Liberaware Unveils the IBIS2 Chainage Drone for Sewer Inspections

On July 24, 2026, Liberaware Inc., headquartered in Chiba City, Japan, announced the launch of their advanced inspection drone, the IBIS2 Chainage. This innovative model enhances indoor infrastructure inspections, particularly for aging sewer systems, by combining worker safety with improved operational efficiency. This new drone retains the core features of the existing IBIS2 series while introducing new distance measurement, damage assessment, and report generation functionalities.

Development Background

In recent years, the risk of accidents due to aging infrastructures, such as road collapses from deteriorating sewers, has increased significantly. On July 15, 2026, the Japanese Senate passed the revised Sewerage Law, which mandates clear diagnostic criteria for inspecting sewer pipes. Municipalities will be required to disclose inspection results and countermeasures, emphasizing the need for transparent and precise inspection data for effective maintenance management.

However, challenges persisted in inspections involving beyond-visual-line-of-sight operations. Pilots and on-site personnel often found it difficult to objectively ascertain the drone’s position while monitoring from the ground, and video footage did not retain distance-related information, complicating the identification of abnormal locations. The newly released IBIS2 Chainage addresses these issues by facilitating a
