One-Arm Drive Manual Wheelchair Public
Downloadable ContentDownload PDF
Traditional manual wheelchairs use both arms for operation. Building upon previous projects, the goal of this project was to create an accessory, installable on a standard wheelchair, which would allow full control of a wheelchair with only one arm while addressing problems in other commercial and student designs. After preliminary analysis of three one-arm designs, a removable, lever-operated accessory was developed which could fit several popular wheelchair models. The propulsion uses one-way sprag clutches, the steering is cable based, and braking uses bicycle disc brakes. Specialized parts were used sparingly to improve manufacturability and cost. The accessory was evaluated against two other existing designs and showed marked improvement in propulsion, safety, and user comfort.
