In the fast-paced world of consumer tech, few products manage to balance innovation, charm, and emotional connection. But Yukai Engineering, the Japan-based company known for creating quirky yet heartfelt robot, has done it again. Unveiled and honored at CES, Mirumi—a palm-sized “joy” robot that reacts to touch—is capturing attention for all the right reasons.
CES (Consumer Electronics Show), the world’s largest and most influential tech event, is a launchpad for futuristic innovations. But in 2025, among the sea of ultra-fast processors, foldable screens, and AI assistants, one tiny robot stood out—not for its power, but for its personality.
What is Mirumi?
Mirumi is a small, soft robot designed to sit in the palm of your hand. It features subtle movements and a unique set of expressions designed to respond to human touch. With a soft body, reactive lights, and the ability to “breathe” gently, Mirumi doesn’t perform complex tasks—instead, it exists to bring comfort, relaxation, and emotional joy to its user.
As described by Yukai Engineering, Mirumi is not a toy or productivity tool but a “robotic expression of whimsy and delight.” It senses touch and reacts with gentle lighting patterns, motion, and sometimes even slight wiggles that feel like a robotic purr.
Its size makes it perfect for carrying in a pocket or bag, and its presence is meant to make users smile during stressful moments. It’s a wellness companion in the most unconventional form.
How Does Mirumi Work?
Mirumi uses a blend of soft robotics and haptic feedback to respond to its environment. Equipped with touch sensors and subtle motors, it recognizes when it’s being held, petted, or tapped. Each interaction prompts a unique light or movement pattern that mimics emotional feedback.
The robot doesn’t speak, but it communicates through colors and motion. Mirumi’s developers say this was intentional. By avoiding language, Mirumi becomes universally relatable—anyone, regardless of language or culture, can feel connected to it.
Inside, it houses a microcontroller and a gentle lighting system. Its software is programmed to ensure every interaction is slightly different, so Mirumi feels alive rather than repetitive. It also comes with a USB-C charging port, and its battery can last for several hours on a single charge.
A CES 2025 Award Winner
At CES 2025, Mirumi won a CES Innovation Award in the Robotics category. Judges and attendees praised the robot for pushing the boundaries of what robotics can mean. Instead of being focused on utility or productivity, Mirumi reminds us that technology can serve emotional and psychological well-being too.
This recognition aligns with Yukai Engineering’s past reputation. The company previously made headlines with robots like Qoobo, the therapeutic pillow with a wagging tail, and Bocco Emo, a smart home companion with emotional expressions.
Why Mirumi Matters in Today’s World
In a time where loneliness and stress are rising across all age groups, Mirumi serves a small but significant role. While it doesn’t replace human interaction, it creates a micro-moment of connection that is tactile, visual, and emotional.
Therapists and wellness experts have noted the potential of tactile gadgets like Mirumi in managing anxiety and promoting mindfulness. By providing a calming interaction, Mirumi can support users during work breaks, study sessions, or even moments of emotional overwhelm.
Additionally, its minimalistic design and soft feedback loop make it suitable for people with sensory sensitivities, including children or neurodivergent individuals who may find comfort in repetitive touch and gentle response.
Tech Specs and Features
- Size: Palm-sized (roughly 3 inches long)
- Weight: Lightweight; easy to carry anywhere

Final Thoughts: Joy in the Smallest Package
While CES is often about powerful processors, smart glasses, and electric vehicles, Mirumi stole the show in the most unexpected way. It reminds us that not all tech has to be groundbreaking in specs—some of it just needs to touch the heart.
Mirumi proves that the future of robotics isn’t just about AI and automation—it’s also about emotional presence, comfort, and delight.
Whether you’re a stressed office worker, a student needing calm, or just someone who loves cute robots, Mirumi offers a new kind of joy—soft, subtle, and very real.
