Considerations on the Concept of Cost-Effective Power-Assist Wheelchair’s Subsystems (Case Study and Initial Evaluation)
Abstract
The given paper deals with a concept of cost-effective power-assistant wheelchair. An analysis of the market situation and recent technical achievements is done in the beginning. On its basis, a set of solutions, suitable for the development of such wheelchairs, has been composed. It is shown that the key features of the considered concept are segmented electrical motor and drive, sectioned battery pack, modular charger and an ANN matrix that provides easy and intuitive interfacing of sensor networks, pseudo-bionic feedbacks and decision-making unit. Within the scope of the work, a 3D model has been developed and 3D modelling has been conducted. As a result, certain drawbacks in construction and placement of elements have been revealed, as well as modification of the concept has been proposed.
