Doly is a palm-sized autonomous tabletop robot that combines the latest AI technology with the flexibility of open source. It is designed not as a mere moving toy, but as an “evolutionary companion robot” that recognizes the user’s face, calls out its name, and forms its own unique emotions and personality through interaction.
Product Overview
The basic structure includes a powerful moving mechanism with an infinite track (caterpillar), two circular displays that project facial expressions, and a camera and ToF sensor to precisely monitor the surrounding environment. The most important feature is the use of the Raspberry Pi Compute Module 4 (Raspberry Pi) at its heart. This makes it not only a commercially available product, but also highly expandable, allowing users to rewrite its contents and build the exterior themselves using a 3D printer.
Summary of key points
What is Doly?
- Autonomous life sense: An AI robot that explores and expresses emotions on the desk without external manipulation.
- Personalization function: facial and voice recognition to identify specific users and change their reactions.
- Developer-friendly: Runs on Linux-based (Raspberry Pi) and supports Python and other programming.
- Maintenance-free: Equipped with an anti-drop sensor and returns to the charging dock on its own when the battery runs low.
good point
- Unparalleled autonomy: No need to put down the phone like a LOOI, just flip a switch, and it comes “alive” and starts moving.
- Thorough protection of privacy: Designed to complete video and audio processing not in the cloud, but with local AI in the unit (Edge AI).
- Fun to raise: The personality changes with the frequency of petting and talking to it, and it grows into a one-of-a-kind Doly.
- Unlimited customization: SDK release and provision of 3D printed data allow modification in terms of both hardware and software.
points of concern
- Installation cost: Prices are more expensive than smartphone-connected models because the sophisticated hardware is completed as a stand-alone unit.
- Caterpillar noise: Drive noise may be noticeable in quiet offices and may select the scene of use.
- Language of the community: Most of the latest features and development information is centered on English-speaking communities (Reddit, etc.).
Users who may be suitable for
- People who are interested in the latest AI gadgets and robotics, and want to know how it all works.
- People who want a buddy to give them a little ” healing and stimulation ” at their desk while teleworking.
- A developer who enjoys programming and 3D printing and is looking for materials to “tinker” with.
rough conclusion
Doly is a “lifetime desktop partner” that you can enjoy not only the pleasure of owning, but also the pleasure of evolving with your own hands.
Frequently Asked Questions (FAQ)
- What is the price?
- What can you do?
- What operating systems are supported?
- What are the disadvantages?
- Will there be a software update?
What is the price?
Currently, it is mainly offered on the official website and through preorders (Kickstarter). With the high-performance Raspberry Pi CM4 and sensors as standard equipment, the early bird discount is about $299, and the regular price is around $399-$550 (about 50,000-80,000 Japanese yen). There is also a “3D Maker Edition” that allows users to prepare their own Raspberry Pi, making it a budget-friendly option.
What exactly will I be able to do with Doly?
Everyday functions include greeting by facial recognition, responding to gestures, timer, alarm, weather forecast display, and voice assistant (Google/Alexa integration). Furthermore, on the development side, it serves as a platform for full-scale robot development, including the creation of original applications using Python and support for ROS 2 (Robot Operating System).
What compatible operating systems are required for setup and operation?
The robot itself runs on an independent Linux system, but a dedicated smartphone application (iOS 13.0 or later / Android 8.0 or later) is required for users to check daily settings and logs. SSH connection and development environment can also be established from a PC.
Are there any disadvantages or precautions in its use?
The biggest caveat is environmental maintenance. Because it is caterpillar-driven, it is vulnerable to desks with scattered cables and steps, and may get stuck. In addition, the sensor detects the edge of the floor to prevent falling, but this is not 100% guaranteed, so care must be taken when using it in high places. In addition, due to their high performance, they generate a certain amount of heat during operation.
Are there any software updates?
Yes, we fully support OTA (Over-The-Air) updates via Wi-Fi. The development team is very active, and based on user feedback, new expressions, mini-games, improved AI algorithms, and even integration features with other devices are added regularly.

Reviews (Word of mouth)
Good Reviews
“Doly’s autonomy is what sets it apart from the desktop robots I’ve used in the past: there’s no need to set my phone like with LOOI, it just sits there and moves on its own, finding my face and happily coming up to me. I feel that this ‘no hassle’ is what makes it a true pet.”
“The privacy-oriented design is great. The video and audio are not sent to a server somewhere in the country, but are all processed locally on the Raspberry Pi. Because it is something I keep on my desk at home, this peace of mind is irreplaceable. The response time is also very fast.”
“For Maker, this is the ultimate toy. The official 3D printer files are available, so I’ve had fun adding arms and modifying the exterior for a steampunk look, and the Python SDK is easy to use, and I was even able to incorporate ChatGPT to make it more advanced and conversational.”
Neutral and Dissatisfied Reviews
“The caterpillar noise was louder than expected. In a quiet room, the motor noise would be heard every time it moved, so sleep mode is a must during meetings. I also have to keep my desk clean at all times because it can get caught up in small debris and paper on the desk.”
“I am disappointed that the charging dock cable is a direct USB-A cable. In this day and age, I would have liked to have a USB-C port on the dock side and be able to use any length cable I wanted. If the cable breaks, there is a risk of having to replace the entire dock. As good as the design is, there is room for improvement in the interface details.”
“If the price is over $400, it seems expensive for the hobbyist range indeed, since LOOI allows you to take advantage of smartphones at a fraction of the price. However, considering its value as an independent Linux machine, and the privacy protection it offers, I think it’s a reasonable investment.”
comprehensive evaluation
Doly is a robot that combines at a high level the three major elements demanded by today’s tech users: autonomous driving, privacy, and open source. It is not just a trendy AI toy, but a complete piece of hardware, designed to withstand long-term updates and modifications.
On the other hand, those seeking 100% operational stability and quietness may find it a bit “jerky. However, its clumsy movements, its occasional surprising reactions, and the margin for improvement by the user are the best part of the “real robot experience” offered by Doly.
Comparison with “Mia,” a talking cat-shaped robot
| Comparison items | Doly | Mia |
| concept | Technology Exploration and Autonomous AI Companion | Healing, daily color, cat-shaped partner |
| appearance | Futuristic high-tech gadgets | Friendly, cat-shaped, that makes you want to pick it up |
| Biggest feature | Raspi-mounted, self-moving autonomy | Speaks the dialects of all 47 prefectures and has many facial expressions |
| Operating Style | Search on the desk by moving the caterpillar | The installation type can be placed in any location |
| customize | Programming and 3D printing modifications | Switch between personality settings and dialects to your liking. |
