Abstract
A floor-cleaning robot having a chassis for moving the floor-cleaning robot in a direction of travel over a surface to be cleaned, a cleaning implement, a control unit and first and second measuring devices for three-dimensional distance measurement. Each of the first and second measuring devices is configured to sense distance between the measuring device and a plurality of surface elements within a respective solid angle that is spanned from the measuring device. The first and second measuring devices are aligned in such a manner that the direction of travel runs through the first solid angle. The second solid angle is offset in relation to the first solid angle. The control unit is designed to generate and/or update a representation of the surface to be cleaned, on the basis of the distances from surface elements sensed by first and second measuring devices.

16. A floor-cleaning robot comprising:
-
a housing; a chassis with a drive for moving the floor-cleaning robot in a direction of travel over a surface to be cleaned, a cleaning implement is adapted to engage with the surface to be cleaned, a first measuring device for three-dimensional distance measurement within a first volume that is defined in part by a first solid angle, the first solid angle spanning from the first measuring device, the first measuring device being adapted to sense distances between the first measuring device and each of a plurality of first surface elements within the first solid angle, a second measuring device for three-dimensional distance measurement within a second volume that is defined in part by a second solid angle, the second solid angle spanning from the second measuring device, the second measuring device being adapted to sense distances between the second measuring device and each of a plurality of second surface elements within the second solid angle, and a control unit that is configured to generate and/or update a representation of the surface to be cleaned based on the distances from the first and second surface elements sensed by the first and second measuring devices, respectively, the control unit guiding the floor-cleaning robot over the surface to be cleaned based at least partly on the representation of the surface to be cleaned, wherein the first measuring device and the second measuring device are aligned in such a manner that the direction of travel runs through the first solid angle, and the second solid angle is offset in relation to the first solid angle. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
