Motored Wheel Chair applicable to a variety of disabled

This paper describes a motored wheelchair that is suitable for disabled persons. A distinguish feature of our wheelchair is that a closed link mechanism is introduced. This link module changes conventional motored wheelchairs to computer controlled ones. It means that using intelligent functions of the computer, conventional motored wheelchairs can be navigated like an intelligent robot. Three examples of intelligent navigation functions are demonstrated. The first one is a motored wheelchair controlled by the head movement of the operator. The second one is a motored wheelchair with the image processing. Last one is a motored wheelchair with the remote sensing function.
