Funded by an ARC Linkage Project, UTS and RMS of NSW have been collaborating on research and development of biologically inspired robots for steel bridge inspection and condition assessment from 2010 to 2013. This research has addressed the research challenges and developed methodologies, including methods and algorithms for sensing, exploration, 3D map building, collision avoidance, control and robot design, that enables a climbing robot to navigate in steel bridge structures, collect bridge condition data and conduct condition assessment. A lot of engineering challenges has also been addressed including the design of the 7DOF inchworm robot and a novel adhesion pad. A prototype climbing robot has been developed and tested in field trials.
The project “Development of a Deployable Climbing Robot for the SHB Inspection and Condition Assessment” is Stage 2 of this research with the objective of developing one practically deployable climbing robot for the SHB inspection and condition assessment. This robot is expected to:
- be capable of navigating in the complex bridge structure and areas which are difficult for human workers to access (e.g. box girder structure)
- acquire information to facilitate condition assessment of steel bridge structures while greatly reducing the associated occupational health and safety risks
- be robust and reliable
- be easy to set up and relocate on a steel bridge
