Fall-protected autonomous travel system with boundary markers

摘要

A fall-protected autonomous travel system with boundary markers is disclosed. The boundary markers are arranged in a travel area of a mobile unit. The mobile unit contains a spatial scanning device with a sensing range in which the travel area of the mobile unit is scanned in the mobile unit's direction of travel. A program-controlled control device brings the mobile unit to a stop if the spatial scanning device senses at least one boundary marker in a first safety sub-range of the sensing range.
