Apple researchers have unveiled a groundbreaking framework that aims to enhance the movement of non-humanoid robots, enabling them to interact more naturally and expressively with humans. This innovation could significantly improve the usability and effectiveness of robotic assistants in both domestic and professional environments.
The study, recently published on arXiv, introduces the Expressive and Functional Movement Design framework, or ELEGNT, which empowers robots to express intentions, emotions, and attitudes through movement, moving beyond mere task execution.
According to the robotics team at Apple, the research emphasizes that for robots to foster natural interaction with humans, their movement design must incorporate expressive elements — such as conveying intention and emotion — alongside traditional functional parameters like task efficiency and spatial limitations.

How a Desk Lamp Became the Ideal Test Subject for Robot Emotions
The focus of this research was a lamp-like robot, reminiscent of Pixar’s animated character Luxo Jr., which features a 6-axis robotic arm along with a light and projector in its head. The researchers equipped the robot with two distinct movement types: functional movements aimed at completing tasks and expressive movements intended to convey the robot’s emotional state.
During user trials with 21 participants, the results revealed that expressive movements noticeably enhanced users’ engagement with the robot. This effect was particularly significant during social interactions, such as playing music or having a conversation, while the impact was less pronounced in purely functional tasks, like adjusting the lighting.
One participant highlighted the importance of playfulness: “Without the playfulness, I might find this type of interaction with a robot annoying rather than welcome and engaging,” reflecting how expressive movements can make even intrusive robotic behavior feel more acceptable.

User Testing Reveals Age Differences in Robot Movement Preferences
This research emerges amid a growing interest among major technology firms in the potential of home robotics. Presently, most available home robots, like robotic vacuum cleaners, emphasize functionality; however, the findings suggest that integrating more natural and expressive movements could position future robots as more desirable companions.
The researchers caution that achieving a balance is vital. “There needs to be a balance between engagement through motion and quick task completion, otherwise the human might grow impatient,” one user noted.
Interestingly, the study found a generational divide: older participants exhibited markedly less enthusiasm for expressive robot movements, indicating that user preferences may necessitate tailored robotic behaviors.

The Future of Social Robotics: Striking a Balance Between Function and Expression
Although Apple seldom publicizes its advancements in robotics, this new research hints at a transformative direction for the company in home robotics. The study advocates for a paradigm shift in robot design: moving away from merely assessing what robots can accomplish to considering how their interactions affect human feelings.
The forthcoming challenge lies not only in programming robots to complete specific tasks but also in ensuring their presence is welcomed in our everyday environments. As robots transition from industrial applications to personal spaces, their acceptance may hinge less on operational efficiency and more on their ability to intuitively engage with users—both literally and metaphorically.
Apple’s findings are set to be showcased at the 2025 Designing Interactive Systems conference in Madeira this July.
The implications of this research underscore a future in which robot design will rely as heavily on insights from animators and behavioral scientists as on engineering expertise.
As robots become integrated into more homes and workplaces, crafting their movements to feel natural rather than mechanical could distinguish a fleeting gadget from a truly valuable companion. The real test for companies like Apple will be translating this research into user-friendly products that not only fulfill functional needs but also engage people on a personal level.
