Robot Knows the Right Question to Ask When It’s Confused

Understanding when they don’t understand will help make robots more useful

Last week, we (and most of the rest of the internet) covered some research from MIT that uses a brain interface to help robots correct themselves when they’re about to make a mistake. This is very cool, very futuristic stuff, but it only works if you wear a very, very silly hat that can classify your brain waves in 10 milliseconds flat.

At Brown University, researchers in Stefanie Tellex’s lab are working on a more social approach to helping robots more accurately interact with humans. By enabling a robot to model its own confusion in an interactive object-fetching task, the robot can ask relevant clarifying questions when necessary to help understand exactly what humans want. No hats required.
