Traditionally, machine safety guidelines have prohibited most operator access to moving equipment, especially when that equipment is under automatic control. All that may change though, now that advanced safety technologies like PLCs, laser scanners, vision systems, and I/O systems are becoming faster, more responsive, and more capable. These devices can help facilitate greater interaction between human operators and automated equipment and processes while still maintaining an exceptional level of safety. In this article from MIT Technology Review, the possibilities of close collaboration between operators and equipment is explored.
