Apple has developed a new framework called ELEGNT that enables robots to move more naturally and expressively when interacting with humans, potentially making them more engaging as home assistants.
The breakthrough technology: The Expressive and Functional Movement Design (ELEGNT) framework allows non-humanoid robots to communicate intentions, emotions, and attitudes through their movements while performing tasks.
- The system was tested using a lamp-like robot with a 6-axis robotic arm and a head containing a light and projector
- Researchers programmed both functional movements for completing tasks and expressive movements to convey the robot’s internal state
- The design was inspired by animated characters, specifically drawing parallels to Pixar’s Luxo Jr.
Research findings and user response: A study involving 21 participants demonstrated that expressive movements significantly improved human engagement with the robot.
- Users reported more positive interactions during social tasks like playing music or conversation
- The expressive movements made potentially intrusive robot behaviors more acceptable to users
- Functional tasks like adjusting lighting showed less impact from the added expressiveness
- Older participants showed lower receptivity to expressive robot movements
Technical implementation: ELEGNT represents a shift in robotics design philosophy that balances functionality with social interaction.
- The framework integrates traditional robotic considerations like task fulfillment and spatial constraints
- Movement design incorporates elements like intention, attention, and emotions
- Researchers emphasized the importance of balancing engaging movements with efficient task completion
Industry implications: Apple’s research suggests a new direction for home robotics that prioritizes user experience and emotional connection.
- Current home robots primarily focus on functional tasks, like robot vacuums
- The research indicates future robots may need to balance efficiency with social engagement
- Implementation may require customizable behavior settings to accommodate different user preferences
- The framework could influence how major tech companies approach home robotics development
Looking ahead: The social robotics challenge: The success of future home robots may depend more on their ability to create comfortable interactions than on pure efficiency.
- The research will be presented at the 2025 Designing Interactive Systems conference in Madeira
- Development of socially acceptable robots will likely require input from animators and behavioral psychologists alongside engineers
- The ultimate challenge lies in creating robots that people actively want to interact with, rather than merely tolerate

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
