What Is Cozmo?
Cozmo was originally developed by Anki as a small robot with tracks, a lift arm, a face display, and interactive cubes. It moves around on a desk or table, reacts with expressive animations, and can play games with users.
The official Cozmo page describes Cozmo 2.0 as a small robot with a big personality. The appeal is not only that Cozmo moves, but that it appears curious, reactive, and characterful.
Cozmo is also known for Code Lab, a programming-oriented mode where users can combine commands and actions to move the robot. This makes it easier for children to experience programming concepts through a physical robot rather than only through a screen.
As of 2026, buyers should be careful. The official store appears to emphasize accessories and educational materials such as replacement cubes, treads, workbooks, and coding curriculum. Before buying Cozmo, especially in Japan, check whether the robot itself is available, whether the app works with your current phone or tablet, whether warranty support is available, and whether the battery condition is acceptable.
What Is Mia?
Mia is a talking AI cat companion robot. It is designed to bring small moments of conversation, comfort, and presence into everyday life.
Mia's official site introduces features such as 100+ expressions, Japanese dialect voices, Google Calendar reminders, weather updates, and family voice features. Instead of being a programming toy, Mia is meant to be a small cat-shaped companion that talks to you.
If Cozmo is a robot you actively play with, Mia is a companion you keep nearby. Mia does not move around the table like Cozmo, but that also makes it easier to place on a desk, shelf, or bedside table without worrying about it falling.
Detailed Comparison
Cozmo Is Better for Play and Learning
Cozmo's biggest appeal is that it feels like a small physical robot. It moves on tracks, uses cubes, changes facial expressions, raises and lowers its lift, and reacts in ways that make it feel lively.
For children, this can be a good entry point into robotics and programming. The value is not only entertainment. It can help children understand that commands, sequences, and actions can control a real object.
Cozmo is a better fit if you want a robot for STEM learning, parent-child play, coding activities, or a tabletop gadget with movement.
Mia Is Better for Conversation and Everyday Comfort
Mia is not a programming robot. Its value is in voice, expressions, dialects, and everyday interaction.
Mia can fit into daily routines more quietly than a moving robot. It can sit on a desk or shelf, speak in a friendly way, and provide small moments of companionship. For people who live alone, elderly family members, or people who want a cute talking robot rather than a toy to operate, Mia is the more natural fit.
Mia's Japanese dialect feature is especially important. Standard AI voices can feel mechanical, while dialect speech can feel warmer and more familiar.
Desk Use: Movement vs Low-Distraction Presence
Cozmo needs space. Because it moves around, plays with cubes, and can approach table edges, it is best used during dedicated play time rather than left running beside a laptop, drinks, or documents.
Mia does not roam around, which makes it easier to place near a workspace. It does not replace work tools, but it can create a small emotional break through short voice interactions and expressions.
Price, Availability, and Support Notes
Cozmo Requires Careful Availability Checks
Cozmo is still well known, but buyers should remember that the original Anki business ended and the product history is complicated. Current official information exists through Anki / Digital Dream Labs-related channels, but availability can vary.
If buying Cozmo today, check the following before purchase:
- Whether the robot itself is new, used, or refurbished
- Whether the app works on your phone or tablet
- Whether the cubes, charger, and accessories are included
- Battery condition
- Warranty and return conditions
- Whether support is available in your region
This is especially important when buying from marketplace listings or used sellers.
Mia Has a Clearer Official Path in Japan
Mia has an official website and a clearer domestic product path for Japanese users. If your main purpose is Japanese voice interaction, dialect conversation, or a small companion for home use, Mia is easier to understand as a purchase.
Prices and models may change, so check the official site for the latest information.
What Amazon Reviews Say About Cozmo
Amazon.co.jp reviews for the TOMY COZMO listing show both sides of the product. Positive reviews praise Cozmo's cuteness, face recognition, games, and programming value. Critical reviews warn about defective units, connection issues, falling from tables, and support frustration.
The review text below is not reproduced in full. Instead, each representative review is summarized in enough detail to preserve the buying signals.
Positive Review: Fun, Cute, and Good for Family Play
One five-star review from July 23, 2018 describes Cozmo as fun and cute enough to strongly recommend.
The reviewer bought Cozmo for a nine-year-old child. They liked that Cozmo recognized different family members' faces and called them by name. That kind of recognition can make the robot feel personal, especially for children.
The review also mentions games, fist bumps, and many interaction options. The reviewer felt the feature set made the price seem reasonable, even inexpensive for what the robot could do.
The same review includes an important warning: Cozmo requires a tablet connection, and the tablet battery drains quickly. In other words, Cozmo is not a standalone companion. It should be treated as a robot-and-app experience.
Positive Review: It Starts to Feel Alive
Another five-star review from October 24, 2017 focuses on Cozmo's character.
The reviewer liked that Cozmo could look at a face and call a name after setup, act upset when ignored, invite the user to play games, sing, and change expressions often. The review presents Cozmo less as a simple toy and more as a small animated presence.
The reviewer also notes that Cozmo can react near the edge of a table, sometimes sounding surprised, although it may still fall. This is both charming and a practical warning.
They also liked that taking care of Cozmo and playing games helped unlock more things Cozmo could do. The programming-style mode, where users combine actions such as moving and turning, was seen as a useful way for children to touch basic programming ideas.
Critical Review: A Defective Unit Can Hide Cozmo's Real Appeal
A one-star review from September 24, 2017 says the setup was easy, but the robot did not behave as expected.
According to the review, the unit mostly repeated charging behavior and cube searching. The reviewer expected actions such as lifting cubes, but the robot never seemed to reach that level of play. They also felt the voice volume was too loud and could not find a volume menu in the robot or app.
The reviewer questioned whether Cozmo would really grow or whether the product was worth the price. Later updates explain that support judged the unit defective and arranged an exchange. The reviewer was also frustrated that the timing of the replacement was unclear.
After the replacement arrived, the reviewer wrote that the new unit moved completely differently from the first one. This suggests the original problem was likely an initial defect. The lesson is clear: if you buy Cozmo, test cube recognition, movement, app settings, sound controls, and basic play as early as possible.
Critical Review: Connection Trouble, Falling, and Support Frustration
Another one-star review from February 24, 2019 says the robot stopped working continuously for more than five minutes after about three weeks.
The reviewer contacted support and was asked to send the unit for inspection. They were frustrated by the need to prepare packaging and repeat details already described by email. Support later confirmed the reported behavior and offered a replacement.
The reviewer also described an incident where Cozmo lifted a cube and then fell from the table at high speed. Because Cozmo is expected to have edge-detection behavior, the fall made the reviewer question the product's safety and support explanation.
Importantly, the reviewer still acknowledged that Cozmo itself had rich expressions, could be played with, and could feel comforting when working properly. The negative experience came from defects and support handling. For buyers, this means Cozmo can be charming, but the purchase should be made with clear return, warranty, and inspection expectations.

Is Cozmo the Same as Anki Vector?
Cozmo and Anki Vector are often mentioned together, but they are not the same.
Cozmo is more play and learning oriented. Vector is closer to a small smart robot with more focus on autonomy and voice features. If you want a moving desk robot, it is worth comparing Cozmo, Vector, and EMO before deciding.

Summary
Cozmo and Mia are both small robots with personality, but they serve different needs.
Cozmo is for play, movement, games, and programming. It can be delightful for children and families, but buyers need to be careful about app support, battery condition, accessories, defects, table falls, and warranty.
