Abstract
A boring machine comprises a forward section, a rear section, an articulation point, a parallel link mechanism, an input component, an articulation point position computer, and a jack controller. The parallel link mechanism includes a plurality of thrust jacks that change the position of the forward section with respect to the rear section. The articulation point position computer computes the position of the articulation point on the basis of the control inputs received by the input component, and the positions of the center line and center point of the rear section and the center point of the forward section. The jack controller controls the stroke amounts of the thrust jacks to produce movement corresponding to a curve generated from the positions of the center point of the rear section, the articulation point, and the center point of the forward section.
