Project Sparthan

Simple Prosthetic Artificial Hand

More About us

What we do:

More than 3000 children every year are born with a congenital limb deficiency in the United States alone. These children will change their prosthetics devices once every 6 months on average, making the purchase of a high end, automatic prosthesis not affordable for most families.
The advent of affordable 3D printers spawned numerous customizable and very affordable prosthetic hand models. These devices can be modified to fit the children as they grow, at a relatively low price. However, these prosthetic hands leave a lot to be desired in functionality. Most of these devices can only allow coarse finger control, placing it in stark contrast to commercial automatic hands.
Our Team is committed to take the concept of modular prosthetics a step further, continuing to bridge the gap between expensive robotic arms and 3D printed prosthesis. We are designing and developing Sparthan, a modular electronics kit, compatible with existing prosthetic hand models, which will enable intuitive hand control and movements.


This is a developer preview of the Sparthan module. We designed it to be compact and powerful, easy to embed in existing 3D printable prosthetic hands.

ACM - Interactive, Mobile, Wearable and Ubiquitous Technologies

Kirill A. Shatilov, Dimitris Chatzopoulos, Alex Wong Tat Hang, and Pan Hui

Although many children are born with congenital limb malformation, contemporary functional artificial hands are costly and are not meant to be adapted to growing hand. In this work, we develop a low cost, adaptable and personalized system of an artificial prosthetic hand accompanied with hardware and software modules. Our solution consists of a consumer grade electromyography (EMG) recording hardware, a mobile companion device empowered by deep learning classification algorithms, a cloud component for offloading computations, and mechanical 3D printed arm operated by the embedded hardware. We focus on the flexibility of the designed system making it more affordable than the alternatives.

This paper describes the development and testing of a low-cost three-dimensional (3D) printed wearable hand exoskeleton to assist people with limited finger mobility and grip strength. The function of the presented orthosis is to support and enable light intensity activities of daily living and improve the ability to grasp and hold objects. The Sparthan Exoskeleton prototype utilizes a cable-driven design applied to individual digits with motors. The initial prototype is presented in this paper along with a preliminary evaluation of durability and performance efficacy.


International Conference on Engineering Design

Tat Hang Wong, Davide Asnaghi, Suk Wai Winnie Leung

New advances in both neurosciences and computational approaches have changed the landscapes for smart devices design serving mobility-related disabilities. In this paper we will look at how we integrated affordable robotics and wearable sensors through our mechatronic product platform to enable accessibility of the technology in both the power prosthesis and neurorehabilitation space.
