Abstract: PURPOSE: A method and a system for estimating the force of a bucket of an excavator are provided to reduce the cost for estimation by employing an inexpensive pressure sensor. CONSTITUTION: A method for estimating the force of a bucket of an excavator is as follows. A first pressure, the piston head-side chamber pressure of a hydraulic cylinder, and a second pressure, the piston rod-side chamber pressure of the hydraulic cylinder, are received from a pressure sensor which is installed in the hydraulic cylinder(300). The force of the hydraulic cylinder is measured using the difference between the first pressure and the second pressure(302). The measured force is converted into the torque of a link axis(306). The force applied to a bucket is estimated from the torque(308).
