A robot that can be remotely controlled, comprising: layout storage means for storing a layout plan of a building; communication means for communicating with a remote terminal via a network; and travel control means for controlling travel of the robot to a designated position or room; wherein the robot has self-position identification means for identifying its own current position and direction in the building; the communication means is operable to receive the coordinates of a destination designated in the layout plan from the remote terminal; the robot is operable to produce a route to the destination; the robot is operable, using the travel control means, to travel towards the destination and to determine whether it arrives at the destination; characterised in that: the communication means is operable to receive data from the remote terminal indicating a picture size that can be displayed on the remote terminal; the robot is operable to convert the size of the layout plan stored in its layout storage means into the picture size indicated in the data received from the remote terminal and to store the conversion scale; the communication means is operable to transmit the converted layout plan, containing the robot's identified own position, to the remote terminal; and the robot is operable to calculate the destination coordinates on a real scale using the stored conversion scale and the designated destination coordinates. layout storage means for storing a layout plan of a building; communication means for communicating with a remote terminal via a network; and travel control means for controlling travel of the robot to a designated position or room; wherein the robot has self-position identification means for identifying its own current position and direction in the building; the communication means is operable to receive the coordinates of a destination designated in the layout plan from the remote terminal; the robot is operable to produce a route to the destination; the robot is operable, using the travel control means, to travel towards the destination and to determine whether it arrives at the destination; characterised in that: the communication means is operable to receive data from the remote terminal indicating a picture size that can be displayed on the remote terminal; the robot is operable to convert the size of the layout plan stored in its layout storage means into the picture size indicated in the data received from the remote terminal and to store the conversion scale; the communication means is operable to transmit the converted layout plan, containing the robot's identified own position, to the remote terminal; and the robot is operable to calculate the destination coordinates on a real scale using the stored conversion scale and the designated destination coordinates. the communication means is operable to receive data from the remote terminal indicating a picture size that can be displayed on the remote terminal; the robot is operable to convert the size of the layout plan stored in its layout storage means into the picture size indicated in the data received from the remote terminal and to store the conversion scale; the communication means is operable to transmit the converted layout plan, containing the robot's identified own position, to the remote terminal; and the robot is operable to calculate the destination coordinates on a real scale using the stored conversion scale and the designated destination coordinates.
