Well here in central texas were lucky if it ever snows! but I hear in other parts of america it snows! so here is robot that can plow the snow from the sidewalks and driveways.
This could be a new way to train drive train team by having them build a new version in the summer that works better and drivers get tons of drive time. Also it could make an amazing fundraiser by charging people to clear there driveways.
Overall this is just something I thought someone might love to see!
