Abstract

We propose a method for the efficient scooping of sediment by a wheel loader. We performed experiments to verify the effectiveness of the proposed method. First, in order to calculate the energy required for the scooping operation, we derived a model of the reaction force that is generated on the bucket. We verified the validity of the model by experiments. We then used the reaction force model to determine the optimal trajectory for the bucket. A mechanical simulator was used to verify the trajectory. Although experimental results showed the unexpected effects of sediment that settled inside the bucket, we obtained results that reflect theoretical values.
