Abstract
A work machine comprises a bucket attached to an end of a stick of the work machine as a work tool, a thumb pivotally coupled to the end of the stick, and processing circuitry. The processing circuitry is configured to determine a current task of the work machine among scooping an object by the bucket or grabbing the object by the bucket and the thumb, based on an angle of the bucket, and calculate payload with a parameter of a center of gravity position of the payload based on the determined current task.
Claims20
A work machine comprising:
- a bucket attached to an end of a stick of the work machine as a work tool;
- a thumb pivotally coupled to the end of the stick;
- and
- processing circuitry configured to
- determine a current task of the work machine among scooping an object by the bucket or grabbing the object by the bucket and the thumb, based on an angle of the bucket,
- calculate payload with a parameter of a center of gravity position of the payload based on the determined current task.
A method for controlling a work machine comprising:
- determining, using circuitry of the work machine, a current task of the work machine among scooping an object by a bucket or grabbing the object by the bucket and a thumb, based on an angle of the bucket, the bucket being attached to an end of a stick of the work machine as a work tool and the thumb being pivotally coupled to the end of the stick;
- calculating, using the circuitry of the work machine, payload with a parameter of a center of gravity position of the payload based on the determined current task;
- and
- outputting, using the circuitry of the work machine, on a display of the work machine, the calculated payload.
A non-transitory computer-readable storage medium including computer executable instructions, wherein the instructions, when executed by an information processing system of a work machine, cause the information processing system to perform a method, the method comprising:
- setting a mode for calculation of payload as an automatic mode;
- determine a current task of the work machine among scooping an object by a bucket or grabbing the object by the bucket and a thumb, based on an angle of the bucket, the bucket being attached to an end of a stick of the work machine as a work tool and the thumb being pivotally coupled to the end of the stick;
- and
- calculating payload with a parameter of a center of gravity position of the payload based on the determined current task.
