This issue’s articles were selected for their technical level and innovation aspects, as well as according to their scope of coverage of the thematic areas of civil engineering and house building. Our intent is to cover different applications and technological aspects. The article by Ha, Santos, Nguyen, Rye, and DurrantWhyte describes the fully autonomous execution of excavation tasks in common construction, such as loading a truck or digging a trench. A 1.5-tonne hydraulic mini-exavator was used for field experimental work. The machine has been extensively modified to include a laser measurement system for scanning terrain. The dynamic model and implemented control strategy are presented.
