Powered wheelchairs are popular mobility aids for most disabled patients and elders. Most of powered wheelchairs are manipulated via a conventional joystick. The powered wheelchair user has to control the direction and velocity of a powered wheelchair in a very narrow joystick operation range. Therefore, the user's joystick command may be very sensitive to the wheelchair motions. In addition, such...
Autonomous robotic wheelchairs play important roles to disabled persons or elders. In general, an autonomous robotic wheelchair includes the techniques of obstacle sensing and avoidance, local path navigation, and friendly interactions with users when compared to conventional powered wheelchairs. Most of researches on autonomous robotic wheelchairs used the personal computer as the supervisory controller...
Autonomous robotic wheelchairs are widely discussed in recent years. Most of autonomous robotic wheelchairs were developed based on rich computation architecture to deal with complicated navigation efforts such as personal computers or embedded computers. However, such rich computation architectures increase cost of robotic wheelchair when compared to conventional powered wheelchairs. At the same...
Wheelchair is one of the most important mobility aids for the disabled people and elders. In this paper, we propose the human-oriented robotic wheelchair design and implementation based on the considerations of convenient driving in narrow space with non-straight paths, active collision avoidance, autonomous navigation, real-time user joystick command justification, intelligent fusion of user joystick...
