What is Mirumi?

Robot Accessory that Reacts to Sound and Touch: Mirumi

Mirumi is not just an accessory; it's a tiny robot friend that helps reduce user stress.

Developed by Yukai Engineering, Mirumi is introduced as a furry mini robot bag charm that reacts to sound and touch. Beyond being a fashion accessory, Mirumi positions itself as a "feeling" companion.

Mirumi, brought to life by Yukai Engineering, specialists in "lifestyle robots," resembles a mix of a small yeti, an owl, and a Sesame Street character. Its facial expression is described as a "Gen-Z gaze," referring to today's youth. Its arms can firmly wrap around most bag straps, umbrella handles, belt loops, or straps; its size is small enough to be comfortably held in the hand. Its outer surface is covered with soft, furry material in pastel pink, gray, and beige tones, reminiscent of a teddy bear.

A curious gaze, a tiny spark of happiness

Mirumi's main distinguishing feature is its interaction with movement. Motors inside its body allow it to tilt and turn its head. These movements are based on three main inputs: touch, sound, and internal actions. A sensor on its head detects when the user pets it; two separate sound sensors detect nearby conversations or noises. Thanks to its neck motor, Mirumi can look up and sometimes appears to be observing its surroundings by turning its gaze away and then back again.

Behind Mirumi's seemingly spontaneous behaviors lies a special algorithm developed by Yukai Engineering. This system, drawing from experience in social robotics, ensures that reactions appear natural by selecting motor movements without repetition. The algorithm also triggers "random behaviors," allowing Mirumi to move on its own even without external stimuli. Mirumi has no screen; it conveys its emotions solely through physical gestures like nodding, tilting, and turning its head, expressing excitement or interest.

Mirumi gets its energy from an internal and rechargeable battery and charges via a Type-C input at the back. A "natural" signal has also been conceived for low battery status: Mirumi begins to slowly nod its head as if tired after a long day.

When the shy gaze of this small robot, which notices its surroundings and turns to look, meets the user, it aims to create an unexpected moment of joy, much like a baby suddenly looking at you on a crowded train. Moreover, Mirumi aims to make not only its owner happy but also those around it; for example, if it's attached to your backpack and turns to look at someone behind you on the train, it can turn into a pleasant surprise for the other person.
