摘要

PURPOSE: An intuitive control device for an excavator is provided to enhance the user-interface control ability of an excavator by mapping the movement of the bucket, boom and arm of the excavator to the control unit of a three-joint link similar to the arm and wrist articulation of a person. CONSTITUTION: An intuitive control device for an excavator comprises an movement control unit(20), pivoting control units(30,31) and an excavation control unit(11). The movement control unit controls the forward and backward movement and left and right turn of the excavator. The rotation control unit controls the left and right pivoting of a swing body. The excavation control unit controls the excavation operation of a boom, an arm and a bucket. The excavation control unit comprises a boom control unit(14), an arm control unit(13) and a bucket control unit(12). The boom control unit is rotatably connected to a fixed body, which is fixed to the swing body. The arm control unit is rotatably connected to the boom control unit.
