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.

GOAT Learning Lab: Meet the Power Wheelchair
GOAT Space, behind Bookmark Bookstore, 10th & Broadway, Oakland
Details of GOAT Learning Lab: Meet the Power Wheelchair
Ever wondered what’s actually inside a power wheelchair—or why two chairs can feel completely different? We’ll explore several power wheelchairs, identify their major components and features, compare drive systems, and talk about how design choices affect everyday life.
No experience needed, questions are welcome.Physical location: GOAT space (behind Bookmark Bookstore in Oakland)

Details of GOAT Learning Lab: Power Wheelchair Checkup
Learn a simple visual and hands-on inspection of a wheelchair. We’ll look for loose hardware, worn parts, damaged cables, caster problems, tire issues and other signs that something may need maintenance - plus when to stop and get additional help.

Lesson plan: 2026-09 Learning Lab NotesGOAT Learning Lab: Wheels, Casters & Hairballs
GOAT Space, behind Bookmark Bookstore, 10th & Broadway, Oakland
Details of GOAT Learning Lab: Wheels, Casters & Hairballs
Wheelchair wheels collect an astonishing amount of hair and debris. We'll learn how common wheel and caster assemblies fit together, remove selected wheels, clean them, inspect the hardware and put everything back together.

GOAT Space, behind Bookmark Bookstore, 10th & Broadway, Oakland
Details of GOAT Learning Lab: Power Chair Batteries 101
What powers a power wheelchair? We'll open up a chair, find its batteries, look at how they're connected and discuss common battery problems. Participants will practice documenting connections, disconnecting/reconnecting batteries and doing basic voltage checks. No experience needed, questions are welcome.

Inclusive design and disability technology — whether it uses AI or not — aims to make life easier and more fulfilling for people with disabilities. In this moderated discussion, two experts share their perspectives on the possibilities and perils of contemporary advances in the field of assistive technology.
Jutta Treviranus, Director and Professor at the Inclusive Design Research Centre, within the Ontario College of Art & Design University, will speak to the ever-expanding role of AI. As a statistical replicator feeding on available data, AI inexorably favours the average, popular, or profitable. Disability means you are an outlier in population data and the things you need have no economies of scale. The only common data characteristic of disability is sufficient distance from the majority that common things are not designed for you. While AI is uncannily good at helping achieve the average, AI eliminates difference. When decisions are made about people who are not average, this can lead to mechanized digital eugenics. This has grave implications for disabled people and minority communities but also for human survival.
Liz Henry, Executive Director of Grassroots Open Assistive Tech, will speak to the notion of designing ourselves as “sustainable cyborgs.” There exist many efforts to create assistive technology, often with fabulous cutting-edge engineering. People also love to create custom tools and materials for a particular disabled person, at hackathons and so on. What does designing for repairability and maintenance mean? What’s the experience like for someone to get their wheelchair repaired? What happens to the miracle devices when they break? And how can we save ourselves from the mountains of garbage and e-waste that overwhelm us? Henry will discuss repairability, design, and the promises of open source and open culture!
