Abstract
A measurement instrument, i.e. a mobile body, measures distances between a current position of the mobile body and obstacles in the environment of the mobile body by: a) taking at least N measurements of distances between the mobile body and the obstacles, by consecutive angular steps of A/N (A is a predetermined angular sector), and combining the distances with the respective angular steps in order to establish map data; b) moving the mobile body and repeating step a) for a new current position of the mobile body; and c) simultaneously determining, according to the distances measured for each angular step of the current position of step b) and the preceding position of step a), the current position of the mobile body in step b) on the map relative to the initial position thereof in step a), and new data of the map.
