That varies with haul and ramp distances." Mixed Fleets vs. Interoperability The Komatsu AHS can coexist with manned vehicles (mixed fleets) and oth- er makes and models (interoperability). "There are usually some issues with mixed fleets around the dump zone," Cook said. "When the manned truck makes a mistake, the autonomous truck will view that as an obstacle. Most of the dumps are large and they can be easily divided into manned and autonomous op- erations. But, certainly around the crush- er and on the haul roads, we can operate manned and autonomous trucks at the same time." As far as interoperability, Cook said that, when it comes to AHS, Modular is Komatsu's autonomous systems are positioned at the midpoint of the operating spectrum.
