Robots are being designed to do everything from fighting fires on navy ships to watching over young children, but Japanese firm Suzumo has already mastered something much more useful — the robot sushi chef. The company actually built its first sushi making machine back in 1981, and today it offers a whole range of what it calls "sushi robots." These machines can make large amounts of sushi while attempting to mimic the quality of experienced chefs. And though the quality part is up for debate, the bots certainly can pump out a lot of sushi — the SVC-ATX, for instance, can put together 960 thin norimaki rolls an hour. Unfortunately, Suzumo's robots aren't completely autonomous; while they can assemble and roll the sushi themselves, a human is still required to feed them the ingredients.
