BathMap: Designing a Platform For Mapping University Bathroom Accessibility
Bill Fan*, Stephanie Wang*, Shaini Nanayakkara, Min Kyung Lee, Lillian Chin, Earl Huff Jr.
Lack of information about bathroom access is a major pain point in disabled people’s access to public spaces — a problem known as the ‘bladder’s leash’. We designed a bathroom map platform that builds on a student organization’s participatory mapping activism and combines it with crowd-sourcing. We performed open-ended formative studies, and user-testing.
A Fast and Model Based Approach for Evaluating Task-Competence of Antagonistic Continuum Arms
Bill Fan, Jacob Roulier, Gina Olson
Determining whether a proposed continuum arm design can complete a specified task and load is computationally expensive due to the need for simulation. We introduce a novel method of analysis that eliminates the need for simulation, speeding up computation by 80x, and creates novel metrics for evaluating arm designs against tasks.
Linear Kinematics for General Constant Curvature and Torsion Manipulators
Bill Fan*, Farhan Rozaidi, Capprin Bass, Gina Olson, Melinda Malley, Ross L Hatton
Inspired by octopus arms, helically-wound muscles greatly increase continuum arm workspaces, but they are more difficult to model and control. We present a novel application of Lie theory to simplify the modeling of constant twist soft robots, and unify modeling across different designs. Won 3rd place best workshop poster.
