Let’s remember Mac Barrett, father of the AGV
August 23, 2010 - MMH Editorial
Arthur “MAC” Barrett, Jr., 89, passed away a week ago, on August 17, in Lake Forest, Illinois. These days, MAC Barrett may not be a household name, but to those who have been around the industry long enough, he’s credited with inventing the world’s first automatic guided vehicle in 1954. His company was Barrett Electronics, and the “Guide-O-Matic” tracked a signal in a wire mounted on the ceiling of a factory or a warehouse. They weren’t called AGVs back then. Barrett called his invention a driverless vehicle. Soon after, wires were installed in a slot in the floor.
I had never heard of Barrett, but his passing was brought to my attention by Ken Ruehrdanz at Dematic. “My first job out of college was working for Barrett Electronics,” says Ruehrdanz. And while Ruehrdanz did not report directly to Barrett, he says he witnessed Barrett’s passion for product development and innovation. “He pioneered the use of radio controlled bridge cranes and radio controlled industrial vehicles called Radox, a system that allowed order selectors who were picking cases onto a pallet to automatically index a pallet truck or tow vehicle pulling trailers to the next pick location,” Ruehrdanz says. That sounds a lot like some of the robotic solutions being developed today.
Ruehrdanz also recalls that Barrett’s company bought back one of the original Guide-O-Matic vehicles from a customer who utilized it for over 20 years. “It was a red tow vehicle with toggle switches that allowed an operator to send the vehicle to a specific stop location,” Ruehrdanz says. “I don’t know where it is today, but if someone can find it, I recommend we send it to the Smithsonian in Washington.”
