Sydney Harbour Bridge Robot

Roads and Maritime Services continues to innovate with award-winning technology inspired by nature. This autonomous climbing robot (CROC) is used to inspect difficult to reach areas of the Harbour Bridge.

Updates and announcements

Roads and Maritime Services and University of Technology (UTS) awarded 2015 Asia Pacific ICT Alliance (APICTA) Award in the Industry Application Category, "Bio-Inspired Autonomous Climbing Robot - A Revolutionary ICT Solution to Inspection and Maintenance of Steel Structures".

Meet CROC

The robot, called CROC, is the result of six years collaborative research and development. The autonomous climbing robot is inspired by the inchworm’s ability to climb a range of surfaces and difficult to navigate structures. CROC is a fully autonomous robot with seven degrees of freedom complete with a 3D sensor and a high definition camera. This means it can automatically explore complex environments like the interior of the box girder arches of the Sydney Harbour Bridge.

The robot is able to plan its own path using maps generated from its 3D sensor whilst gathering HD images. The images are collected and stored into a Geographic Information System (GIS) to help inspectors assess bridge conditions.

Collaboration with University of Technology Sydney (UTS)

Roads and Maritime worked collaboratively with UTS to develop a robotic system for steel bridge inspection and condition assessment. This technology reduces the risks involved in as bridge inspections and improves the overall health and safety of workers.

The research was funded by Roads and Maritime, the Australian Research Council and the Centre for Autonomous Systems at UTS.
