Excavators are used for the rapid removal of soil and other materials in mines, quarries, and construction sites. The automation of these machines offers promise for increasing productivity and improving safety. To date, most research in this area has focussed on selected parts of the problem. In this paper, we present a system that completely automates the truck loading task. The excavator use...

The articulated dump truck is a widespread transport vehicle for narrow rough terrain environment. To achieve the autonomous driving in the underground tunnel, this article proposes a path following strategy -for articulated vehicle based on feedback linearization algorithm. First of all, the kinematic model of articulated vehicle, which reflects the relationship between the structure parameter...

This paper describes the theoretical development and experimental evaluation of a navigation system for an autonomous load, haul, and dump truck (LHD) based on the results obtained during extensive in-situ field trials. The particular contributions of the theoretical work are in designing the navigation system to be able to cope with vehicle slip in rough uneven terrain using information from i...

Children Are Good Observers Children learn from actively investigating the world around them. Coming upon a construction site, for instance, a fouryear-old will be curious about the activity. The adult with the child should take the time to stop, really look at what’s going on, and direct the child’s attention to the details. “Let’s watch and see what happens while that dump truck unloads dirt....
