Open-source bionics for everyone
OpenBionics is an open-source initiative that focuses on the development of affordable, light-weight, modular, adaptive robotic and bionic devices that can be easily reproduced using off-the-shelf materials.
The initiative was originally inspired by the Yale Open Hand Project and was supported by the European Commission through the Integrated Project no. 248587, "THE Hand Embodied" (2010–2014), within the FP7-ICT-2009-4-2-1 programme on Cognitive Systems and Robotics.
Since 2019, OpenBionics has collaborated with the New Dexterity research group at the University of Auckland to deliver a new class of open-source, affordable, dexterous bionic devices.
Every device released by the team comes with full hardware files, firmware, and documentation, distributed under the Creative Commons Attribution-ShareAlike 4.0 International License so that researchers, clinicians, and makers can build, adapt, and redistribute them freely.
What guides the work
Open-Source
Every design, schematic, and firmware release is published under a Creative Commons Attribution-ShareAlike 4.0 license — free to study, build on, and redistribute.
Affordable
Devices are engineered around accessible components and fabrication methods so that researchers, clinicians, and makers can build them without specialised infrastructure.
Lightweight
Material selection and structural design favour compact, low-mass solutions that are practical for daily wear and laboratory experimentation alike.
