A Wheelchair With Two Automatically-Controlled Speed Ranges

By Stefanov, Dimitar; From Smart Homes to Smart Care: International Conference on Smart Homes and Health Telematics (ICOST 2005), Vol. 15, No. 1, pp. 124-131
Publication Date: 2005

Paper focuses on the design of a universal small-sized wheelchair for people with limited outdoor activity and narrow home space. The chair contains two distinctive features: (1) a special gear that does not need speed synchronization to change its reduction ratio, and (2) a controller that automatically chooses appropriate velocity range according to terrain characteristics. A technological evaluation of the system is included. The project design was created via a partnership between the Cardiff and Vale National Health Service Trust in Cardiff, United Kingdom, and the Institute of Mechanics at the Bulgarian Academy of Sciences. This paper was presented at the 2006 International Conference on Smart Homes and Health Telematics.
