A Japanese robotics researcher is going viral this week after unveiling a soft robotic device designed to mimic the sensation and motion of a human tongue — and yes, the internet has thoughts.
Ryota Shijo’s so-called “Licker” robot, detailed in a newly released 2026 study, is built using flexible elastomer materials and embedded actuators that replicate natural tongue movement. A brief six-second demo circulating online shows the device bending up and down, swinging left to right and flexing symmetrically in smooth, wave-like motions — advancements that highlight just how far compliant robotics has come from its rigid, metallic predecessors.
Unlike traditional robots that rely on stiff joints and mechanical precision, Shijo’s prototype leans into soft robotics — an engineering approach that uses rubber-like polymers and flexible internal systems to create safer, more lifelike interactions. The tongue-shaped device is designed to deform and move organically, with researchers studying real human tongue kinematics to program its motion patterns.
While social media users have zeroed in on the invention’s shock value, the intended applications are far more clinical than comedic. According to the study, the technology is being explored for therapeutic uses, including elderly care and emotional bonding in companion robots. Japan, which continues to grapple with one of the world’s fastest-aging populations, has increasingly turned to robotics to address caregiver shortages and social isolation.
Soft robotics has already found its way into rehabilitation devices, prosthetics and assistive technologies. The Licker expands that conversation into tactile interaction — examining how realistic touch sensations might enhance human-robot relationships, particularly in care environments where comfort and emotional connection are key.
Online reaction has ranged from amused disbelief to predictable jokes about the future of intimacy tech. Many commenters framed the device as another example of Japan’s reputation for blending cutting-edge innovation with unconventional concepts. Still, engagement so far suggests the clip is more niche curiosity than full-blown viral phenomenon.
Humor aside, researchers say the project represents a meaningful step forward in compliant robotic design. By refining soft materials and embedded actuation systems, the team aims to create machines that interact more naturally — and safely — with human bodies.
Whether it ultimately becomes a staple of therapeutic robotics or simply an internet talking point, the Licker underscores a broader shift in robotics toward touch, sensation and emotional realism — a future where machines aren’t just functional, but increasingly human in how they move and connect.
