More objects for active vision system
Log from 3D printed prosthesis with CV, BCI and EMG
I have been wanted to increase the number of supported objects for the active vision system for the prosthesis, as it means that there will be more supported grip patterns corresponding with the objects. Here is my weak attempt of creating a banana classifier....

ALL 3D STL FILES UPDATED
Log from 3D printed prosthesis with CV, BCI and EMG
I have logged all the STL files necessary to create this prosthesis. I have also included 2 .3mf files for the elbow module and the wrist module to guide everyone through the assembly process. Have a look at the video below to understand how to use the...

Linkage used for design of finger module
Log from 3D printed prosthesis with CV, BCI and EMG
Just a recap of what I used to design the prosthesis.Since I am an electrical engineering student, I do not have much experience with mechanism design and simulation. So I have been trying to find an easy and intuitive tool for me to do so. The trajectory...

All software and firmware updated
Log from 3D printed prosthesis with CV, BCI and EMG
The Github directory of the project is now usable, and I have updated all the source code that I have written, including:The application GUI for the hand moduleThe general usage oscilloscope: I use it to log EEG signalsThe SSVEP oscilloscope: derived...

The Avatar Program
Log from Horizon
When it comes to technology, humans have been able to be far away while being in their location. If this is possible, why is it that there can not be 1 user in 2 locations? This would require a user, a willing catalyst and a connection between the two....

Back to Haptic Games...
Log from HapticGames
... sort of :) Here we got inspired from the prosthetic Nerf gun (There exist also the idea of a mind controlled one .... hmm, looking at the mind flex controller ...). And since the CCCamp this year was a bit dusty, we considered that the world needs...

First development of prototype finger
Log from ARX Hand Project X1
17 Nov 2017 "I've designed an improved finger mechanism for the prosthetic. This design improves the overall range of motion as well as limiting the range of unintended motion. It is also slightly more slender than the previous design but grasping strength...

V3 finger design
Log from ARX Hand Project X1
4 Mar 2018 A third finger design iteration, made to look more aesthetically like a fictional humanoid finger. The design is based off of a ball jointed style of design for each joint, but using a hinged based system. Design has also been optimised for...

Motorised V3 Finger
Log from ARX Hand Project X1
16 Mar 2018 "New finger design~This version uses a different pulley system compared to the previous that's more commonly used in other prosthetic hands. Changes have also been made to the choice of motor as well as the aesthetics of the finger. Improvements...

Experimental High Torque Bi-directional Ratcheting Mechanism
Log from ARX Hand Project X1
Actually, would this joint be considered a ratcheting joint or a joint with indents? This design looks into the use of a ratcheting mechanism for use within the wrist section of the arm. I'm not entirely certain on what mechanism would be...

A fourth and fifth axis adds no slop
Log from LadyBug BEEFY: 3D printer motorized microscope
In the original LadyBug, I used a teeny tiny stepper motor to add rotational capability for not just 2D scanning, but 3D scanning of a small sample: I wanted to do the same thing here. So I made a bracket for a standard Nema Stepper motor:...

Implementation of a 3D Scanner Arm
Log from 3D Scanner Arm Control Board
Abstract Three-dimensional scanning technology has reduced dramatically in price and ease of implementation. Unfortunately, these low-cost, three-dimensional scanning systems lack intuitive tracking during the scanning of a part. This leads...

Ideal Scanning Speed to Optimize Low Cost Scanner Use
Log from 3D Scanner Arm Control Board
Abstract The goal of this study is to find the optimal scanning speed for the best scan accuracy when using a low-cost scanner. This will be accomplished by using a Sense™ 3D Scanner as the low-cost scanner in this pilot study. Each iteration...

Motivation and Research
Log from Discrete Motor Driver
This project was inspired by the development of a control board for a 3D scanning apparatus for prosthetic socket design. I wanted to design an analog version that could drive a stepper motor similarly to the overpowered design that previously...
