I love the expressiveness of the lamp in the video accompanying this research paper from the Apple Machine Learning Research team. It will seem immediately familiar to anyone who’s watched a Pixar movie.

The paper explores the benefits of expressive and human-relatable movement in non-anthropomorphic robots:

Nonverbal behaviors such as posture, gestures, and gaze are essential for conveying internal states, both consciously and unconsciously, in human interaction. For robots to interact more naturally with humans, robot movement design should likewise integrate expressive qualities—such as intention, attention, and emotions—alongside traditional functional considerations like task fulfillment, spatial constraints, and time efficiency. In this paper, we present the design and prototyping of a lamp-like robot that explores the interplay between functional and expressive objectives in movement design.

The robot lamp—I’m going to name it Elle, after its project name, ELEGNT—Elle reacts to the researcher’s voice and hand gestures, and responds with movement, sound, video, and voice. When the researcher asks Elle about the weather, Elle gazes out the window, then turns back and answers. After the researcher suggests it’s a nice day for a walk, Elle asks if it can go too, and hangs its lamp-head dejectedly when told no.

(I actually went awww!)

One of the (many) things that makes robotic characters like R2D2, Wall•E, or C1-10P so endearing is their obvious personality. They couldn’t speak words, yet we understood them, as we do Elle. (I’m hoping the name sticks!)

In the video, Elle has a less expressive, more functional counterpart—I’ll just call it Al—which performs the same tasks, but without the playfulness. Al got the job done, but was more direct and, well, robotic. The video shows them in split-screen, and I found Elle to be infinitely more delightful.

(The research suggests appreciation for the playful Elle drops with age. I may be an outlier here, though I could see myself getting frustrated if I continuously have to wait for answers while it emotes.)

One of Apple’s best designs (and one of my favorites) was the iMac G4—an all-in-one with an LCD screen atop an articulating arm that’s attached to a snow cone white dome. The ad for that iMac shows it mimicking—some might say mocking—a man on the street with very expressive movements, even sticking out its “tongue” in the form of an ejectable CD holder.

There’s been a long-standing rumor that Apple is working on robots for the home. When I saw the research video, I immediately hoped Apple would revive that iMac G4 design for Elle—I would buy one in a heartbeat.

The research highlights one of Apple’s best traits: a desire to go beyond the mere functional, and to imbue objects with personality. Whether it’s the original Macintosh (“It sure is nice to get out of that bag!”), the sad low-battery tones of AirPods, or the kinetic bounciness of the iPhone Dynamic Island, Apple’s magic is in building expressive, not just functional, products.

As my friend @Denisvengeance@sfba.social astutely noted, “this is what makes Apple Apple.”
