In order to automate the scooping, it is desirable that the resistive force acting on the bucket is obtained before the scooping is performed. The objective of this paper is to derive theoretically the resistive force acting on the bucket during scooping of piled rock fragments. First, the changes in shape of the rock pile due to the penetration of it by the bucket are modeled. Based on this model, the resistive force acting on the bucket is considered theoretically. Finally, it was confirmed that the calculated results obtained using the model agree well with the experimental ones.
