| Research Abstract |
We proposed a new type of scanning laser range sensor for recognizing three dimensional environment. The proposed sensor has advantages of small size, light weigh, and low power consumption with the help of micro electrical mechanical system technology. We developed a miniature two dimensional optical sensor which is driven by a piezoelectric actuator. We could succeed in making maps of natural terrains by using our developed sensor. By experiments, we comfirmed the validity of the new mechanism of a micro scanning laser range sensor. We could obrtain very good experimental results on sensing accuracy.
We also studied path planning and navigation for planetary rover by using the developed sensor. We proposed an extended elevation map, which included the effect of the size of the rover. We also proposed a path planning scheme based on traversability probability. And then we studied the fast navigation algorithm for planetary rover based on fuzzy resoning. The validity of the proposed methods was verified by computer simulation and experomental results.
