A contemporary technique used to control tele-operated excavators based on naked-eye feedback exhibited inferior performance compared to those using camera-based visual feedback due to the effect of operator position. To improve the quality of visual feedback, this report presents a novel observation method with regard to the portable control of a tele-operated excavator. First, the former replaced...
Operating excavator on the risk surroundings is not safe for human to control on site. Consequently, automatic excavator called Field Robot has been researched to protect the workers from the hazardous environments. The remote excavation system is required to perform in such environments. This paper presents the study on remote control system for the Field Robot and augmented reality vision for user...

Consequently, automatic excavator called Field Robot has been researched to protect the workers from the hazardous environments. The remote excavation system is required to perform in such environments. This paper presents the study on remote control system for the Field Robot and intuitive vision system for user...
Hydraulic excavators are among the most versatile earthmoving equipment: these machines are used in civil engineering, hydraulic engineering, grading and landscaping, pipeline construction and mining. Especially, in flattening task, the excavator operator actuates the machine controls (joysticks, pedals and switches) in an organized form to achieve the desired straight motion. The actuation of these...
Excavator is used in general versatile construction operations such as digging, carrying loads, grounding and dumping loads. However, it is not safe for the worker to operate the excavator on the risk environments. Consequently, excavator's unmanned research focused on a few universities and companies are being studied. One of the most important things for researching automation of excavator is control...
The hydraulic excavator of field robot has been used in various fields of construction, such as digging, carrying loads, grounding and dumping loads. However, operating excavators in the hazard environment such as earthquake, nuclear decomposition etc is not suitable for human to operate on site. Therefore, a number of the skilled operator is gradually reduced by the dangerous working environment...
Field robot represented by excavator can be applied for various working in manufacturing, construction, agriculture etc. Because of the flexibility of its multi-joint mechanism and the high power of hydraulic actuators. Since the excavator operates in the hazardous working circumstance, operators exposed in harmful environment. Therefore, automation system has been investigated to protect from the...
