Abstract
The electronic map becomes more and more popular due to its convenience and powerful functions. This paper aims to use map information to build a system for path planning and navigation of an intelligent robot. It can provide a basis for field autonomous identification of crop diseases and insect pests with the robot as the carrier. The open source Openlayers is used as a tool to link online maps. And Dijkstra algorithm is used to obtain the shortest path. And then it can simulate a robot moving along the path by creating a moving point. In addition, it could accomplish a series of fundamental operations of controlling movement and the display of route details. The feasibility of the functions is verified by experiments and it lays a solid foundation for subsequent work.
