Date Apr. 2, 1992.The invention relates to an automatic, self-contained machine for continuously mowing grass. The machine is powered by means of photovoltaic cells (10) and can be wheeled (15) or tracked. A device comprising a microcomputer programmed by an algorithm allows to search for spots where the grass must be cut and to detect the boundaries of the surface to be mown. The obstacles (92) are detected and passed around by analysis of relative movements of an upper panel (9) comprising the photovoltaic cells (10) and a lower frame (1).</p> |
