We propose an obstacle detection sensor for operation support system aimed at preventing falling and toppling over of electric wheelchair. The LRF which is commonly used so far is excellent for detecting obstacles and the like. Since the obstacle to be detected is of the shortest distance within the range, it is difficult to detect steps, grooves on the floor surface and the like. Therefore, the proposed system arranges the laser ranging sensors in the form of an array and extends the reading range by reflection and angle adjustment of the plane mirror. In this paper, we describe the extraction of problems of LRF and the features of the proposed system.
