We tend to avoid scooping up sushi whenever there's no chef in sight -- at, say, a grocery store, or a gas station -- but we've always assumed there was a human cranking out maki somewhere behind the scenes. If Suzumo's SushiBot makes it to the production line, that may no longer be the case. The compact machine doesn't exude beauty in the traditional sense, but what it lacks in elegance it easily makes up with efficiency. The contraption can plop down rice clumps for nigiri at a rate of 3,600 per hour, and -- perhaps even more impressively -- it can construct one complete sushi roll every 12 seconds, with some human assistance to place fish on the rice. We tend to like the imperfect handmade feel of the traditional Japanese delight, and we're surely not alone, so don't expect to see one these pop up in your neighborhood Asian eatery. Supermarkets, hospitals and airline caterers may be more likely to pick up a SushiBot, however. Hungry? Intrigued? Roll past the break to see how it works.
