other phalanges and the actuator in two files. I wish to do the phalange in stainless steel and the actuators by water jet cutting a .dxf or .dwg file will be nice.

Instructions

This finger has two types of motors, make sure to download the correct casing and FingerWorm for your purpose.
This is meant to be assembled using a servo motor Corona DS238HV or a DC brushless motor with planetary reduction 154:1
from Pololu.
The motor used:
pololu.com/catalog/product/1109
The driver used
pololu.com/catalog/product/2130

With the servo Corona DS238HV use these files:
-FingerWormV1.stl
-ServoHolderV2.stl
-PhalangeV6.stl
-ActuatorsV3.stl

With the planetary gear motor use these files:
-FingerWormV2.stl
-MotorHolderV3mid.stl
-MotorHolderV3top.stl
-PhalangeV6.stl
-ActuatorsV3.stl


Update 18/07/13 PhalangeV1 is now PhalangeV2.
Update 20/07/13 PhalangeV2 to PhalangeV3.
Update 23/07/13 PhalangeV3 to PhalangeV4, ActuatorV1 to ActuatorV2
Update 24/07/13 PhalangeV4 to PhalangeV5
Update 25/07/13 ServoHolderV1 to ServoHolderV2 to get more flex on the finger
Update 13/08/13 PhalangeV5 to PhalangeV6 for even better flex. Added MotorHolderV3mid and MotorHolderV3mid for the planetary gear motor.. Added FingerWormV2 for the planetary gear motor.

There is no instructions yet, as this is a work in progress.

no thumbs?

Hi, no thumb. :)

This is not a hand yet. it is only one finger and needs to be printed by beta testers, before to go on with the rest of the hand. Being away from my 3d printer, I can't test it, so I'm relying on others.
