Title:
AUTONOMOUS MOVEMENT METHOD AND AUTONOMOUS MOBILE BODY
Document Type and Number:
WIPO Patent Application WO/2011/061924
Kind Code:
A1
Abstract:
Disclosed is an autonomous movement method capable of preventing a robot from erroneous recognizing a self position even when performing autonomous movement using environmental magnetism outdoors. The autonomous movement method is a method for autonomously moving a mobile body by comparing environmental magnetism data acquired by prior measurement of magnetism generated along a movement path traversed by a mobile body (100) with measured magnetism detected by measuring the magnetism generated along the movement path when the mobile body (100) follows the movement path in movement; wherein the method is provided with a step (a) for detecting a first measured magnetism and a second measured magnetism at different positions atop the mobile body (100); and a step (b) for autonomously moving the mobile body (100) on the basis of the second measured magnetism that is detected by a magnetic sensor (103) that is not affected by unpredicted magnetism (G) not included in the environmental magnetism data, and the environmental magnetism data.
