Summary:The invention provides a map construction method of a mobile robot, which comprises the following steps: S100, scanning an unknown area closest to a current position in a raster map, and planning a nearest path by using an A star algorithm; s200, scanning the surrounding environment through a sensor carried by the mobile robot, and recording the surrounding environment in a grid map; s300, detecting whether a closed boundary exists in the grid map or not, returning to the step S100 if the closed boundary is not detected, and executing the step S400 if the closed boundary is detected; and S400, detecting whether an unknown region exists in the closed boundary of the grid map, if the unknown region is detected, returning to the step S100, and if the unknown region is not detected, indicating that the map construction is completed. According to the method, the mobile robot accurately constructs the grid map in an unknown environment so as to guide the mobile robot to work in the environment; and meanwhile, the c
