Cleaning the Sydney Harbour Bridge used to be a dangerous, dirty and laborious job. As soon as a team of workers, operating a sandblaster, reached one end of the iconic structure they had to start again to keep 485,000 square metres of steel pristine.
Now two robots called Rosie and Sandy, built by SABRE Autonomous Solutions, blast away paint and corrosion all day long without a break. They determine which area needs most attention via a laser scan and move about on rails.
Scientists at the Fraunhofer Institute for manufacturing, engineering and automation demonstrated a Care-O-Bot that sweeps office floors and empties waste paper bins. Pal Robotics showed Stockbot, which walks the aisles in a shop or warehouse to check inventory at night.
Oppent’s autonomous vehicles ferry laundry or waste around hospitals, Yaskawa Motoman’s dual arm robot prepares laboratory samples and OC Robotics, a Bristol-based company, supplies snake-arm robots to inspect hazardous or confined spaces such as nuclear power plants and inside aircraft wings
Approximately 95,000 new professional service robots, worth some $17.1bn, are set to be installed for professional use between 2013 and 2015, according to the International Federation of Robotics. That excludes an estimated 22m domestic service robots – the autonomous vacuum cleaners and lawnmowers that are already becoming a familiar sight to consumers.
