This short paper describes experiences in the development of several smart power wheelchair platforms across three different sites. In the course of the project, we have re-used several of the components (both hardware and software) despite differences in the base platform of the robots. We describe the different platforms, and discuss some of the challenges and results of our work.

Intelligent wheelchairs can help increase independent mobility for elderly residents with cognitive impairment, who are currently excluded from the use of powered wheelchairs. This paper presents three case studies, demonstrating the efficacy of the NOAH (Navigation and Obstacle Avoidance Help) system. The findings reported can be used to refine our understanding of user needs and help identify methods to improve the quality of life of the intended users.
