Unitree Go2 vs Xiaomi CyberDog 2: Two Budget Quadrupeds for Developers

The Go2 weighs 15 kg, carries up to 8 kg, walks at up to 3.5 m/s and has a 230 Wh battery. The CyberDog 2 is lighter (8.9 kg) and slower (1.6 m/s), and the manufacturer gives no payload in the available material. Both have 12 degrees of freedom and run about 1.5 hours on a battery.

What differs is how each robot is equipped. The Go2 has a 4D LiDAR with a 360°×96° field of view and an HD camera, voice control based on a GPT-type model and gaits trained with reinforcement learning. The CyberDog 2 bets on sensing and compute: a LiDAR, an Intel RealSense D430 depth camera, an RGB camera and 19 sensors in total, plus an NVIDIA Jetson Xavier NX computer (6-core CPU, 384-core GPU, 8 GB RAM, 48 GB storage) running Ubuntu 18.04 and ROS2. CyberGear micro-actuators let it do flips and get up on its own after a fall. The higher Go2 variants, the EDU, also offer a full SDK and ROS2, but cost from about USD 11,190. Ubuntu 18.04, however, is a 2018 release, which is worth considering if your team has its own tooling.

Starting prices are close: the Go2 Air from about USD 1,600, the CyberDog 2 in China CNY 12,999, or about USD 1,800 (about PLN 6,980 (≈ EUR 1,600)). Importers outside China add duty, so a buyer in Europe most often gets a version at USD 1,800–3,000. There is no official distribution in Poland or the EU, and buying one means importing, paying customs duty and 23% VAT, and having no local service.

The Go2 Air costs PLN 9,900–12,000 (≈ EUR 2,260–2,740) here (deltarobots.com, drony.net, Botland, x-kom), the Pro about PLN 21,400 (≈ EUR 4,900) and the EDU Standard PLN 35,900 (≈ EUR 8,210). That is roughly double the US starting price, but with an invoice and local sales. With the CyberDog 2, official support is hard to come by.

For a school and student clubs the Go2 is better: cheap, available, with documentation and a community, and sufficient for first programs. For first steps with code see “How to Start Learning Robotics in Poland”.

The CyberDog 2 suits a university and teams that want a rich vision platform on ROS2 and are ready to handle an import: abundant sensing and a Jetson computer leave more room for your own perception work. The manufacturers aim both robots at similar buyers: the Go2 at consumers, research, education and simple inspection, and the CyberDog 2 at programmers, hobbyists and small research projects. The realistic scenario is a lab bench, a technical show or a programming class, not shift work. If the purchase is to be a one-off with no risk, the Go2 wins on availability; if sensing matters, the CyberDog 2 pays back the trouble of importing. The camera and LiDAR collect data about people around them, so in public institutions check the rules in “Data Security: Robots with Cameras and the GDPR”.
