Abstract

Embodiments of the invention disclose a mobile robot navigation system and method. The system comprises a mobile robot, a navigation two-dimensional code and a navigation light band; the mobile robotcomprises an industrial personal computer, a high-speed camera and a photoelectric sensor; the navigation light band is laid according to a preset line; the navigation two-dimensional code is fixedlyarranged in a preset position of the navigation light band; the high-speed camera is installed at the bottom of the mobile robot and used for acquiring navigation two-dimensional code information; thephotoelectric sensor is installed at the front end of the bottom of the mobile robot and is used for emitting a light signal to the navigation light band and receiving a light signal reflected by thenavigation light band; the high-speed camera and the photoelectric sensor are connected with the industrial personal computer; and the industrial personal computer acquires signals sent by the high-speed camera and the photoelectric sensor, and adjusts motion postures of the mobile robot according to the signals. Therefore, accurate navigation of the mobile robot is realized.

Description

technical field [0001] The invention relates to the technical field of robot navigation, in particular to a mobile robot navigation system and navigation method. Background technique [0002] Autonomous navigation refers to the mobile robot perceives the environment and its own state through sensors, and realizes the goal-oriented autonomous movement in the environment with obstacles. In the research of related technologies of mobile robots, autonomous navigation technology is a key link to reflect its automation and intelligence. [0003] Traditional photoelectric line inspection mobile robots usually implement autonomous navigation by laying reflective navigation belts and using sensors to detect reflected light. However, it is still impossible to accurately obtain the global position and heading information of mobile robots only by laying reflective navigation belts, and it is not suitable for scene navigation under complex path planning. From the perspective of enginee...
