How does the GRANUBOT work? After the height is set at the laser, the signal is transmitted to the control unit of the device, which identifies and corrects even the smallest differences in height. In this way, the lower edge of the peeling sword is permanently maintained at exactly the same level. Thanks to the flexible design it is not only possible to process a radius of action of 2.3 m around the device, but also the area under the device. Even areas with recesses, pillars and even heating pipes can be reached without loss of time and with the same precision. Planes with a slope can also be achieved without any difficulties by simply tilting the laser.
