An autonomous crawler excavator for hazardous environments

Abstract

Abstract As part of ROBDEKON, a 24-ton crawler excavator was equipped with sensors and a digital actuation interface as a technology demonstrator which features autonomy capabilities. The system architecture includes algorithms for localization, perception, mapping, planning, and control. The system is capable of tasks like autonomous driving to a target location, excavation of a predefined area to a given depth, and autonomous loading of an autonomously approaching transport vehicle. To ensure safety, collision avoidance based on 360° perception is always active during autonomous operation. This article presents the concept and implementation of the excavator’s autonomy functionality.
