Toward a robot that acquires logical recognition of space

For cooperation between robot and human being, robot should have logical recognition about space. For example, if a robot such as a housekeeping robot can recognize the arrangement structure of the furnitures and the concept of ``a room'', it will be useful information for asking the robot for work. Therefore, we aim for the robot to acquire the relationship between locations while moving. So, expecting that the robot gets the recognition that ``I have gotten out of the room'', we performed an initial stage experiment that a robot leaves the room using knowledge of the relationship between the entrance of the room and the door. This paper describes the insights obtained from this experiment.
