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...
Hydraulic excavators are the representative of field robot and has been used in various fields of construction. Since the excavator operates in the hazardous working circumstance, operators of excavator exposed in harmful environment. Therefore, automation and remote control system have been investigated to protect from the hazardous working environment. In this paper, a hydraulic simulation program...
In this paper, an overload detecting algorithm for an excavator is presented. The proposed overload detecting algorithm is based on the time series analysis especially moving window method and correlation function. The main purpose of this paper is to prevent damage or crack from the fatigue in advance. In this paper 16 channel sensor data are considered and each sensor frequency is 100 Hz and sampling...
