Kind Code:
A1
Abstract:
This work machine comprises: a work device; an orientation detection device that detects orientation information pertaining to the work device; a hydraulic actuator that drives the work device; and a control device that generates operation plan information on the basis of task information, which is required for autonomous control and which is acquired from an external system, and that executes autonomous control of the hydraulic actuator on the basis of the operation plan information and the result of detection by the orientation detection device. The control device outputs the operation plan information to the external system. When an approval signal representing that the operation plan information is approved is not inputted from the external system, the control device does not execute the autonomous control; however, when the approval signal is inputted from the external system, the control device executes the autonomous control.
