PROBLEM TO BE SOLVED: To provide a robot capable of highly accurately measuring the distance from the object of measurement, which is nearly parallel with the line between visual axes. SOLUTION: The robot carrying imaging devices at its head section is provided with a neck section connected to a body section, the right imaging device and the left imaging device for imaging the outside world, an imaging device base table on which both of the imaging devices are installed, an inclination device for inclining the imaging devices to the neck section, and an image processing section for processing the image information obtained from both imaging devices and calculating the distance from the object of the measurement to both of the imaging devices. Taking the straight line comprising the centers of the imaging devices liked as a line between visual axes, if the object of the measuring is judged nearly parallel with the line between visual axes, the imaging device base table is inclined by operating the inclination device, and the image is picked up again, and the distances between the object of the measurement and the imaging devices are calculated based on the image information imaged again.
