Since 2005, the project team has been developing a fully autonomous steel bridge maintenance robotic system. In collaboration with the NSW Roads and Maritime Services (RMS), the team has developed methodologies that enable a robot to conduct the following tasks automatically: exploring an unknown environment, building 3D map of the environment, planning suitable blasting path and robot collision-free motion, and conducting grit-blasting. Two practically deployable robotic systems have been used in the Sydney Harbour Bridge maintenance sites since 2013.
This research project aims to extend the functionality of the grit-blasting robotic systems by developing methodologies that enable:
- Automated monitoring of robotic grit-blasting process
- Automated inspection of surface quality
- Control of the robotic system for blasting surface spots that are missed out in previous blasting operation, or where the quality is not good enough.
- Multiple grit-blasting robotic systems to operate collaboratively in a blasting environment.
