Liberaware IBIS2 Confined Space Inspection Drone

Liberaware is a Japanese developer of drones for inspecting and measuring narrow, dark and hazardous indoor spaces, founded on 22 August 2016 and headquartered in Chiba City. Listed on the Tokyo Stock Exchange Growth Market since July 2024, it runs drone, digital twin and contract development businesses with about 155 employees.

IBIS2 is a small inspection drone about 20 cm wide and 185 g, with dust-resistant motors, a camera tuned for dark spaces, flight control that stays stable after wall contact and an operating range of -5 to 60 C. It flies inside boilers, ducts, chimneys, furnaces, sewers, bridge girders, elevator shafts, ceilings and tanks where people cannot safely enter. Liberaware offers it for sale or rental and as an inspection service, and converts video into 3D point clouds and BIM models. IBIS2-C adds distance and damage measurement for pipes, and Torinos provides automated patrol cameras for plants and utility tunnels.

• Compact airframe: about 20 cm wide and 185 g for spaces people cannot enter.
• Dust-resistant motors: flies in dusty boilers, ducts and attics.
• Low-light camera: clear video in dark interiors.
• Contact-stable flight: control that recovers after touching walls.
• IBIS2-C: distance and damage measurement with real-time position tracking in pipes.
• DX services: point cloud, BIM and image analysis from drone data.

• Thermal power plants inspecting boiler interiors and flue ducts during scheduled outages.
• Urban drainage companies checking sewer and culvert conditions without man entry.
• Building and railway operators surveying ceiling voids, elevator shafts and bridge girders at night.

• Inspects confined interiors without scaffolding or human entry, including dusty areas where asbestos may be present.
• Light 185 g airframe limits the risk of damaging equipment if it falls.
• Shortens shutdown and closure windows: about 40% fewer night-time closure work hours in a bridge inspection case with NEXCO Engineering Hokkaido.
• Video can be turned into point clouds and BIM for maintenance planning.

Ageing industrial plants and infrastructure, combined with labour shortages, are pushing owners to inspect boilers, ducts, sewers and tunnels without sending people into confined spaces. Small indoor drones and digital twins are becoming standard tools for this work in Japan. Thermal power plants, cement and steel mills in Vietnam face similar safety and downtime pressures during planned shutdowns.
