Abstract: A work machine includes an undercarriage, a swing body swingably supported by the undercarriage, and work equipment operably supported by the swing body. A control system controls the work machine. The control system includes a processor. The processor generates a design plane that is defined by a plane on a vehicle body coordinate system of which origin is a representative point of a swing body. The processor rotationally converts the design plane around the origin of the vehicle body coordinate system in association with a swing of the swing body. The processor specifies a position of the work equipment in the vehicle body coordinate system. The processor controls the work equipment based on the specified position of the work equipment and the design plane.

Abstract: A generation unit generates a virtual wall that is defined by a plane on a vehicle body coordinate system of which origin is a representative point of a swing body. A rotation conversion unit rotationally converts the virtual wall around the origin of the vehicle body coordinate system in association with a swing of the swing body. A position specifying unit specifies a position of an outer shell of a work machine in the vehicle body coordinate system. An intervention control unit controls the work machine such that the outer shell does not come into contact with the virtual wall.

Abstract: A work machine capable of saving works by an operator during traveling is provided. The work machine includes a vehicular main body including a traveling unit, a work implement attached to the vehicular main body, and a controller that automatically controls operations by the work implement. The controller cancels automatic control of operations by the work implement based on a traveling state of the traveling unit.
