The 460 articulated dump truck marks Deere’s initial foray into autonomous construction equipment, with a focus on the controlled settings of quarries. Officials from Deere indicate that these machines are typically operated by less experienced individuals within a quarry. By removing the need for an operator in the ADT, a quarry can utilize its skilled operators on tasks involving excavators and loaders.
Productivity in quarries relies heavily on the efficient transport of rocks from the extraction site to the crusher. ADTs are responsible for ferrying materials between the stationary excavator or loader and the stationary crusher. Any disruptions along this route can negatively impact overall productivity. Mike Vorster highlights the implications of downtime, noting that the failure of a single truck to operate reliably can have significant consequences.
Given the essential demand for reliability across the numerous ADTs in quarry operations, Deere decided to implement autonomy in this machine.
How Does the Autonomous Deere ADT Operate?
The operation of the autonomous ADT begins with the technology and software known as the “tech stack,” which Deere has developed for its agricultural equipment, as explained by Maya Sripadam, senior product manager for autonomy at Blue River. These essential on-board components—such as perception, navigation, and vehicle controls—are integrated with Deere’s Operation Center, also referred to as JDLink.
The system leverages Deere’s Starfire Guidance and StarLink for data transmission, creating a comprehensive control system, according to ADT specialist Kristen Camden. “We are removing the operator,” she noted, “therefore, all tasks related to steering, speed control, or dumping actions are enhanced with the appropriate ruggedized hardware.”
The site manager uploads a map of the quarry into the Operation Center, detailing the truck’s route along with the loading and dumping points, as stated by Sripadam. The manager establishes a “mission”—for instance, directing the truck to move from load point A to dump zone B while adhering to a designated path.
Autonomous operation can then commence through the Operations Center. Deere has indicated that this ADT is still in the development phase and has not provided a timeline for the release of retrofit hardware. Currently, the company is testing autonomous 460 P Tier ADTs in several quarries, with retrofits to be performed by authorized Deere dealers.
Kasey Kelly, an ADT specialist, mentioned, “Our autonomy strategy involves collaborating with John Deere dealers to ensure we’re helping customers find the most suitable equipment and solutions for their needs. This partnership also enables us to produce trucks at our factory that are ready for autonomy, allowing retrofitting capabilities for any truck.”
