Could the future of companion robots be soft, floating creatures instead of humanoid machines?
An international team of researchers, led by Japan’s Keio University, just introduced a soft floating robot (SFR) that’s inspired by Tinker Bell. Like the Peter Pan character, it floats safely through indoor spaces. But instead of magic, it uses a helium-filled body, small flapping wings, and sensors to drift around like a smart balloon.
Unlike a traditional drone, it’s designed to float quietly around people rather than avoid them and even make gentle contact without feeling dangerous. They could wake you up gently, remind you to take breaks and stay hydrated, or just drift around the room the switch up the vibes.
In their paper, the researchers said the robot’s weaknesses may make it more lovable, so people treat it more like a companion than a machine.
“The SFR’s inherent clumsiness and balloon-like fragility align with the ‘weak robot’ concept and design approaches that frame vulnerability as a mechanism to elicit care,” they wrote. “When it gets stuck in a draft, it looks like a clumsy puppy asking for help. This vulnerability is not a functional failure but a relational resource, fostering empathy and attachment through acts of care.”
But there are also engineering challenges. With limited payload capacity, floating robotic companions need ultralight batteries, motors, sensors, and computers or external AI processing and sensing systems.
The project also involved researchers from City University of Hong Kong, the University of Duisbuerg-Essen, MIT Media Lab, and Technische Universität Clausthal. They published their findings in the Association for Computing Machinery’s digital library.
