22nd International Symposium on Automation and Robotics in Construction ISARC 2005 – September 11-14, 2005, Ferrara (Italy)

Controlling of excavator’s arm is an important and basic task in autonomous research of hydraulic excavator at present, but the behavior of the excavator’s arm is dominated by the nonlinear dynamics of the hydraulic actuators. To find a feasible way to control excavator's arm and realize autonomous excavation, firstly, Full kinematic and dynamic models of the excavator arm, regarded as a planar manipulator with three degrees (boom, dipper and bucket) of freedom...
