Alat berat merupakan faktor penting di dalam proyek, terutama proyek-proyek konstruksi dengan skala yang besar. Dalam pekerjaan tanah meliputi galian diperlukan alat yaitu excavator. Pemilihan tentunya sangat berpengaruh pada tingkat efisiensi agar dapat menghemat waktu dan biaya. pengerjaan tugas akhir ini digunakan metode analisis komparatif. Dengan kata lain beberapa jenis pabrikan excavator...

Human operators of real-world co-robots, such as excavator, require extensive experience to skillfully handle these complicated machines in uncertain safetycritical environments. We consider the problem of human-robot collaborative learning and task execution, where efficient human-robot interaction is critical to safely and efficiently accomplish complex tasks in uncertain environments. Our co...

In this paper we describe the development of a three-dimensional (3D) imaging system for a 3500 tonne mining machine (dragline). Draglines are large walking cranes used for removing the dirt that covers a coal seam. Our group has been developing a dragline swing automation system since 1994. The system so far has been “blind” to its external environment. The work presented in this paper attempt...

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...

Hydraulic excavators are large, powerful machines which are often operated in high-production settings. Successful automation of excavators for mass excavation tasks require safeguarding algorithms which do not negatively impact productivity. We present a two-level sensor-based safeguarding approach which utilizes obstacle detection to prevent collisions and motion detection to halt operation w...

To more accurately predict the residual fatigue cycles and estimate service life of remanufactured excavator, models integrating corrected S-N curve, RFC algorithm, FEA model, mechanism dynamic model are established depending on real load spectra under experimental working conditions curve beam metal with welding process. Depending test data unidirectional stress history servo displacements maj...
