Komatsu’s Jason Anetsberger, director of customer solutions, said that it’s becoming common practice to apply automation and analysis at customer sites. “In the past few years, however, advances including low-cost laser sensors, cheaper robotic arms and grippers, and open-source software for navigation and computer vision have made it possible to automate and analyze more construction.” “It has long been impractical to deploy robots at construction sites because the environment is so varied, complex and changing,” writes Knight. That may change as technology advances, according to Will Knight in Wired. In practice, application is difficult because the assumptions you need to make in order to develop the theories end up being really hard to map on physical robots.” There is a lot of really cool theory on robot construction, such as using a large swarm of termite-inspired bots that work together to build a structure. “Programming them to move on to a completely different function is a challenge that will have to be overcome. “Right now, SAM and others like that are useful at one thing,” Napp pointed out. He said these examples of “cobots” - robots that are built to work alongside humans - are good at what they do, but they have limitations. Nils Napp, an assistant professor at Cornell University’s School of Electrical and Computer Engineering, and his students are studying robotics for building and other applications.
In limited instances, automated or semi-automated devices are already working alongside humans. Robotics use in construction continues to make headway, though, as technology rapidly advances and the need for new solutions to worker shortages remains strong.
SAM’s just there to do the heavy lifting.” It still requires a mason to work alongside it. What SAM does is to pick up the bricks, put mortar on them, and puts them on the wall. “This is about collaboration between human workers and machines. “We don’t see construction sites being fully automated for decades, if not centuries,” Zachary Podkaminer of Construction Robotics, the New York-based company that developed SAM, told Digital Trends in 2017. So, does that mean a crew of SAMs can or even should replace a human crew? Not any time soon, according to one expert. A human bricklayer typically averages around 500. For example, using a conveyor belt, robotic arm and concrete pump, Construction Robotics’ SAM100 (Semi-Automated Mason) can lay 3,000 bricks per day as it works alongside a mason. Numerically, there are some clear wins for productivity when you leverage the repeatability of a robotic element to get work done, versus the variability of human work. Could robots, smart systems and automated processes someday soon control the full operation of a construction site? Would it make the job of a project manager easier or harder in the short term? Long term?
