　　Back in the 1970s，the robots were coming for our boring manufacturing (生产) jobs.Now，they’re coming for our boring table service jobs.Korean company ITM Technology has developed the restaurant concept around a little robot that fulfills the role of a waiter.Robo Café avoids ordering errors，reduces staffing costs greatly for restaurant owners，and even brings the boss all the tips.

　　Japan is preparing for some very tough times ahead.When its aging population become too old to work，labor is going to be in severe shortage.So inventive technology departments are exploding with really fascinating ideas to take the pressure off when it hits.

　　To small café and restaurant owners，the solution might well look something like Robo Café，a restaurant designed to operate as efficiently as possible with the absolute minimum human workforce possible.The building needs to be designed with small horizontal (水平的) pathways leading from the kitchen to all the tables.A small team of waiter robots can then get around to every table in the house when they’re asked to come.Customers can either order orally，or touch a screen on the robot’s belly.When the kitchen has finished preparing the food，the robot brings it out to customers.
