Researchers developed a helium-filled soft robot that floats through indoor spaces using flapping wings instead of propellers.
Its 70-gram, touch-safe body is designed for close interaction with people. In an earlier study, 92% of participants spontaneously touched it.
The team’s new ACM DIS 2026 Best Paper explores future floating companions that could follow people, guide breathing, interact with pets or deliver gentle reminders.
These remain research prototypes and design concepts - not yet an autonomous consumer product.
