Mirumi clings tightly to handles as a mini attachable robot

 

Mirumi, a mini attachable robot, clings tightly onto bag handles and moves its head when users pet it. No longer a prototype, the portable device looks around and reacts to what happens near it or on it using the ‘special’ algorithm that the design team has developed. To recap, Yukai Engineering, the mastermind behind the project, debuted Mirumi at CES 2025, and back then it was a prototype. Soon, the mini attachable robot is expected to come to life, at least mechanically, as a fashion accessory users can clip on their bag handles and even belt loops.

 

Mirumi has a head, a body, and two arms that wrap around straps or poles. The shape lets the robot hold onto thin and thick objects without falling, and the compact size of the device can fit in the user’s two hands. Its furry skin resembling teddy bears is soft to touch, and the team says they use materials sourced from Japan and in custom colors to make the device’s smooth finish and its friendly outline. The design team works on how the mini attachable robot Mirumi looks at people, with its neck motor lifting the head to make it look up. The timing of the movement is programmed so the robot sometimes turns away again before it looks back.

portable device that shakes its head slowly when low in battery

 

To make it move, the Yukai Engineering team installs motors inside the body of the mini attachable robot Mirumi. These motors tilt and turn the head in different directions, and they also help the device respond to three main inputs: sound, touch, and internal triggers. When someone pats the head, a sensor in the head detects the action. When a sound or voice is near, two sound sensors inside the body pick it up. Signals travel through a chip that controls the motor actions, and this system allows many reactions without repeated patterns. Mirumi sometimes moves on its own even when nothing is happening, creating the feeling that the robot is active. 

 

The random behavior comes from a custom algorithm, which selects reactions in a way that appears natural. The team uses experience from earlier social robots to build these responses as well as from their prototype earlier in 2025. For the real-life model, the device comes with a built-in battery, rechargeable using a Type-C cable behind the mini attachable robot. Mirumi also gestures when its battery is low by shaking its head slowly. It’s a way for the team to have a completely screen-free device for telling users it’s time to charge their gadget. Mirumi doesn’t talk, at least for the recent model. It only turns its head, nods, and gently tilts to show excitement, hesitation, or interest. Fans of the mini attachable robot can support the campaign, and the team expects to ship Mirumi in May 2026.

Yukai Engineering introduces Mirumi at CES 2025

 

At CES 2025, Yukai Engineering reveals Mirumi, a clip-on furry robot that interacts with people by looking and nodding at them. The furry robot holds onto the bag handles like a koala or a sloth, and when it rotates its head, it slightly bows to acknowledge passersby. The device, a sibling of Nékojita FuFu blowing on hot meals to cool them down, uses an inertial measurement unit to detect movements, such as when someone taps the furry robot or moves the bag. The internal distance sensor helps it gauge its surroundings, so it can respond in time by rotating its head.

 

Mirumi has a number of behavioral patterns, as visitors can see at CES 2025. The furry robot looks around once the bag moves and also rotates its head when it spots a moving person or object and follows them with its gaze. But Mirumi is shy. It hides its face, away from the people, when it sees someone suddenly pet it or appear in front of it. It even shakes its head sideways when someone jiggles it as a way to say, ‘don’t do that.’ Visitors have the chance to see Yukai Engineering’s furry robot at CES 2025 between January 7th and 10th at the Venetian Expo in Las Vegas.

FURRY ROBOT WITH PUPPY EYES AT CES 2025

 

What can lure in passersby to look at Mirumi is its googly eyes. They’re round and expressive, similar to puppy eyes, as if wanting people to interact with it. It has long arms like sloths, which Yukai Engineering has designed so they can easily hold onto bag straps. The design team also has to focus on the head and body weight of the device to balance the personal gadget and withstand the heaviness of mechanical parts.

 

Yukai Engineering shares that the idea for Mirumi has come from a team of staff engineers and designers. They proposed to create a robotic ‘yokai’, or a supernatural being, a creature but with the characteristics of the human baby. Lo and behold, here arrives Mirumi, the furry robot that embodies that pitch. After CES 2025, the robotics startup is set to launch a crowdfunding campaign for the furry robot in mid-2025.

