The unstructured construction site with a complex and changeable environment brings challenges to human–machine interaction. In this study, the earthwork digital twin (DT) is proposed to realize accurate and real‐time perception, which can support the teleoperation of an automated bulldozer. The overall framework includes anterior‐time DT, real‐tim...

The autonomous control and communication are the key technologies for unmanned earthwork machinery, and vehicle control terminals with compatibility are essential. This research develops a smart terminal-box (T-box) compatible with various types of unmanned earthwork machinery (including bulldozers, graders, and rollers). The data encoding and deco...

Unstructured and variable construction sites bring challenges that can be addressed with the adoption of the flexible earthwork scheduling problem (FESP), which requires consideration of mechanical parameters, automated construction techniques, and site constraints. This paper describes the use of the non-dominated sorting genetic algorithm (NSGA-I...

Bulldozers are indispensable heavy equipment for earthwork construction, and improving the intelligence level of bulldozers is of great significance to the construction industry. An efficient autonomous construction of earthmoving machinery requires imitating and learning the expert knowledge of operators under complex environments, and imitation f...

A changeable and unstructured construction site presents challenges for the operating requirements of autonomous earthmoving machinery. We implement decision planning based on an end-to-end deep learning method, which fills the gap in the research related to the intelligent construction of autonomous bulldozers. Our proposed method can acquire rele...

Unmanned construction machineries have been developed to meet the precise construction design requirements and improve productivity. As indispensable equipment for the earthwork process, bulldozers with unmanned design and automatic operation are of considerable importance. This paper presents an unmanned bulldozer for automatic construction, and t...
