Tyr 3 is a modular prosthetic limb that mimics the layers of the human arm to provide superior comfort, utility, and beauty. It is a three tiered assembly of synthetic skin, muscle forms, and carbon fiber bones that can easily be customized for men, women, and humanoid robots. Tyr 3 is a dynamic platform that offers flexible solutions for the rapidly developing field of prosthetics.

Tyr 3 can be configured to meet a range of price points and capabilities. The arm can be a simple body powered prosthetic with a split hook or a highly advanced bionic arm outfitted with tools, sensors, skin, and a fully articulated hand. Instead of offering a single expensive arm to one demographic, anyone can purchase the core structure and upgrade it over time. It is a platform for companies and individuals to build new and exciting solutions based on their personal needs.

Role: Tyr 3 was my 2016 Senior Project at Drexel University. I spent six months creating a 70 page book detailing every aspect of the arm, as well as a full size articulating prototype.

The following page is only a brief project summary.

Next level comfort.

Comfort is the most important aspect of any prosthesis. No matter how advanced it may be, it's no help if it isn't worn. Tyr 3 was designed to be put on with one hand and uses a performance nylon blend that is tear resistant, light weight, and stretchy. The breathable fabric wicks moisture from the skin to the fabric's surface for evaporation.

Integrated tools.

The power of Tyr 3 comes from its versatility. In addition to storage in the forearm and palm for aftermarket tools, the entire surface of the arm (the skin) is a touch sensitive screen. Always powered and always with you, this is the ultimate mobile device.

Flexible solutions.

Tyr 3 can be configured to meet a range of price points and capabilities: As an affordable body powered prosthetic with a split hook or a highly advanced bionic arm outfitted with tools, sensors, skin, and a fully articulated hand. It is a platform for companies and individuals to build new and exciting solutions based on their personal needs.

Fully articulated.

The Tyr 3 hand is split down the center and along the palm, giving the hand flexibility and allowing it to bend inward. Around each finger is an elastic sleeve that fills the joints as they move and gives the hand a soft, natural grip.

Custom fit

The custom socket features plates that flex independently of one another.

Components

The main components of the arm, ready to be 3D printed.

Prototypes

The full scale articulated prototype next to my own arm.

Sketches

An early sketch on the arm, with callouts for each unique feature.

Attachements

This lower cost replacement for the hand can still be controlled remotely.

Shoulder design

A thick elastic band is strategically wound around the motors, bringing them to a slow stop as they reach the natural limits of their range.

CMF

Multiple parts are customizable to match the users personality.
