A New Approach Enabling Intuitive Robotic Helpers for Household, Workplace, and Warehouse settings

For a robot, the real world is a lot to take in. Making sense of every data point in a scene can take a huge amount of computational effort and time. Using that information to then decide how to best help a human is an even thornier exercise. Now, MIT roboticists have a way to cut through the data noise, to help robots focus on the features in a scene that are most relevant for assisting humans. Read on to learn more.

Getting Robots to “Bee” have Without a Plan