Yukai Engineering brings mini robot Nékojita FuFu to CES 2025

 

Yukai Engineering unveils Nékojita FuFu at CES 2025, a portable and attachable mini robot that cools down hot drinks and food by blowing on them so people don’t have to. The Tokyo-based robotics startup brings the device to Las Vegas for the annual trade show, which runs between January 7th and 10th, 2025. The mini robot has an internal fan that produces the cooling air and breathes it out through its mouth.

 

At CES 2025, the startup shows how the mini robot works. It features an algorithm called the ‘Fu-ing System’. The setup allows for the mini robot to randomize its blowing strength and rhythm the same way people do. With this, the device can help cool down the drinks and food’s temperature. After CES 2025, Yukai Engineering expects to release its mini robot across Japan in mid-2025.

Bringing down hot temperature within 3 to 5 minutes

 

What sets Nékojita FuFu by Yukai Engineering apart is that it’s an attachable and portable mini robot and stand-alone device. Unlike conventional heat-reducing mug cups, users don’t need to plug it in because it has its own rechargeable battery. CES 2025 visitors can see that the mini robot resembles the silhouette of a cub. The robot’s name, however, combines the Japanese words, ‘neko-jita,’ or ‘cat tongue’. It comes from the phrase used to describe an intolerance of hot food.

 

The design has ‘paws’, which serve as its anchor so it can hang itself on any foodware (as long as it has a straight edge). Based on the design team’s testing data, the device can bring down the temperature of hot water in a cup from 190°F (88°C) to 160°F (71°C) and 151°F (66°C) in 3 and 5 minutes, respectively. This is compared to 176°F (80°C) and 171°F (77°C) without the mini robot. They have yet to release the data for cooling down hot food. The device unveiled at CES 2025 is attachable to straight-edge foodware around 0.08” to 0.23” (2mm-6mm) in thickness.

From ‘I’ve Got This’ to ‘Not Gonna Spill’ blowing mode

 

Yukai Engineering says that Nékojita FuFu has different ‘blowing’ modes. They show it at CES 2025, where the mini robot switches between the full-force ‘I’ve Got This’ and the gentler ‘Not Gonna Spill’ modes. The design team plans to add more in the future. It includes gradually increasing the blowing strength and a nonstop series of strong and short blows. So far, the team only plans to release the mini robot in Japan.

gear up, zodiacs: an evolution in robotics is nigh…

and humans have been working towards it for at least two millennia. sure the science of robotics only came about in the 20th century, but if you really want to stretch it, the history of human-invented automation could be traced back to ancient greece. back then descriptions of robots known as automatons were documented – that’s non-electronic moving machines mimicing human or animal actions – and ever since, the ambition of engineers from all over the world has been to elevate simple mimicking to exact replication!

recent research coining the term ‘digisexuality’ hints at new year experiences for the human race. it describes ‘people whose primary sexual identity comes through the use of technology’ – a thought either demonstrating the first steps away from robot fetishism and into the realm of true interpersonal connection..or the end of healthy human relationships altogether. remember samantha the sex doll? she broke down after being manhandled at a tech fair. the human doll caused controversial debate after its’ inventor boasted samantha’s ability to ‘enjoy sex’ and synchronise with with her partner to ‘mutually climax’. meanwhile, a harvard university professor has claimed that sex robots might make men, not women, obsolete. it comes at a time when sex doll manufacturers such as realbotix are beginning to acknowledge the market for male sex dolls… their application enables users to match an AI personality with a humanoid robot head, to create the most realistic sex doll imaginable – see here. these ‘advancements’ query how human nature would evolve if we got used to having sex with ultra-life-like humanoids whenever and however we wanted – would you expect complete dominance in your relationships with humans? the fear of robots sinister social consequences is one that’s in danger of becoming flesh.
