Abstract
In a method of controlling construction machinery, a bucket of a working device is moved along a first excavation trajectory to perform an excavation operation on the ground of a work area. A digging force exerted on the bucket during the excavation operation is calculated. A new second excavation trajectory is generated based on the calculated digging force. The bucket is moved along the second excavation trajectory.
Claims14
A method of controlling construction machinery, the method comprising:
- moving a bucket of a working device along a first excavation trajectory to perform an excavation operation on the ground of a work area;
- measuring joint state values and cylinder pressure values of the working device during the excavation operation;
- calculating a digging force exerted on the bucket during the excavation operation using the measured joint state values and the measured cylinder pressure values;
- generating a second excavation trajectory based on the calculated digging force;
- and
- moving the bucket along the second excavation trajectory.
