the dream for the future is to have a robot in every household, but for this to become reality it is imperative that we create an environment that is friendly to robots. It is extremely difficult to make robots with a built-in knowledge or recognition of every item in the house. But if we built, say, refrigerators with IC (integrated circuit) tags embedded in them, a household robot could then communicate with the refrigerator and the refrigerator could identify itself to the robot as a refrigerator. The robot would thus be able to recognize household objects with ease. The idea of embedding IC tags in household appliances is basic to the ubiquitous society of the future, in which all devices will be connected by ubiquitous networks. Social system such as the fusion of robotics with the ubiquitous society will be necessary if we are to create an environment in which robots can comfortably function. the promotion of robot technology one of the pillars of its policies for technology, and it has started to construct various different frameworks of this type.
