A design of the tele-operation control system for liquid container transfer by an overhead traveling crane

This research is suggested a design method a tele-operation control for liquid container transfer by an overhead crane system that allows the operator to control the speed of the overhead crane freely and to feel the swing of the rod instinctively through the reaction force. In remote control, the information of the distant place is important. Particularly, feeling the reaction force for operation is important like watching the rod's movement with cameras. The proposed system in this research can be used via the internet and can be controlled from everywhere. For example, operating in a place such as the steel and the casting factory where is bad work environment due to a high temperature and mine dust, this tele-control system using the internet as its communication line can be useful, since it allows the operator to control the crane from a safer and good environment place. The usefulness of proposed system is demonstrated by an experiment.
