【Abstract】 According to the structure of manipulator fixed on an excavator, dynamics analysis is run, and the dynamics equation is established. Control experiments on the manipulator tail end track are completed with PD feedback control method. Testing results show that the control system can made the manipulator to turn to the target angle accurately, the errors between the tested data and the target data of the manipulator tail end positions are less than 2.3cm in x axis and 1.6cm in y axis. The excavator and its manipulator can be applied in intelligent robot to dig the unexposed mine accurately for its precise track control.更多还原
