Travis Deyle on “Do robots need heads?”

15 August 2013

share this: 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, as even mundane robots like the Roomba are anthropomorphized (taking on human-like qualities) without a head. A follow-up question might be, “How are heads useful?” For humans, the reasons are apparent: food intake, a vessel for our brain, a locus for sensors (eyes and ears), and high-bandwidth communication via expression. What about for robots …?

  • Food intake: Probably not.
  • Computational storage: Again, probably not.
  • Location for sensors: Indeed, the apex of a robot is a natural, obstacle-free vantage point for non-contact sensors. But a “head” form factor is not a strict requirement.
  • Emotion and expression: Ah, the real meat of this question… “Do robots need to express emotion?”

This is a funny question to ask someone who once (in)famously advocated for either (A) extremely utilitarian designs: “I want my eventual home robot to be as unobtrusive as a trashcan or dishwasher”, or (B) designs unconstrained by the human form factor: “Why not give robots lots of arms (or only one)? Why impose human-like joint limits, arm configurations, and sensing? We can design our own mechanical lifeforms!”

My views have softened a bit over time. Early (expensive) general-purpose home robots will almost certainly have humanoid characteristics and have heads with the ability to express emotions (i.e. be social) — if nothing else, to appeal to the paying masses. And these robots will be useful: doing my laundry, cleaning my dishes, and cooking my meals. In the early attempts, I will still find their shallow attempts at emotion mundane and I will probably detest the sales pitches about “AI” and “robots that feel.” But as the emotional expressions become more natural and nuanced, and the robots become more capable, I will probably warm up to the idea myself.

TL;DR: No, many robots do not need heads. Even social robots may not need heads, but (whether I want them to or not) they probably will, because paying consumers will expect it.

A robot that finds lost items

Researchers at MIT have created RFusion, a robotic arm with a camera and radio frequency (RF) antenna attached to its gripper, that fuses signals from the antenna with visual input from the camera to locate and retrieve an item, even if the item is buried under a pile and completely out of view.
