This initiative was introduced on TV as the first of its kind in Tottori Prefecture. Recently, we were featured in the media regarding a demonstration experiment for inspecting water storage tanks using underwater drones. (Broadcast on April 23, 2026, BSS TV "Teleport San'in") In recent years, inspecting aging infrastructure and preventing accidents has become a significant challenge. By utilizing underwater drones, we can expect safer and more efficient inspections in areas that are difficult for people to access or where we want to check without draining water. I believe that the use of underwater drones will become increasingly important in the fields of investigation, inspection, disaster prevention, and maintenance management. ▼ Here is the broadcast content 【Channel Teleport San'in】 Repeated "road collapses"... The cause is broken water pipes. To prevent this, we are conducting a demonstration experiment on inspecting water storage tanks with "underwater drones." What are the benefits? https://youtu.be/CI6aY44Xs9M?si=xZjH2KG4_UrzAfJY
