の間ツがあった。(C) Problems to be Solved by the Invention However, even if the propulsion course is determined using the above method, there are obstacles such as stones and wood buried underground, so the underground penetrating machine will not be able to avoid these obstacles during propulsion. There are cases where the underground penetrating machine deviates from the planned course by hitting an obstacle, and there is no way to detect if the underground penetrating machine deviates from the planned course, and the underground penetrating machine may come out of an unexpected place. There were some delays, such as when the metal went too deep underground and could not be recovered.
