| Research Abstract |
With dramatic increase in the households with elderly people in Japan, accidents by elderly people while removing snow in cold regions have been increasing recently. The operation of a multifunctional snowplow, which has many control levers, is difficult for elderly people because of the skill and power required to control the levers. In this study, therefore, the performances of a newly developed autonomous snowplow and a snow melter, that can be handled easily and are safe, were evaluated. This study presents experimental results on the operation of an autonomous test model equipped with a vision sensor for recognition of landmarks and a snow melter that can carry out high-speed and efficient snow melting work by utilizing foam of the exhaust gas.
In the experiments, the locomotion of the autonomous snowplow was correctly able to move along the target path by using a vision sensor and landmarks even if the course was slippery and uneven. In addition, the safety of the work was improved because the automatic monitoring system was able to forecast the danger of the work. The snowmelt speed by utilizing the foam of the exhaust gas becomes, 10 times farther than the case in which there is no foam. In future research, efforts will be made to shorten the time for image processing by the vision sensor will be shorten by optimizing the design of landmarks and by combining control techniques.
