As a safety measure for inspection work, Blue Innovation Co., Ltd. announced on April 16 that the indoor inspection spherical drone "ELIOS 3" has been introduced to Shimizu Corporation (hereinafter referred to as Shimizu Corporation). At Shimizu Corporation's construction sites, inspections before the completion of construction and post-construction inspection work are carried out. However, the locations for these tasks include underground pits that pose a risk of oxygen deficiency and high places that require scaffolding. As a safety measure for these hazardous inspection tasks, Shimizu Corporation has been focusing on drones and has been considering in-house development. However, in underground pits where GNSS and compasses do not reach, even professional drone pilots could not achieve stable flight, making inspections with drones difficult. The "ELIOS 3" is a drone capable of flying in indoor environments where GNSS and compasses do not function. Shimizu Corporation conducted verification of the drone's introduction in underground pits, inside buildings under construction, and within tunnels. As a result, they confirmed safety and outcomes equivalent to visual inspections, leading to the decision to implement it. After the introduction, it has been reported that not only has safety improved, but it has also contributed to increased work efficiency and cost reduction.
