Design and fabrication of a statically stable stair-climbing robotic wheelchair

Purpose – The purpose of this paper is to present the mechanical design and stability analysis of a new stair‐climbing robotic wheelchair.Design/methodology/approach – A prototype stair‐climbing robotic wheelchair is constructed comprising a pair of rotational multi‐limbed structures pivotally mounted on opposite sides of a support base. The short arm, long arm, and triangular support structures within each rotational multi‐limbed structure rotate under the actuating effects of epicyclical gear trains.Findings – The robotic wheelchair ascends and descends stairs in a statically stable manner and has an efficient planar navigation capability.Research limitations/implications – In its current state of development, the robotic wheelchair is controlled and powered remotely via umbilical cords rather than an onboard processor and power supply.Practical implications – The robotic wheelchair provides an effective solution for enhancing the mobility of the elderly and disabled.Originality/value – The rotational m...
