Electric wheelchair: TiltDrive Mobility Chair
Type of project: Exploratory Research
Disability concerned: Motor disability
Topics: Autonomy, Mobility and travel
Status: In progress
The aim of this project is to develop a prototype electric wheelchair with four independent retractable arms, offering a very high degree of adaptability to terrain.
An electric wheelchair is much more than just a means of transport for its user. New solutions are making it possible to move around more independently, for example by offering the option of climbing stairs. However, these new possibilities often come with disadvantages that can prove distressing (high vehicle weight, lack of manoeuvrability, poor dynamic behaviour).
In particular, the dynamic behaviour of electric wheelchairs subjects users to significant forces when cornering, accelerating and braking.
Le comportement dynamique des fauteuils électriques soumet notamment les utilisateur·rices à des forces importantes en virage, en accélération et en freinage.
The partial or total inability to withstand these forces by muscularising the trunk increases the discomfort and risks of use. The auxiliary systems used to climb stairs are often heavy and require the user to ascend in a straight line.
Our project proposes to develop a prototype electric chair with four independent retractable arms, offering a very high degree of adaptability to terrain. This vehicle could climb curved staircases, allow conversations with people standing at the same height, compensate for unpleasant dynamic forces and keep the seat stable and upright at all times.
The originality of the project therefore lies in the future product’s ability to negotiate major obstacles such as steps or slopes, without compromising user comfort by using heavy, cumbersome systems. Driving dynamics would also be improved compared with currently available products.
Our target audience is electric wheelchair users in Switzerland.
