A new climbing robot is conducting inspections across the 7.2kms network of tunnels in the Sydney Harbour Bridge deemed too dangerous for human workers . Developed over five years by the University of Technology Sydney and NSW Roads and Maritime Services , the robot has magnetic feet , can crawl through tiny tunnels and confined spaces , and unlike a human inspector , is not at risk of asphyxiation . The paintwork inside this part of the bridge dates back to 1932. Engineers interpret real - time information that is sent back from the robot . The next phase of the project , ready in three years , is to develop a robot that can vaporize rust using laser beams and re - paint the section at the same time . This " world - first " development could have important application overseas , including use in transmission towers , ship ##building and nuclear reactors .
