Robohub.org - robot_facial_expressionsRobots are machines and most people agree that they primarily serve a utilitarian purpose. So why do so many of them have heads? Here are some thoughts by AJung Moon, Mark Stephen Meadows, Travis Deyle, and David Robert.

AJung Moon on “Do robots need heads?”

Are you curious about what your future robotic assistants will look like? My bet is that by the time you buy your very first robotic butler, it will have a friendly head on it that moves. In fact, it would be a good idea to make robots with heads if they are intended to share spaces and objects with people. That’s because …

Mark Stephen Meadows on “Do robots need heads?”

I don’t know about you, but if something has a head I assume it has thoughts. When watching a movie I stare at the character’s face because I want to know what they feel. So for me a head’s a pretty important thing. If I’m going to talk with a robot, …

Travis Deyle on “Do robots need heads?”

The obvious answer to this question is “No: there are lots of robots without heads.” It’s not even clear that social robots necessarily require a head, …

David Robert on “Do robots need heads?”

As a robot animator I can attest to the fact that robots don’t “need” heads to be treated as social entities. Research has shown that people will befriend a stick as long as it moves properly. We have a long-standing habit of anthropomorphizing things that aren’t human by attributing to them human-level personality traits or internal motivations based on cognitive-affective architectures that just aren’t there. …

Robohub.org-baxterAre you curious about what your future robotic assistants will look like?

My bet is that by the time you buy your very first robotic butler, it will have a friendly head on it that moves. In fact, it would be a good idea to make robots with heads if they are intended to share spaces and objects with people. That’s because the head is a really expressive part of our body we naturally use (a lot) to convey essential information to each other.  Robots will need to do the same if they are going to hang out with us soft-tissued human beings at our homes and offices.

For example, when people are attending to something, they tend to be looking at the thing they are attending to. People also look at the direction they are headed when they walk, and make eye contact when they talk. People nod with their head when they want to show agreement about what is being said. Without these nonverbal cues from the head interacting with each other would be much more difficult, because we wouldn’t know what each other are doing.

Rodney Brooks, a pioneer in robotics and now Chairman and CTO of Rethink Robotics, had this in mind when he built Baxter. Although Baxter’s arms are as bulky-looking as its traditional industrial robotics predecessors, one of the innovative components of it is the fact that it features a moving head that makes its interaction with not-so-trained users very intuitive

If robots are to do meaningful things around us in a safe manner, it’s essential that we know what the robot is attending to, where it is headed, and what it is about to do – a lot of which a robot head can help with. That way, we won’t have to be a roboticist to know when it is safe to be around a robot holding on to a giant knife to make you cucumber salad. <optionally embed cucumber slicing robot
