Reshaping the Mining Industry

The Autonomous Haulage System (AHS) is a comprehensive fleet management system for mines. The autonomous dump truck, jointly developed by Komatsu Ltd., Komatsu America Corp. and Modular Mining Systems, Inc, is centrally controlled through a wireless network that integrates on-board vehicle controllers, high precision global positioning, and obstacle detection and avoidance systems. The system has full supervisory logic that utilizes complex data fusion to control the dump truck to safely operate through a load, haul and dump cycle and allow integration with other mine vehicles such as light vehicles, dozers, loaders, graders.


  • Increased safety on mine sites
  • Reduction of incidents (such as personnel fatigue)
  • Reduced number of drivers working in remote and harsh conditions
  • Reduced operating costs – training, extended parts and tire life, exact compliance
  • Increased productivity and efficiency; maximized cost/ton
  • Reduced infrastructure costs required to support personnel
  • Favorable environmental benefits – reduced fuel consumption and emissions

Unrivaled Excellence: Modular and Komatsu

The synergy between the OEM and fleet management system must extend beyond an interface when you start assuming full control of a haul truck weighing over one million pounds in fleets where manned vehicles and driverless trucks coexist. Independent providers applying a “bolt on” solution without OEM knowledge could undermine the entire system, compromising equipment integrity and risking major liability issues. Komatsu uses a best-in-class approach, bringing together the proven 930-AT ultra-class haul truck with Modular's industry-leading haulage optimization and mine management systems to deliver a world-class autonomous solution.

  • Komatsu: Delivering World-Class Mining Equipment for Nearly a Century

Safe & Proven Record in Active Mines

In 1990, Komatsu entered the autonomous field, 6 years before commercial GPS was available.

In 2002, in support of its parent company, Komatsu, Modular patented its bi-directional autonomous haul truck concept.

In 2008, following the successful trial evaluation of five Komatsu 930E-AT driverless haul trucks, the Komatsu Autonomous Haulage System (AHS) was implemented commercially for the first time in the world. The system, which incorporates Modular technologies, was installed at a Chilean copper mine and marked the initial use of AHS vehicles in an open-pit environment.

Now, after more than a decade of in-pit operational experience, Komatsu and Modular have collaboratively moved nearly a billion tons of total surface material worldwide. Today, the Autonomous Haulage System serves as yet another example of Modular's proven ability to deliver high value and cutting edge solutions.

  • Over 25 years of continuous improvement
  • Over 10 years of in-pit operational experience, spanning 8 sites
  • Over 100 autonomous manufactured trucks
  • Over half a billion tons moved
