Sharing control with robots may make manufacturing safer, more efficient

A connected robot reaches for a colander in Bilge Mutlu’s UW–Madison lab, where studies have made robots better at working with remote human controllers.
Hulking robots common to assembly line manufacturing tend to be loners. They often cut, bend and weld metal inside cages and behind barriers meant to safely separate them from human workers. “For a long time, the best factory robot has been one that you set up, and you don’t touch for two years. It does the same thing over and over, unchanged, a million times,” says Bilge Mutlu, a University of Wisconsin–Madison professor of computer science, industrial engineering and psychology. “But because those robots are built to be very powerful and very accurate, they are also very dangerous for people. You can’t get in its way.”

In “shared control,” a human wired with sensors and controls guides a robot’s arms through the course of a task like sorting objects or mixing ingredients according to a recipe.
