THIS WEEK, THE Democrats and President Trump are talking about a $2 trillion infrastructure plan, a number in line with American Society of Civil Engineers’ estimates for infrastructure needs, but it isn’t clear where the money will come from or if a bipartisan plan will actually move forward.
The ASCE’s 2017 report card gave America’s infrastructure a D+ with scant progress these last 20 years. “America’s infrastructure is like a third-world country,” said Ray LaHood, transportation secretary under President Obama. If we don’t make a major infrastructure investment, our enormous infrastructure needs will just keep growing. We need good new ideas to make the most of whatever money is approved by the federal government or local governments.
New technologies are threatening jobs but they also offer the possibility of completing projects we otherwise couldn’t afford, minimizing disruption, improving safety and optimizing systems in ways humans working alone could not. Robots and artificial intelligence can help us build the infrastructure we need, here and around the world. In short, the infrastructure robots are coming; in fact, some of them are already here.
In Minnesota, spider-like bridge inspection drones crawl along high abutments and into narrow gaps while hovering drones inspect the undersides of bridge decks. Their access is better, cheaper, and safer with less disruption of traffic. Gas pipe repair robots allow utility crews in Boston, NYC, and Edinburgh, Scotland, to finish a job in a third of the time, without digging up the street at every joint or interrupting service because the robots can safely work inside pressurized lines. In Saudi Arabia and Mexico, water pipe inspection robots are inserted in one fire hydrant, carried by the water flow and captured with a net at another fire hydrant down the line, reporting the locations of leaks a tenth to a third the size old methods could find. In Connecticut, drones are replacing low flying helicopters for power line inspections.
In Oslo, Norway, submarine drones are mapping the landscape of underwater garbage: old tires and toys, plastic bags and the carcasses of abandoned cars, so boats with cranes and human divers can be deployed to clean up the fjords.
But the next generation of these machines, it seems clear, will gain more autonomy, adopting computer vision, autonomous vehicle navigation and machine learning technologies. Semi-autonomous drones and robots are in testing and early commercial deployment for inspection of industrial assets, land surveying and sidewalk snow clearing.
It’s not a big step to imagine robots creeping through the gas and water lines all day and night, mapping their own course, quietly fixing leaks, docking at charging and maintenance stations as needed, like a Roomba underground. Above ground robots could patrol the roads, the power grid and the waterways, cleaning up trash and fixing potholes, electrical wires and bridges or reporting what they can’t fix, directing a human crew to the spot.
Machine learning software systems are learning to predict code violations, safety incidents, mechanical failures and natural disasters, directing robotic or human resources to intervene. They are being used for fire code, health code and industrial safety inspection prioritization in Pittsburgh, New York, New Orleans, Boston, Chicago and British Columbia, Canada. Rolls Royce is testing machine learning to predict engine failures. The oil and gas industry is automating the detection of serious pipeline corrosion, adding machine learning to the pipeline robot pigs it has used for decades. British Columbia is trying to predict elevator problems. Pittsburgh is trying to predict landslides on roads.
Robots, sensors and machine learning are being used to direct water to where we want it before it ever hits a pipeline and to reduce pollution. Tech startups in Boston and San Francisco are using sensors and machine learning to create hyperlocal air quality and weather data and predictions. In crowded industrial cities in Guangzhou, China, pollution-detecting airborne drones help law enforcement identify which factory should be punished for emissions. China has used chemical carrying drones to disperse smog and to make rain and is considering the creation of a vast network of fuel burning chambers, planes, drones and artillery, guided by real-time data from satellites, to seed clouds over the Tibetan plateau, the source of most of Asia’s biggest rivers, an area three times the size of Spain.
There’s a rising army of robots, ready to serve.
