A Novel Stair-Climbing Wheelchair with Variable Configuration Four-Bar Linkage - Mechanism Design and Kinematics

摘要

This paper describes the mechanism of a novel multi-wheel stair climbing wheelchair. The necessity of the mobility aid technology for elderly and handicapped people which has "Minimally-invasiveness for historical environment" are described, and with this goal, a novel multi-wheel stair climbing wheelchair with variable configuration four-bar linkage is proposed. Its mechanical design, principle of operation and kinematics are mainly illustrated.
