The Xiaomi CyberDog 2 is a consumer-grade quadruped robot dog designed by Xiaomi to serve as both a research platform and a robotic pet companion. It weighs just 8.9 kg (19.6 lbs), stands about 36.7 cm tall, features 12 degrees of freedom powered by Xiaomi's proprietary CyberGear micro-actuators, and packs 19 high-precision sensors including LiDAR, an Intel RealSense D430 depth camera, and a 13 MP AI interactive camera. Originally priced at ¥12,999 (~$1,800) in China and approximately $3,000 internationally, CyberDog 2 is roughly 40% lighter and 16% smaller than its predecessor while performing significantly more complex maneuvers — including continuous backflips, front flips, skateboarding, and moonwalking. It runs on Ubuntu 18.04 + ROS2 and is open-source, making it both a striking consumer product and a legitimate development platform.
Price Range
CyberDog 2 was launched in August 2023. Pricing varies significantly between the Chinese domestic market and international resellers.
| Market | Price (Low) | Price (Average) | Price (High) |
|---|---|---|---|
| China (official) | ¥12,999 (~$1,800) | ¥12,999 (~$1,800) | ¥12,999 (~$1,800) |
| International (Giztop, resellers) | $1,800 | $2,500 | $3,000 |
| eBay / secondary market | $2,000 | $2,800 | $3,500 |
Based on publicly listed prices from Giztop, AwesomeRobots, eBay, and Chinese retail as of April 2026. International availability is limited — most purchases go through specialized importers. The remote controller is sold separately.
Important: Language limitation. CyberDog 2's built-in XiaoAI voice assistant supports Chinese only. App and graphical programming interfaces are available in English, but voice interaction is currently limited to Chinese-language commands.

CyberDog 2 traded some speed and payload for dramatically lighter weight, more sensors, better agility, and a more polished consumer design. The original CyberDog was faster and stronger but heavier and more industrial-looking.
Buyer's Guide: What to Know Before Buying a Xiaomi CyberDog 2
International Availability Is Limited
CyberDog 2 launched in China and is primarily sold through Chinese retail channels. International buyers typically purchase through importers like Giztop or eBay resellers, often at a premium. There is no official Xiaomi global sales channel for CyberDog 2. Expect potential issues with warranty, support, and customs.
Voice Control Is Chinese-Only
XiaoAI voice assistant only understands Chinese. If you plan to use voice commands in English, this is a significant limitation. The mobile app and graphical programming interface work in English, but voice interaction does not.
Payload Is Just 1 kg
CyberDog 2 carries far less than the Unitree Go2 (up to 10 kg on the Pro). At 1 kg, you can mount a small camera or light sensor — not much else. If payload capacity matters for your use case, the Go2 is the better choice.
Speed Is Lower Than CyberDog 1
At 1.6 m/s max (vs the original CyberDog's 3.2 m/s), CyberDog 2 is noticeably slower. The trade-off was weight reduction and improved agility. If speed matters, consider the Go2 Pro (3.5 m/s) or Go2 X (3.7 m/s).
It Is a Legitimate Development Platform
Running Ubuntu 18.04 + ROS2 on an NVIDIA Jetson Xavier NX with 384 CUDA cores and 3 USB-C ports, CyberDog 2 is genuinely open-source and developer-friendly. Xiaomi provides structural drawings, graphical programming tools, and modular sensor processing. For robotics students and developers in the Xiaomi ecosystem, it's a capable platform.
Battery Life Is 90 Minutes
Identical runtime to Boston Dynamics Spot and competitive with the Unitree Go2's standard 8,000 mAh battery (1–2 hours). Adequate for lab sessions and demonstrations, but not for extended outdoor use without spare batteries.
It's Beautiful but Fragile
The Doberman-inspired bionic design is striking, and the 9 removable shell panels allow full visual customization. But at 8.9 kg with 1 kg payload capacity, CyberDog 2 is built for agility demonstrations and indoor companionship — not rugged outdoor work.
Xiaomi CyberDog 2 vs Similar Robots
- CyberDog 2 vs Unitree Go2 Air: The Go2 Air ($1,600) is cheaper, heavier (15 kg vs 8.9 kg), carries much more payload (7 kg vs 1 kg), has a 4D LiDAR with 360° × 96° FOV, and runs faster (2.5 m/s). CyberDog 2 has more sensors (19 vs Go2 Air's sensor suite), an NVIDIA Jetson Xavier NX (vs Go2 Air's 8-core CPU), and 3D-printable customizable shells. The Go2 is the better practical robot; CyberDog 2 is the flashier consumer product.
- CyberDog 2 vs Unitree Go2 Pro: The Go2 Pro ($2,800) has GPT-powered voice interaction (in English), 4G cellular, side-follow mode, 3.5 m/s speed, and 10 kg payload — all areas where it substantially outperforms CyberDog 2. CyberDog 2 has Xiaomi smart home integration and the Jetson Xavier NX compute module. For most buyers outside China, the Go2 Pro is the stronger choice.
- CyberDog 2 vs Unitree Go2 EDU: The Go2 EDU ($11,200+) adds an NVIDIA Jetson Orin (40 TOPS), extended battery, depth cameras, foot force sensors, and full Python/ROS SDK. CyberDog 2 already includes a Jetson Xavier NX and ROS2 at a much lower price point. For budget-constrained developers who want NVIDIA compute + ROS2 out of the box, CyberDog 2 offers strong value — if you can work around the Chinese-language voice limitations.
- CyberDog 2 vs Boston Dynamics Spot: Entirely different categories. Spot ($74,500) is an industrial inspection platform with IP54, 14 kg payload, enterprise software, and 1,500+ commercial deployments. CyberDog 2 ($1,800–$3,000) is a consumer/research robot pet. No overlap in buyer or use case.
- CyberDog 2 vs CyberDog 1: CyberDog 2 is 40% lighter, 16% smaller, has 19 sensors (vs 11), 2× motor precision, and dramatically improved agility. CyberDog 1 was faster (3.2 m/s) and carried more (3 kg). CyberDog 2 is the better consumer product; CyberDog 1 was the better raw performer.
