Get a quoteA hydraulic excavator can be considered a large, four degree-of-freedom manipulator mounted on a tracked base. The bucket at the end of the manipulator is used for digging and depositing the excavated material into the trucks. A core technology required for automation is the motion plan-ning of the excavator's manipulator.
