Human and robot co-workers more efficient, less accident-prone
More and more processes are being automated and digitized. Self-driving delivery vehicles, such as forklifts, are finding their way into many areas—and companies are reporting potential time and cost savings. However, an interdisciplinary research team from the universities of Göttingen, Duisburg-Essen and Trier has observed that cooperation between humans and machines can work much better than just human or just robot teams alone. The results were published in the International Journal of Advanced Manufacturing Technologies.
The research team simulated a process from production logistics, such as the typical supply of materials for use in the car or engineering industries. A team of human drivers, a team of robots and a mixed team of humans and robots were assigned transport tasks using vehicles. The time they needed was measured. The mixed team of humans and robots were able to beat the other teams; this coordination of processes was most efficient and caused the fewest accidents. This was quite unexpected, as the highest levels of efficiency are often assumed to belong to those systems that are completely automated.
“This brings a crucial ray of hope when considering efficiency in all discussions involving automation and digitization,” says the first author of the study, Professor Matthias Klumpp from the University of Göttingen. “There will also be many scenarios and uses in the future where mixed teams of robots and humans are superior to entirely…
