Designing of Autonomous Wheelchair for Movement in Standing Position

Abstract

Driving a manual wheelchair on any surface is a difficult task and past invented automatic wheelchairs are available at a very high cost in the market. The purpose of this paper, work is to propose an autonomous wheelchair that will reduce human effort while moving on a surface with inclination or declination and is available at a comparatively lower cost. One of the basic problems of user on manual wheelchair is to overcome barriers like kerb, rough surfaces, inaccessible surfaces etc. Though many research have been done in this field, but the question of overcoming these barriers always remains as a topic of discussion for many researchers. In our paper a motor operated & electronically hand controlled autonomous wheelchair concept which can overcome the architectural barriers to a considerable extent has been developed. This paper involves the design of an ergonomically designed battery powered wheelchair for multipurpose use. All the design parameters of wheelchair's are based on the standard design of stair in India. Major part of the paper focuses on the proposed design concept and mechanism and concludes by focusing upon the physical working model developed for the proposed design solution.
