Sorting
The latest generation of sorting systems can detect hard-to-find defects with high accuracy “We want to reach 100% detection so sorting can eventually be done with zero personnel,” says Roland Scheffer of Ellips, which focuses on optimizing sorting processes. He and his colleagues, Jody Bakker, Mitchel Bakker, and Adriaan Vet, say Ellips has recently taken the next step in that process. It introduced a new deep learning module, TrueAI, which is part of its new TrueSort 2 software platform..
