Abstract:
Provided is a system capable of appropriately setting the position of a work machine attachment (15) during a series of operations. The system is equipped with an automatic driving unit (53), a work upper limit position setting unit (61) and a work position change unit (63). The automatic driving unit (53) automatically drives the attachment (15) through multiple cycles of a series of operations which include an operation in which the control target position (16) of the tip end attachment (15d) moves along a target path (Pth). The work upper limit position setting unit (61) sets the work upper limit position (PWU). The work position change unit (63) changes the work position (PW) in the vertical direction according to the progress in the series of operations throughout multiple cycles thereof. After the work upper limit position (PWU) is set by the work upper limit position setting unit (61), the work position change unit (63) sets the work position during the series of operations in the cycle to be performed first to a position which is below the work upper limit position (PWU).
