Or used to be, before they broke down.“They had been working on and off. It’s been about two years since they were running,” said Bret Kulakovich, an adjunct professor at PSU who oversees the school’s robotics lab as part of its bachelor’s degree in robotics.The solar-powered, stationary robots were developed to scare birds away from vineyards using sound, lasers and even propane-fueled air cannons triggered by motion detection. Six had been bought by Casella, the waste management firm, which used them to scare away scavengers from landfills. But maintenance had lagged and help was needed PSU heard about them through an alumnus and Kulakovich thought they sounded perfect. “There was a course coming up in industrial robotics, and I like having real-world applications. We’re just starting out as well, and it’s nice to work on something other than in-class problems,” he said. Upon their arrival, it was obvious that a lot of work had to be done. “They had a lot of working parts, but just not all the parts and some parts that worked weren’t in good shape,” said Kulakovich, pointing to things like a lurking wasp’s nest, lack of power to fans that caused overheating, and “a gearbox for the rotating turret — it made a jingling noise. That’s not what you want to hear.” The big problem, however, was lack of knowledge for systems that dated back a decade or more.“These were either not labeled at all or made up of components that weren’t sold for the past five or six years. The company that had originally done the software and integration was out of business,” said Kulakovich. “The operating system was Linux, but it was installed in French. The notes for the components were in Chinese. But not all the notes — some were in French,” he said, noting that the name of the Linux distribution “wasn’t Ubuntu, it was L’Ubuntu.” To understand the circuit board controlling the robot they had to find the manufacturer, starting with Google image searches. “Eventually we had a website posting on Ali Express,” a Chinese shopping site, but details were in Hebrew. “It had the appearance of that part, gave us the name of the manufacturer and part number and we found some pages scanned in from a manual.” The next step is a big one as the team tries to give Casella a scalable solution: Deciding whether to keep repairing what’s there, or to redesign it and rebuild it from scratch, taking advantage of a decade’s improvements in software, electronics and hardware. That’s exactly the sort of decision-making that college courses should teach, Kulakovich noted: “There are certainly some forensic adventures going on.” The robotics degree, which PSU says was the first of its kind in state, launched in 2021. It recently received a $1 million federal grant to help build a new robotics lab.</div></body>
