Buried object estimation system and excavator

Abstract

Technique for suitably estimating buried object in excavation target during excavation work performed by excavator is provided. Excavator includes: lower traveling body; upper turning body turnably provided on lower traveling body; attachment provided on upper turning body and configured to excavate excavation target; and controller including processor and memory, and configured to control movement of the attachment. Buried object estimation system includes information processing computer including processor and memory, and configured to, in order to estimate a probability of presence of a buried object in the excavation target, train a learning model for detecting the buried object by acquiring information related to excavation reaction force in excavation work performed by the attachment, and transmit the learning model to the controller. The controller estimates presence or absence of the buried object in the excavation target based on an excavation reaction force acquired in actual excavation work and the learning model.
