BACKGROUND

1. Field of the Invention

The present invention relates to a method of performing cloud simultaneous localization and mapping (SLAM) in real time and a robot and a cloud server for implementing the same.

2. Discussion of Related Art

Robots may be placed to provide information or convenience to people in spaces where personal and material exchanges are actively conducted such as a large-scale mart store, a department store, an airport, and a golf course.

The robots may include a guide robot, a security robot, a cleaning robot, and the like, and these various robots move while checking their locations in the space.

In order for robots to check their locations, avoid obstacles, and move around, the robots have to keep spatial information and information regarding the current locations and routes the robots have previously traveled.

Also, in this process, the robots may ascertain their current locations by storing information about the physical layout of the surrounding space and comparing the information to map information that has been stored.

However, in order for a robot to accurately determine the current location, there is a need for the precision of information about the layout or space for the surrounding environments.

As the precision of information increases, the size of data to be processed increases, and thus the computing power of a processor necessary to process the data also requires high performance.

This specification proposes a solution for a robot to process high-precision information in operative association with a cloud server and perform simultaneous localization and mapping (SLAM).
