Abstract
An automatic excavator for automatically excavating an excavation object and loading a loading object with the result excavation by utilizing a measuring instrument for determining the distance between the excavator and the excavation object and the loading object, an excavation object recognition system for recognizing a three-dimensional shape of the excavation object on the basis of an output from the measuring instrument, a target excavation position computing system for computing the target excavation position on the basis of the three-dimensional shape of the recognized excavation object, a target loading position computing system for computing a relative position of the loading object with respect to the excavator and a relative attitude of the excavator with respect to the loading object on the basis of an output from the measuring instrument, and computing a target loading position on the basis of the computed relative position, an automatic positioning system for automatically positioning the excavator in the computed target excavation position and the target loading position, an automatic excavation control system for automatically excavating the excavation object in the…
