This invention relates to a kind of locomotive robot map built system and built method. The system includes wireless sensor network node and locomotive robot, wireless sensor network node integrated processing and locating cell, USB mouthpiece, power management module, temperature control module, and user interface; Locomotive robot is furnished with wireless locating and sends-receive module, and map built server. The process are: dispense wireless sensor network node to monitor area and form wireless sensor network, according to wireless sensor network nodal data to construct Delaunay triangular facet film, and estimate each fiducially mark section corresponding data; adopt threshold value comparative method to built singleness information map, then process logical operation and fusion of much sheet singleness information map to gain map based on multiunit message. This invention real-time build plat map in unstructured decisions and dynamic environment, or used in battleground, outer star, outdoors and so on specific environment for building global map.
