Abstract
This paper is described about a bump detecting system using a Laser Range Finder for an electric powered wheelchair. In recent years, the wheelchair diffuses for elder. Thereby the increase in an accident becomes problems. Especially the fall from a platform, derailment in a sewer, etc. have also caused a death accident as a serious accident. So we propose the detecting system that the Laser Range Finder is attached to the side part of the wheelchair, the front is scanned perpendicularly. The system can detect not only an obstacle but the bump. In the experiment, we have carried out experiments on flat, obstacle, bump, and have checked that it was correctly detectable.
