Apple researchers have developed a brand new framework for making non-humanoid robots transfer extra naturally and expressively throughout interactions with individuals, doubtlessly paving the way in which for extra participating robotic assistants in houses and workplaces.
The analysis, revealed this month on arXiv, introduces Expressive and Practical Motion Design ELEGNT, which permits robots to convey intentions, feelings and attitudes by means of their actions — reasonably than simply finishing useful duties.
“For robots to interact more naturally with humans, robot movement design should integrate expressive qualities — such as intention, attention and emotions — alongside traditional functional considerations like task fulfillment, spatial constraints and time efficiency,” the researchers from Apple’s robotics crew write of their analysis paper.

How a desk lamp grew to become the proper check topic for robotic feelings
The examine targeted on a lamp-like robotic, harking back to Pixar’s animated Luxo Jr. character, outfitted with a 6-axis robotic arm and a head containing a lightweight and projector. The researchers programmed the robotic with two forms of actions: purely useful ones targeted on finishing duties, and extra expressive actions designed to speak the robotic’s inside state.
In person testing with 21 contributors, the expressive actions considerably improved individuals’s engagement with and notion of the robotic. This impact was particularly pronounced throughout social duties like taking part in music or participating in dialog, though it was much less impactful for purely useful duties like adjusting lighting.
“Without the playfulness, I might find this type of interaction with a robot annoying rather than welcome and engaging,” famous one examine participant, highlighting how expressive actions made even doubtlessly intrusive robotic behaviors extra acceptable.

Person testing reveals age hole in robotic motion preferences
The analysis comes as main tech corporations more and more discover house robotics. Whereas most present house robots like robotic vacuums focus purely on perform, this work means that including extra pure, expressive actions might make future robots extra interesting companions.
Nonetheless, the researchers notice that steadiness is essential. “There needs to be a balance between engagement through motion and speed completion of the task being given, otherwise the human might grow impatient,” one participant noticed.
The examine additionally discovered that older contributors have been considerably much less receptive to expressive robotic actions, suggesting that robotic habits might should be personalized primarily based on person preferences.
The robotic’s capabilities span from useful duties like offering studying gentle to social interactions corresponding to inventive options and playful companionship. (Credit score: Apple)
The way forward for social robotics: Discovering the candy spot between perform and expression
Whereas Apple not often discusses its robotics analysis publicly, this work presents intriguing hints about how the tech big would possibly strategy future house robots. The examine suggests a elementary shift in robotics design: As a substitute of focusing solely on what robots can do, corporations should think about how robots make individuals really feel.
The problem forward lies not simply in programming robots to finish duties, however in making their presence welcome in our most intimate areas. As robots transition from manufacturing facility flooring to dwelling rooms, their success might rely much less on uncooked effectivity and extra on their potential to learn the room — each actually and metaphorically.
Apple’s paper shall be introduced on the 2025 Designing Interactive Programs convention in Madeira this July.
The outcomes level to a future the place robotic design requires as a lot enter from animators and behavioral psychologists because it does from engineers.
As robots develop into extra frequent in houses and workplaces, making them transfer in ways in which really feel pure reasonably than mechanical may very well be the distinction between one other forgotten gadget and a very indispensable companion. The actual check shall be whether or not corporations like Apple can translate these analysis insights into merchandise that individuals not solely use, however genuinely wish to work together with.
