A method creates an environment map of a surrounding region for the operation of a mobile, self-moving appliance, in particular a floor cleaning appliance such as a vacuum cleaning and/or sweeping and/or mopping robot. The method includes: detecting the region around the appliance with at least one first sensor, to create a first horizontal plane of the environment map; detecting the region around the appliance with at least one second sensor, to create a second horizontal plane of the environment map, which is different from the first horizontal plane; and planning a movement path of the appliance based on the first and second planes of the environment map, in order in particular to achieve the maximum floor processing possible in the surrounding region.

The present disclosure discloses a mobile robot positioning method and system based on wireless ranging sensors, and a chip. The mobile robot positioning method adopts a manner of controlling a mobile robot to traverse two target positions successively to acquire a distance between the mobile robot at each traversed position and a fixed positioning base station, rather than calculate distances between the robot at the same position and different base stations, such that the trouble of arranging a plurality of base stations in a positioning area is reduced.
