In this December 2015 photo provided by Harvard University, junior Cesar Maeda explains a robotic snow blower to a group of officials at Harvard in Cambridge, Mass. Eighteen juniors representing several engineering disciplines spent the fall semester inventing a robotic remote-control rooftop snowblower, a super-heated icicle cutter and a freeze-resistant doormat. The inventions grew out of last winter’s record snowfall, which stretched campus maintenance department workers to their limit and forced a campus shutdown for the first time since the Blizzard of ‘78.
