It is important to inspect and recovery the crack of the large-scale construction. However, it is inefficient in time and cost aspects for managers to climb the top of construction and to check the crack in every day. To solve this problem, we made the construction inspection robot (CIR) which inspects the crack instead of them. CIRs are sent to the suspicious spots which may have cracks and then they send the real-time images to the server computer. We've constructed the whole simulation system which are applied for the DEVS (Discrete EVent system Specification) formalism about the inspection environment of structure safety. As a simulation result, managers may send CIRs to the suspicious spots and check there. Finally managers could previously prevent the risk from the more dangerous events and safely manage the construction.
