Research on Laser Navigation System of Mobile Robot Based on Robot Operating System

In order to verify the advancement of laser navigation and the convenience of robot operating system (ROS),the improved particle filter algorithm and A* path planning were proposed, which were respectively applied to map construction and path planning.And then the navigation test platform for mobile robots based on ROS platform was established,which had the advantage of low-cost and high-performance.The experimental platform was consists of two parts: upper computer and mobile robot.The mobile robot was controlled by upper computer.The mobile robot was equipped with industrial PC and laser sensor. The environmental information was collected through laser sensors ,which can provide data support for real-time positioning and map construction.The map building and autonomous navigation function package based on ROS was studied and constructed.And then the system was tested in the actual environment.The experimental results had showed that the function package constructed in this paper can be used in the laser navigation of robot. And the laser navigation system was feasible and had certain stability and reliability.
