Motorised Wheelchair plays a pivotal role in the social life of Persons with disability (PwD) or elderly. Indian Motorised Wheelchair users scuffle to identify right Ergonomic Motorised Wheelchair because there are only very few designs developed by Ergonomic approach. The paper describes the methods to design an Ergonomic Motorised wheelchair and analyzes the design with Human Digital Models(HDM). Authors also demonstrate analyses of user comfort and some Ergonomic design methods. The analysis of user comfort while in the design stage using a Manikin by applying Indian Anthropometric Data makes the wheelchair a better fit for the Indian users. Thus, the design of user-friendly wheelchairs by HDM Ergonomic analysis. Authors also discuss RULA analysis of Motorised Wheelchair with 5th, 50th and 95th percentile HDM. The paper also estimates Indian Anthropometric Dimensions on HDM for Motorised Wheelchair. The paper also presents some design innovations on the footrest © IAEME Publication.
