The digital box controls all functions of the milling and sewer rehab robots as well as the cameras, and supplies all components with power. The Schwalm robot electronics were intentionally positioned at the rear. In the event of electronic faults, these can be checked or replaced easily without having to open up the entire robot. Unnecessary opening processes which reduce the seal of the carriage against water penetration can thus be avoided.
A further advantage of the Schwalm digital box is that this is compatible with both milling and sewer rehab robots.
