This mould is the special material to house the amputated knee or simply it acts as a major connection between knee and the foot. Many prosthetics that have been in the market lately have used carbon fibre as the base. Although carbon fibre is strong...
In the previous log I had mentioned about the design of the mold for housing the amputated knee region. This mold has to be connected to the foot by some means. There are several parts available in the market which can perform this function. But one...
Since the design of the socket and the connector is completed, it can now be attached to complete the bionic leg. The whole setup is very simple and it consists mainly 3 parts. The Socket A simple cast/mold is made from silicone rubber after measuring...
What The aim of this project is to develop a hardware and software system capable of semi-automatic grasping of objects. For this a prototype hand as well as a software control system are being developed. The central idea is that by giving the hand the...
This log describes the design of the hand chassis, and the mechanical transmission system. The electronic circuitry and sensor modalities will be discussed in a later entry. Design Considerations I chose to go with a five finger anthropomorphic...
Let's look at the functionality for both the physical hand prototype, as well as its low- level control API. Firstly, I will talk about the hand prototype’s design, cost, ability, and stability before discussing the low-level API’s design and performance. The...
This log is introducing the development process and methods employed for creating a software control system for the hand prototype. The high-level control software’s aim is to make its own grasping choices, requiring only minimal human input. The grasp...
Not an euphemism, just a weird skiing accident. They took two weeks and three x-rays to diagnose it! I'm known in my school as "the hand guy" (for this and other prosthetic/hand/arm related projects I'll post in the future) and now they think I...
The 3D printed parts - Thingiverse user embeddedjunkie's "Robotic Hand" model to use as a prosthesis model and some custom parts for hand tracking - are printed out and ready for assembly. These parts will be modified to attach the buttons and a better...
The Arduino Mega attachments are completed on two pieces of prototyping board. On one board, there are the attachments for the 6 servos which control the prosthesis model and the arm attachment. The other board connects to the analog inputs of the arduino...
All the 3D printed parts - the prosthesis model and the hand tracker - are assambled and modified to house the buttons. The prosthesis is attached to a piece of wood along with the servos that pull the strings attached to the fingertips. Also the potentiometers...
The code that controls both the prosthesis model and sensing attachments is ready to be used. At this point the code only runs one micro servo as this is a prototype.
Sept 21st, 2017 - 5pm- we introduced the challenge to new team members, took a vote since we have less than a month and it looks like we're going to attempt an entry- discussed different CADing software to use for this project - we have a previous...
- We split the team into 4 subteams for the next week to get components ready for 3D printing:TEAM 1 Timeline: Aim to complete by Sunday/Monday (It will be difficult for team 4 (and perhaps team 3) to start before team 1 completes their work) Members:...
The motion capture hackathon took place last week . It was great to see the Chordata system used on so many different projects! Here's a quick recap of the work done: Arianna: a great prototype for an easy low cost DIY sensor attachment suit. Antonio:...
