Grassroots Open Assistive Tech’s purpose is to document, curate, preserve, make accessible, and freely share assistive technology designs and information under open licenses, as well as providing coordination and education to affiliated communities.
We support disabled people in making their designs and builds available for public good, and in having free to use designs available to them for their own use.
By helping teach repair, maintenance, and customization skills, and providing an environment for those practices, we foster an ecosystem of repair and re-use, keeping disabled people mobile and independent, and keeping complex, expensive assistive technology devices from becoming trash and e-waste.
