Worry Prosthetic Electronics
Log from Musical Prosthetics
Once I felt like I had the body of the prosthetic built, it was time to start experimenting with the sound component of the design. I originally thought that the prosthetic would have two SoftPot Membrane Potentiometers on each of the hands, and be played...

Happy Prosthetic Starting Off
Log from Musical Prosthetics
As I started in with my idea for a happy prosthetic, I knew that I already had a few constraints, the first being that the happy prosthetic needs to somehow tie the other two prosthetics together, uniting them both visually and conceptually. I also know...

Happy Prosthetic Laminating Wood
Log from Musical Prosthetics
Now that I have a vision for success, it is time to figure out how to make this prosthetic function. I envision this prosthetic being made out of steel wire with a circular base wire at the top which everything will hang from. I want to explore laminating...

Happy Prosthetic Finishing Touches
Log from Musical Prosthetics
Once I had the petals made it was time to start experimenting with how to use them. I started to string them on some spare wire I had just to see how much space I would need between each petal, and how they acted, and I was very pleased. It turns out...

Happy Prosthetic Electronics
Log from Musical Prosthetics
For the happy prosthetic, I am inspired by the motion of a hoola-hoop. Each of the petals will bounce as the wearer moves as if playing with a hoola-hoop. I will capture this movement with a Hall Effect Sensor, which is a magnet sensor. This digital...

Musical Prosthetics In Action
Log from Musical Prosthetics
Once I had all the prosthetics in order, I started to test them out and make music with them. I learned so much as I was trying to use them- about myself and the prosthetics. First, I started with the worry prosthetic, which worked pretty much how I...

First design of the prosthesis
Log from 3D printed prosthesis with CV, BCI and EMG
First design of the prosthesis with only 8 DOF. This design is frail and does not have high dexterity.This design does not have wireless support, everything is controlled using a built-in serial controller.

Processing application to control prosthesis
Log from 3D printed prosthesis with CV, BCI and EMG
An application is written to control the prosthesis from a PC. User could control the prosthesis by changing an animated arm on screen. The prosthesis will then be updated with new data through serial communication and calibrate itself. The application...

Fast active vision system developed for prosthesis
Log from 3D printed prosthesis with CV, BCI and EMG
The following video shows the hybrid active vision system designed for this prosthesis. This system consists of an object tracker and an object recognition system that finds an object of interest, chooses the most appropriate grip pattern and waits for...

Active vision system in action with prosthesis
Log from 3D printed prosthesis with CV, BCI and EMG
Putting the active vision system into the prosthesis. Demo videos:Vertical movements:Horizontal movements:Putting everything together:Rotated viewpoint for grip action:Here only the active vision is working, there is no consent from the user (BCI or...

Another step towards our goal: prosthetic arm control demo
Log from uMyo - wearable EMG sensor with wet/dry electrodes
The next step in uMyo development is combining data from multiple sensors. And since a significant part of our goal is using uMyo in prosthetics control - this demo shows how it can work.In a sense it's a remake of our effort from 2019 based on uECG...

Actuation / Transmission Mechanisms
Log from OpenBionics Affordable Prosthetic Hands
Introduction In our hand, actuation is generated with only one motor and transmitted through tendon routing to the fingers with two separate, decoupled mechanisms: 1) A locking mechanism for the thumb and 2) A selectively lockable differential mechanism...
