Roofus is a radio-controlled snow plow designed to remove snow from roofs of buildings (thus, the name Roof-us) where it would be particularly risky for a human to do so.  Personally, I would like to employ it for my driveway during the winter and sit back with a warm coffee, directing it’s efforts.

Roofus also has additional attachments for use in seasons other than the winter, converting it to a remote-controlled lawnmower, or cleaning machine.

Roofus ranked in the top twenty among 300 entries at the International Design Competition 2007/JDF in Osaka.
