Realising Ideas (Day 1- Morning)
Log from DIY Prosthetic Socket
We start the process for designing a socket for a prosthetic arm by realising ideas on paper, these are some of the initial ideas that we took forward to prototyping. The step of defining the process of execution for the prototype is also something that...

Circuitry - Starting with electronics (Day 2-Morning)
Log from DIY Prosthetic Socket
This Tuesday morning we had to start with the electronics required for the functioning of the Prosthetic hand. We started by looking at existing components. We started to make the circuitry as per the scheme A and scheme B documents. Every component...

Form Fitting - Putting the Straps (Day 2 - Afternoon)
Log from DIY Prosthetic Socket
To continue on the path that we left yesterday, that is to improve the form-fitting of the prosthetic. After lunch we started working on this problem.We started by brainstorming some ideas for how to fix the problem.The use of straps was concluded from...

Soft matter(s)
Log from Graspex
For this year's Hackaday Prize I wanted to try something that has been little researched by the open source robotics community and, at the same time, that is related to my favorite field of robotics, wearable robotics, and has to do with what I think...

Project Session 4
Log from WEI ahead
Today, we're trying to print some parts of our prosthetic hand. We had some problems with the 3D Printer, and resolved them by downloading an other version of Cura (the software used to print). ADVICE : take time because the printing can take up to 16...

EMG sensor
Log from Publys: An open source biosensing board
"Electromyography (EMG) is an experimental technique concerned with the development, recording and analysis of myoelectric signals. Myoelectric signals are formed by physiological variations in the state of muscle fiber membranes." Basmajian&DeLuca:...

Bonus Model: Decoratively Carved Flexy Hand
Log from 3D Scan to Custom Soft Prosthetic Hand
The articulation geometries of the 3D printed parts in my silicone skin prosthetic hand are based directly on the "Flexy Hand 2" model by Steve Wood (http://enablingthefuture.org/upper-limb-prosthetics/the-flexy-hand/). I liked the Flexy Hand model so...

Limitations of SAMI and how it can be improved
Log from Smart Motor Driver for Robotics
Today I want to talk about the development of the project, limitations and future improvements that could be done to achieve an even better and powerful Smart Motor Driver. As mentioned earlier in a previous log there are some limitations with the hardware...

Prototype (Version 0.1) Review: Part 2--Ratchet System
Log from Hintha Modular Prosthetic Hand
Today I want to talk about the ratchet system that controls the 4th and 5th digits of the hand. The ratchet system is loosely based upon the commercial "Boa Closure" system that is commonly found in a variety of outdoor gear and, indeed, some traditional...

BCI update with alpha trigger for hand grip action
Log from 3D printed prosthesis with CV, BCI and EMG
First attempt of controlling the prosthesis with brain signal. The test is simple alpha trigger, using alpha signal to close and open the hand with a predefined grip pattern.

New EMG PCB finalized
Log from 3D printed prosthesis with CV, BCI and EMG
To make the acquisition of EMG signals more easier and more convenient, as well as to increase the number of channels acquired while maintaining the portability of the prosthesis, here is a much smaller PCB design for EMG sensor: Current size is 30x16...
