Title:
GUIDE DEVICE FOR MOBILE ROBOT
Document Type and Number:
Japanese Patent JP2501010
Kind Code:
B2
Abstract:
PURPOSE: To safely and efficiently guide travel of a mobile robot based on environments obtained by plural different sensors.
CONSTITUTION: A surface form of a subject is interpreted by a sonar interpretation part 28 using sonar data as distance information to the subject. The surface form of the subject is interpreted by a stereo interpretation part 30 using stereo data of three-dimensional information based on video signals from a stereo camera 12. A hypothesis generating part 32 generates a hypothesis for the form of the subject using an interpretation without geometrically having inconsistency based on an interpretation obtained from sensors, and it time-serially collates sensor data corresponding to the surface form of the hypothesis with actual sensor data using a table deciding priority to be put between the sonar data and stereo camera data based on the hypothesis to test the hypothesis. For movement of a mobile robot, the mobile robot is guided for avoiding action referring to a traveling passage and in accordance with the hypothesis related to current environments.
