Development of a Tele-Earthwork System

The tele-earthwork system we have developed is able to remotely control unmanned power shovels and unmanned crawler dump trucks, and a series of unmanned operations ranging from excavation to transportation. The results of our demonstration tests proved that the tele-earthwork system is capable of performing remote control operations at a point 1 kilometre or more away from construction sites, and its working efficiency through remote-control operation is approximately 0.4 lower than manned work.
