A good recollection, Charles. I can recall visiting some science fairs in the late 1950's and early 1960"s and seeing various computational functions executed in hard-coded relay logic. And I have seen some of the older industrical control panels with a hundred or more of the little "ice cube" type relays, all running some fairly complex machines. Those were more the logic type of relays, while the cast-offs that I had were more toward the power types, with contacts designed to switch ten amp loads all day long.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
