The harsh winter in Niigata, Japan brings heavy snow, which can pose problems for residents — particularly the elderly — who are faced with the laborious task of clearing it from driveways and entrances.
To the rescue comes Yuki-taro, an autonomous snowplow robot developed by a team of researchers from five Niigata-area organizations.
The friendly-looking Yuki-taro measures 160 x 95 x 75 cm (63 x 37 x 30 in.) and weighs 400 kg (880 lbs).
Armed with GPS and a pair of video cameras embedded in its eyes, the self-guided robot seeks out snow and gobbles it up into its large mouth.
Yuki-taro’s insides consist of a system that compresses the snow into hard blocks measuring 60 x 30 x 15 cm (24 x 12 x 6 in.), which Yuki-taro expels from its rear end.
The blocks can then be stacked and stored until summer, when they can be used as an alternative source of refrigeration or cooling.
Researchers continue to work on reducing Yuki-taro’s size, weight and cost, and they hope to make it commercially available in five years at a price of less than 1 million yen ($8,300).
It is unclear whether or not the researchers intend to further enhance the robot’s “cute” factor, but they might ought to consider attaching a pair of pointy ears. O-negai!
