Title:

AUTONOMOUS MOBILE ROBOT, MAP BUILDING METHOD, AND MAP CALLING METHOD FOR COMBINED ROBOT

Document Type and Number:

WIPO Patent Application WO/2017/198207

Kind Code:

A1

Abstract:

An autonomous mobile robot (10), a map building method, and a map calling method for a combined robot. The autonomous mobile robot (10) comprises: a robot body (100) and a control center disposed on the body (100). The body (100) comprises a first distance sensor (101) that is horizontally disposed upwards and used for collecting two-dimensional map information and a second distance sensor (102) that is vertically disposed upwards and used for collecting space height information. When obtaining the two-dimensional map information on a working surface, the control center superposes the space height information to the two-dimensional map information, to obtain three-dimensional map information in a working area. By means of the method, the distance sensors are disposed on the autonomous mobile robot (10), and the space height information is superposed based on a generated two-dimensional map, to generate the three-dimensional map information. In a combined state, the autonomous mobile robot (10) calls the three-dimensional map and plans, based on the three-dimensional map, a moving path in the working area, so as to ensure smooth movement of the combined robot in a complex environment. The method is secure and efficient.
