  "abstract": "A system for excavating a rock face using microwaves. The system may include a microwave generator, an articulable robotic arm with a plurality of rotatably connected rigid waveguide segments, an applicator attached to a distal end of the robotic arm, and a robotic control system. The system produces microwaves with the microwave generator and moves the robotic arm such that the applicator moves along the rock face as the microwaves exit the applicator to precondition the rock face for excavation. Various patterns of microwave treatment, and controls based on sensor feedback, may be implemented.",
