Dewclaw Prosthetic Thumb

Dewclaw V2

Welcome to the Dewclaw Prosthetic Thumb project, a FOS initiative to develop a nerve-impulse controlled prosthetic thumb with haptic feedback. This project is driven by a passionate individual with a vision to create an accessible and superior prosthetic thumb that everyone can contribute to and benefit from.

About Dewclaw

Dewclaw is a 2DoF prosthetic thumb controlled by EMG signals acquired from the users forearm (or any other place where one can get clean signals)

Background

When Dewclaw was conceived, there was limited information available on similar projects like "Third Thumb." While "Third Thumb" is an inspiring concept, Dewclaw aims to go a step further by providing documentation, advanced controls, and haptic feedback.

Project Subsystems

The Dewclaw project is composed of various subsystems, each playing a crucial role in achieving the vision:


Haptic Feedback: Unlike some other projects, Dewclaw incorporates haptic feedback to enhance the user's sensory experience and control.

Controlled Naturally: Dewclaw's nerve-impulse control system sets it apart, enabling users to command their prosthetic thumb with precision and ease.

Adaptability to Other Prosthetics: The Dewclaw project is not limited to just the development of an extra prosthetic thumb. The code and principles applied here are designed to be adaptable for use in various other prosthetics, including low cost replacement thumbs or fingers.
