Hello; As recorded in June 1995 in Popular Science Magazine, self-driving trucks were being developed for combat convoys, whereby only the lead truck would be driven by a human and the following trucks would rely on satellite, an inertial guidance system and ground-speed sensors. Komatsu made the earliest development in Autonomous Trucks testing a fleet of 5 Ultra Class truck of 290 Mt in Codelco Mine Radomiro Tomic in Chile in 2005 then in 2007 was installed the first working fleet in the mine Gabriela Mistral in Chile, also a Codelco property. Lockheed Martin with funding from the U.S. Army developed an autonomous truck convoying system that uses a lead truck operated by a human driver with a number of trucks following autonomously. Developed as part of the Army's Autonomous Mobility Applique System (AMAS), the system consists of an autonomous driving package that has been installed on more than nine types of vehicles and has completed more than 55,000 hours of driving at speeds up to 64 kilometres per hour (40 mph) as of 2014. As of 2017 the Army was planning to field 100–200 trucks as part of a rapid-fielding program. Caterpillar Inc. made early developments in 2013 with the Robotics Institute at Carnegie Mellon University to improve efficiency and reduce cost at various mining and construction sites. Companies such as Codelco Chilean State Mining Company, Suncor Energy, a Canadian energy company, and Rio Tinto Group were among the first to replace human-operated trucks with driverless commercial trucks run by computers.
