Exploratory research to develop an innovative electric wheelchair

Situation

The objective is simple: compensate as much as possible for the forces felt by users while driving. On a bend, the lateral force experienced can cause discomfort, especially if the user’s core muscles are impacted by a disability. The same applies to acceleration and braking. As well as compensating for the forces experienced, the concept of four independent arms would ensure much smoother and more versatile dynamic behaviour compared to many other electric wheelchairs. In particular, the prototype could adapt to uneven terrain, negotiate obstacles, and even go up and down stairs!

The developments resulting from this project aim to improve the quality of life for people with disabilities who live in urban areas that are all too often poorly adapted to the use of mobility aids.

Building on the mechanical concept that has already been the focus of SCI-Mobility’s research, we must now establish a control strategy and improve the prototype plans in preparation for its construction.

Course of action

Supported by the Research Foundation for People with Disabilities (FRH), SCI-Mobility is launching an exploratory research project between now and November 2024. It is the final phase before the prototyping process. SCI-Mobility’s vision is to ensure that the prototype satisfies the needs of everyday users of electric wheelchairs as far as possible. For this reason, interviews will be conducted with two individuals directly concerned by such issues, contributing to the creation of a questionnaire designed to reach as many affected people as possible across Switzerland. The survey results will form the basis for the development of a prototype that satisfies their specific needs and expectations, while ensuring that developers do not get sidetracked by albeit interesting engineering concepts that do not address the immediate requirements of people with disabilities.
