Self-Position Presumption of An Electric Wheelchair with a Function of All Directions Movements

Abstract

In a hospital site, our electric wheelchair performs an autonomous running. It runs referring a route map in the hospital. In this case, the wheelchair requires to seriously get self-positions in the site. It's reason why the wheelchair must reach the target areas or rooms by an autonomous navigation. We use trackballs and measurement modules to estimate the positions of the wheelchair. We report the presumption model for self-positions and experimental results.
