Abstract
A work machine includes: a work implement including a bucket; a bucket position obtaining unit that obtains a position of the bucket; a distance calculating unit that calculates a distance between the position of the bucket obtained by the bucket position obtaining unit and a design topography of an execution object; and a recording unit that records existing topography data corresponding to the position of the bucket, based on the distance calculated by the distance calculating unit.
Claims6
A work machine comprising:
- a work implement;
- a work implement position sensor that obtains a position of the work implement;
- an operation device provided to be able to receive an operation of operator;
- a controller;
- and
- a storage that records position data indicating the position of the work implement as existing topography data when the operation of the operator is received at the operation device;
- wherein the operation device includes one or more of a record button or a record switch,
- the controller calculates a distance between a designed topography of an execution object and a contour point that is closest to the designed topography of the construction target among a plurality of contour points of the execution object according to the position of the work implement acquired by the work implement position sensor, and
- the controller records position data indicating the position of the working machine of the closest contour point as the existing topography data when the operation of the operator is received at the one or more of the record button or the record switch of the operation device.
