Construction machinery and robots are essential equipment for major infrastructure. The
application of deep learning technology can improve the construction quality and alleviate …

Excavators are widely used for material handling applications in unstructured environments,
including mining and construction. Operating excavators in a real-world environment can be …

The challenging characteristics of earthwork environments—complex, unstructured, and
constantly evolving—pose significant challenges for the path planning of automated …

Single-objective optimal trajectory cannot adapt to the complex requirements of excavator
construction. A comprehensive optimal trajectory planning method is proposed to optimize …

In this letter, we present an excavation controller for a full-sized hydraulic excavator that can
adapt online to different soil characteristics. Soil properties are hard to predict and can vary …

Current digging trajectory planning methods for excavator arms are limited to a single
digging cycle, which does not meet the continuous excavation demands of the task. To …

As modern large-capacity excavators, cable shovels provide payload capacities of more
than 100-tons per scoop. The presence of a high dynamic payload combined with the self …

This paper proposes a trajectory planning and control method for heavy-duty manipulators
based on inclination-displacement mapping. In this method, inclination sensors are …

Excavation of irregular rigid objects in clutter, such as fragmented rocks and wood blocks, is
very challenging due to their complex interaction dynamics and highly variable geometries …

Automation of excavation tasks requires real-time trajectory planning satisfying various
constraints. To guarantee both constraint feasibility and real-time trajectory re-plannability …
