Go2
The Go2 is Unitree's compact quadruped, supplied as a development platform. Unitree's control stack handles locomotion; you write your application against it over the robot's internal network, wired for anything touching low-level control.
This page does not repeat or replace Unitree's documentation. It highlights the information you reach for most often, and supplements it with what we have learned from supplying and supporting these units — configuration, verified values, and our own guides.
Unitree's own documentation:
Getting started
Read Operational Safety before powering the robot for the first time, including the additional hazards specific to quadrupeds.
The Go2 Edu we supply carries Unitree's 4D LIDAR L1 and, where fitted, the expansion dock that gives you a computer of your own to work on. Bring-up in outline:
- Power on and pair the controller or the mobile app.
- Connect your machine to the robot's internal network over Ethernet.
- SSH to the expansion dock — see Logins and IP addresses.
- Install the SDK and run one of Unitree's examples.
Then see Guides for this product for diagnostics and SLAM.
Key information
A quick reference for the things you reach for most often, collected so you can find them with the robot in front of you. Values are as configured on the units we supply.

Serial number
The serial number and model designation are in the battery compartment, and in the mobile app under Device → Robot Settings. The app is usually faster and gives you both at once.
Logins and IP addresses
| Computer | Address | Credentials | What it is |
|---|---|---|---|
| Expansion dock | 192.168.123.18 | unitree / 123 | Where your code runs |
| Operation & control | 192.168.123.161 | — | Unitree's control stack. Not user-accessible |
The expansion dock module is not compatible with the Go2 Air or Go2 Pro. Without it there is no user-accessible computer on the robot, and development happens from an external machine over the SDK.
Use a wired connection for anything touching low-level control — WiFi dropouts can stall a control loop and drop the robot. WiFi is reasonable for high-level work and for internet access.
Network layout
The control computer and the expansion dock sit on the robot's internal 192.168.123.x network. Your code goes on the expansion dock.

Troubleshooting & FAQ
What does "account insufficient" mean?
Each new Go2 comes with a complimentary RMB 120 credit, used for data transfer and GPT services. Consult the Connection Mode table to see which connection modes consume it. When the balance runs out, the Go2 can only be connected in AP mode.
To top it up, contact us.
Does the Go2 support 4G?
Yes — insert a SIM card into the slot.
Why does the robot suddenly enter damping mode?
The motors have overheated, and damping mode is protective. Avoid holding the locked stand mode for extended periods — that is the most common cause.
Does the robot have a follow-me function?
Yes. See Unitree's UWB application guide and the accompanying-mode video on the official product page.
Can I develop over WiFi instead of a wired connection?
Technically yes, and it is fine for high-level work. Not for low-level control — a WiFi latency spike or dropout can stall the control loop and the Go2 can fall as a result. Use a cable for anything joint-level or balance-related. See the full answer.
Questions that apply across our platforms
These are answered in the guides rather than repeated on every product page:
- Is the robot waterproof? — no, and what the ratings mean across platforms
- How often do I need to lubricate the joints? — and what to do about stiffness or play
- The robot has fallen over and does not respond to the controller — the recovery sequence
