How can a small battery powered device replace a powerful gas powered snow thrower?
It is a known fact that, pushing is much more efficient than throwing when it comes to light to moderate snow. However when snow accumulates to a certain height, this is no longer practical, and requires to throw it further. Snow throwers throw up snow about 6~10 feet up, wasting lot of energy. I-Shovel efficiently pushes snow when its still fresh and lite in relatively short cycles. The computer algorithm controlling the robot closely mimics the shoveling process a human usually does with a manual shovel.
