The robot - which stands with two legs on each ski and grips ski poles with its middle legs - was developed by experts from the by Shanghai Jiao Tong University.
This snowmobile conversion was invented by Virgil White, a Ford dealer in New Hampshire, who built his first in 1913 and patented it four years later. The kit included skis made of wood and metal, a dual-wheel rear axle from a Ford TT truck, and tracks for the wheels.
White sold the kits through Ford dealers, starting in 1922. The kit was $400, or you could buy a converted car for $750. There weren’t a lot of roads at the time outside of cities, and they were seldom if ever plowed, so the Snowmobiles were popular with doctors and mail-carriers.

Carl Eliason’s hand-built 1924 motor toboggan is on display in Sayner’s Snowmobile Museum, and Eliason’s design was the prototype for the modern snowmobile. While Eliason’s model became the most successful, it was not the first, and Northwoods residents experimented with all sorts of snow machines before settling on Eliason’s toboggan.
One of the earliest attempts at over-snow travel accompanied the bicycle craze of the 1890s. In Wisconsin people experimented with bicycles equipped with runners and gripping fins. Unsurprisingly, this did not last long. A few steam propelled sleighs appeared, and as early as 1895 a couple of inventors in Brule, Wisconsin, submitted a design for a propeller-sled. However, the most successful design that predated Eliason came out of New Hampshire in 1917.
