Traditional wheelchairs used by the elderly and people with severe disabilities have some limited functions and flexibility. Their users often need help from nurses or relatives. Several teams are currently at work to develop robotic wheelchairs to overcome these limitations. For example, researchers from the University of Essex and the Institute of Automation at Beijing are developing the RoboChair.
RoboChair will be equipped with a vision system and a 3G wireless communication system. It will be able to avoid collisions and to plan a path. Meanwhile, Professor Ray Jarvis of Monash University's Intelligent Robotics Centre in Australia, is building another robotic wheelchair which will help people to travel off the beaten track (PDF format, 1 page, 131 KB). His prototype system combines robotic navigation with a four-wheel drive. It automatically adapts itself to the user's capabilities and takes control when needed. You'll find more details and a picture in this overview. Keep in mind that there are still major issues to solve, such as security and costs, before these robotic wheelchairs become available.
