A remotely controlled robot comprises a unit storing the layout plan of a
building, a unit receiving a position remotely designated in the layout
plan from a remote location and a unit controlling the travel of the
robot to the designated position. A self-position identification method
is implemented by a robot with a camera whose shooting direction can be
changed. The robot takes in advance a panoramic picture of a room where
the robot may travel, generates a reference picture by extracting a
plurality of block pictures from the panoramic picture and identifies a
room where the robot is located, by applying correlation and DP matching,
using both a picture taken in the room where the robot is located and the
reference picture.
