In Japan, the number of elderly households facing difficulties in snow removal work is increasing due to the rapid aging and depopulation. Moreover, because of the declining birthrate, human resources needed for the work are insufficient. Therefore the elderly are forced to do the snow removal work on their own, and as a consequence serious accidents may occur during the work. Currently, as a means for solving this problem, there are snow removal substitution services and construction of electric road heating. However, they are not definitive solutions since they are very expensive. The purpose of this study is to develop an autonomous robot system which can perform snow removing with low cost and simple construction. Through the experiments using the prototype, and the cost estimate that assumed practical use, the effectiveness of this system was confirmed.
