| | Abstract | | In recent years, drones, such as unmanned aerial vehicles (UAV) and unmanned ground vehicles (UGV), have been used, researched, and developed in various fields, and social expectations regarding them have increased. On the other hand, the problem of the shallow subsurface zone at a depth of several tens of meters below the ground has become apparent in fields such as infrastructure maintenance, environmental geology, and civil engineering. The necessity of shallow subsurface exploration in a wide area without digging the ground is increasing. Following these backgrounds, we had started the development of a new UGV electromagnetic (EM) exploration system (UGVEM system), such as a combination of the single-frequency multi-coil electromagnetic probe (CMD-EXPLORER) and UGV, with the Geological Survey of Japan, AIST. In general, we conducted fundamental experiments, including data acquisition using portable electromagnetic survey devices, by various methods such as "hand-held," "manual pulling," "manual steering," and "autonomous movement." This system succeeded in acquiring quality data for practical use. In addition, we evaluated the measurement data and method, and clarified future issues. |
