Abstract:
The present invention provides a technology that enables a portion serving as a reference for an attachment of a shovel to more appropriately move along a predetermined trajectory. A shovel 100 according to one embodiment of the present disclosure includes an attachment AT, an arm cylinder 8, and a boom cylinder 7 and a bucket cylinder 9, and is provided with: a plurality of actuators which drive the attachment AT; and a controller 30 which controls the operations of the boom cylinder 7 and/or the bucket cylinder 9 in line with the operation of the arm cylinder 8 so that a working portion of a bucket 6 follows a target trajectory. When a predetermined condition related to the operations of the boom cylinder 7 and/or the bucket cylinder 9 is satisfied, the controller 30 causes the boom cylinder 7 or the bucket cylinder 9 to operate so that the working portion of the bucket 6 follows the target trajectory.
