SURROUNDINGS MAPPING APPARATUS CAPABLE OF APPLYING QUICKLY CHANGED SURROUNDINGS INFORMATION IN MOBILE ROBOT AND METHOD THEREOF
First Claim
1. An apparatus for building an environment map of a mobile apparatus comprising:
- a traveling unit for traveling a mobile apparatus in accordance with an inputted command;
a distance measuring unit for measuring a distance between the mobile apparatus unit and a moving object located in the surroundings of the mobile apparatus;
an environment map-building unit for building an environment map based on a distance value measured by the distance measuring unit;
a moving object detecting unit for detecting a moving object moved after building the environment map by comparing a distance between the mobile apparatus and the moving object in the building environment map with the distance value newly measure by the distance measuring unit; and
a controlling unit for selectively applying changed environment information containing the moving object to the building environment map when the moving object is detected to update the environment map in accordance with the inputted command.

Abstract
A method of responding to environmental change to build an environment map of a mobile apparatus and an apparatus thereof are disclosed. The apparatus includes a traveling unit traveling a mobile apparatus according to a command, a distance measuring unit measuring a distance from the mobile apparatus to a moving object, an environment map-generating unit generating an environment map based on a measured distance, a moving object detecting unit detecting the moving object moved after generating the environment map by comparing a distance from the mobile apparatus to the moving object with the newly measured distance, and a controlling unit updating the environment map according to the command by selectively applying changed environment information containing the moving object to the built environment map when the moving object is detected. Thus, the changed environmental information can be rapidly and precisely applied to build the environment map.
