| In present the unmanned construction system technology is adapted on initial operation against of the disaster occasion. For instance it has been used in Unzen. It depends on the scale and site situation of disaster which system should be applied to. A lot of remote control technology of operating construction machinery has been developed as that technology. Underwater bulldozer was developed in 1968, which is a start of the technology. Recently the remote control technology has been applied to restoration works for digging、loading and transportation after the eruption of Unzen. The present study verifies it concerning the operativeness of a remote system that offers the site information by the monitor and operates it. In the research, it has aimed at the operativeness improvement, the working efficiency improvement, and the tiredness decrease. Arrangement and the operation of the monitor are researched now. Moreover, we do the examination for the system improvement in the future. In this report、the operation experimentation of 'Remote control in the site 'and' Remote control systems that displayed the monitor and operated the site information'（two kinds of systems）was done. And, it is the one that the ability and the behavior pattern that recognized the space of the operator were verified. |
