About the Project
Despite major advances in prosthetics, most devices remain prohibitively expensive and are developed in specialized labs — limiting who can use and improve them. Digit Robotics was created to change that. Our goal is to provide a prosthetic development kit many people can actually wear and experiment with, so development happens faster and more broadly.
The kit integrates advanced functionality — including pressure sensing and electromyography (EMG) control — while keeping costs low. It’s intentionally customizable rather than modular: every mechanical part is 3D-printable so creators can tailor size, shape, and performance without waiting for expensive tooling.
Beyond helping amputees, this platform is valuable for able-bodied users and researchers: interacting with robotic limbs can support neuroplasticity, and the kit provides a hands-on way for developers to learn how sensors, control loops, and mechanical design combine into functioning prosthetics. Our aim is to reduce the cost and increase the pace of real-world prosthetic innovation.
Key Features
Electromyography (EMG)
Reads muscle electrical signals to provide intuitive, proportional control — enabling natural movement mapping from user intent to actuation.
Haptic feedback
Real-time tactile feedback driven by pressure sensors gives users a sense of touch and improves grip control during tasks.
Realistic motion
Designed to replicate human-like flexion, the mechanism focuses on smooth, coordinated joint movement for everyday tasks.
High torque
Powerful, efficient actuators provide reliable grip strength for common activities while remaining compact and energy-conscious.
Compact design
Lightweight and low-profile so the kit can be comfortably worn and tested in real-use conditions.
Non-invasive
No surgery or embedded hardware required — the system is fully wearable and reversible.
3D-printable & customizable
Every mechanical part is printable so developers can iterate fast: reprint geometries, test new fingertip materials, or tune fit for users.
Developer-friendly
Designed for learning and rapid prototyping — ideal for students, researchers, and makers experimenting with sensors, control, and haptics.
