The invention relates to a
landmark dynamic configuration method and device for a
mobile robot searching unknown environments. A
landmark is the positioning and navigation indication of a
robot, no
landmark arranged in advance exists in the unknown environments, and natural characteristics are hard to extract from the environments for serving as the landmark. The scheme of the method for solving the problems is as follows; a
robot with a dynamic configuration landmark enters the unknown environments for searching, the landmark is independently and dynamically configured in an on-line way (realized by a vehicular putting device, seeing the abstract drawing) according to the positioning and drawing establishment requirements, and the configured landmark is used for finishing the positioning and environment drawing establishment of the
robot. A dynamic configuration landmark positioning device realizes the positioning of the robot on the basis of an ultrasonic distance-
measuring principle, realizes landmark identification on the basis of an exclusive identity method, and realizes data alternation on the basis of
radio frequency communication, thereby having the advantages of high precision, small volume, low
power consumption, and the like. The invention can be used for the fields of military affairs, antiterrorism,
extreme environment operation, and the like. which requires
intelligent equipment to carry out independent operation under the unknown environments.
