Abstract: Provided is a work machine (1) capable of being operated automatically with reduced discomfort to workers. The work machine (1) includes a controller. The controller sets target trajectory information including a plurality of target points on a target path (71B) of a control target part and an inter-target-point time and makes an upper turning body (22) and a work device (30) perform a target motion of moving the control target part in accordance with the target path information. When judging work including the target motion to reach a predetermined stage, the controller shifts at least one of the start point and the terminal point of the next target motion and corrects the inter-target-point time based on the change from a previous movement amount to a new movement amount. The previous movement amount is the movement amount of the control target part from the start point to the terminal point before the shift, and the new movement amount is the movement amount of the control target part from the start point to the terminal point after the shift.

Abstract: Provided is a work machine (1) capable of automatic with reduced burden on a worker. The work machine (1) includes a controller that controls driving of an upper turning body (22) and a work device (30) to make the upper turning body (22) and the work device (30) perform a designated motion. The controller revises the designated motion, when a restriction target part of the work device (30) will be protruded beyond a preset allowable area during the designated motion, to keep the restriction target part from being protruded beyond the allowable area.

Abstract: The invention is based on the idea of controlling the operations of the earthmoving machine (E) controllable by the operator (5) by using only one to four controllers (CO) and at least one displaying means for displaying controls selectable and controllable by the one to four controllers (CO). The selections and controls of the operations for controlling the earthmoving machine (E) may be transmitted to control unit (CU) both by wire and wirelessly. Thus, the one to four controllers (CO) are operable both attached and detached. Further, the control system (CS) is arranged to determine the location of the one to four controllers (CO) with respect to the earthmoving machine (E).
