Robot Butler

The Home Exploring Robot Butler (HERB) can often be seen through the glass walls of the Personal Robotics Lab in Newell-Simon Hall picking up iced tea bottles or taking books off a bookshelf. Complete with fingernails and a British accent, HERB is the perfect caregiver: The robot can open doors, microwave meals, and even separate an Oreo cookie from its cream. The focus is on complicated manipulation tasks with a lot of uncertainty and a lot of clutter. If you look at a factory floor, robots can do magical things. But if you look at a home — at least my home — it looks nothing like a factory floor. So researchers are trying to get robots like HERB to move from the factory floor to homes so they can perform useful tasks that a caregiver would perform.


Nevertheless, HERB rose to the challenge and starred in what is now a widely circulated YouTube video documenting the robot’s success in separating an Oreo’s cookie from its cream. Not only is HERB the only research robot to have ever completed the task, but the process through which its algorithms were improved to separate an Oreo resulted in the creation of new tools that will be useful in completing other tasks in the future. Despite HERB’s technical capabilities, the robot still needs to work on his manners. One of the things that we’ve noticed is that we spent five years on improving capability, but people are still hesitant to accept robots in their homes. It’s not just about capability — it’s about behavior, how situationally aware it is, and how sensitive it is to your own personal space.
