A design of small-area automatic wheelchair

There are lots of handicaps and elders in the world. Many of them are not able to move as easily as normal people. It is useful if we develop an automatic wheelchair to help them move more freely. In this paper we proposed a design of small-area automatic wheelchair to help handicaps or elders be able to move easily in a small area. The most concern in this project is low cost with acceptable performance rather than high velocity or high accuracy. The design integrates several technologies to apply on the wheelchair, including wireless positioning, automatic mobile technology, and wireless communication. On the other hand, we proposed a design that duplicable information can be computed on server side, and information which is not duplicable can be computed in constant time. Therefore, our design of small-area automatic wheelchair can cost very little. We also proposed a design of building map information to make the whole design more complete.
