Abstract

The invention belongs to the technical field of robot navigation and relates to a service robot autonomous navigation method based on raster maps. According to the method, the information of the environment where a robot is located is acquired in real time through 2D laser radar, environment feature extraction is conducted, raster map establishment is conducted according to the acquired information by means of the SLAM technique, autonomous positioning is conducted on the robot in real time at the same time, path planning is conducted on the robot according to navigation task requirements on this basis, and then tracking control is conducted according to the planned path to enable the robot to accomplish the navigation task. Compared with the prior art, the method has the advantages that three key techniques in navigation are improved so that the method can meet actual requirements of service robot navigation better, and then the optimal feasible scheme is obtained; environment information is processed in real time to generate dynamic maps, and then autonomous navigation is achieved effectively, and navigation accuracy and efficiency are improved greatly.

Description

technical field [0001] The invention belongs to the technical field of robots and navigation, and relates to an autonomous navigation method for a service robot based on a grid map. Background technique [0002] Autonomous mobile robot is an important branch in the field of robot research, and it has been widely used in many fields such as military, civilian, and scientific research. In recent years, with the development of computer, sensor and network technology, the focus of research has shifted from fixed manipulators and manipulators in structured environments to autonomous mobile robots in unstructured unknown environments. The traditional methods of modeling the space environment of the manipulator and teaching the movement can no longer meet the new tasks faced by autonomous mobile robots. Autonomous navigation technology is the core of mobile robot research and the key technology to realize autonomous movement, mainly including autonomous positioning, path planning,...
