How to Choose, Set Up and Use the Unitree Go2 Robot Dog with 4D LIDAR
Every Unitree Go2 ships with standard 4D Ultra-wide LIDAR and GPT empowerment. Here is how the Pro, Air, and X differ on controller options and what to prepare before setup.

Short answer
The Robot dog for sale: Unitree Go2 with 4D Ultra-wide LIDAR includes the sensor as standard on every version. You choose between Go2 Pro, Air, or X based on whether you want a physical controller. The Pro and Air offer with-controller and without-controller configurations, while the Go2 X always includes one.
What 4D Ultra-wide LIDAR means on the Go2
The 4D Ultra-wide LIDAR is the wide-field sensor that reads the space around the robot, so the machine knows what is near it. This hardware sits in the body as standard on every listed unit. It is not an add-on you buy separately or a higher-tier part reserved for one version.
In practical terms, the LIDAR gives the quadruped proximity awareness. It is the wide-field sensor that reads the space around the robot, so the machine knows what is near it.
Standard hardware across all versions
The 4D Ultra-wide LIDAR comes with the robot on every version (Pro, Air, and X). The hardware is built into the body, not added later.
A quadruped that walks needs to understand what is near it. The LIDAR is standard across all three models, so you do not trade down on spatial awareness by picking a different version.
If you are building out a smart home with other sensors devices, the Go2's LIDAR fits the same logic of giving your home awareness of what is happening in its space. The difference is that this sensor moves with the robot rather than sitting fixed on a wall.
How GPT empowerment shapes interaction
Unitree builds the Go2 with big model GPT empowerment. This puts a large language model behind the way the robot works with you.
Unitree describes the Go2 as a new creature of embodied AI, with the 4D Ultra-wide LIDAR and the GPT model working together in one four-legged body.

The phrase "embodied AI" is key here. Unitree positions the Go2 as a new creature of embodied AI, with the LIDAR and the GPT model working together in one four-legged body.
Comparing the versions: Go2 Pro, Go2 Air, and Go2 X
The three versions share the same standard 4D Ultra-wide LIDAR and the same big model GPT empowerment. The main differentiator affecting your buying decision is the controller. Here is how the controller options break down across the lineup.
| Version | Controller options |
|---|---|
| Go2 Pro | Sold with or without a controller |
| Go2 Air | Sold with or without a controller |
| Go2 X | Controller included |
The Go2 Pro and Go2 Air each come in two configurations. You can buy either one bundled with a physical controller, or you can buy it without one. The Go2 X ships with a controller in the box, with no without-controller option to weigh.
This setup lets you match the machine to how you plan to drive it. The without-controller configuration on the Pro or Air means you are not buying a controller you will not use. If you want a dedicated physical controller, the with-controller version of the Pro or Air, or the Go2 X, is the path.
When you view the Robot dog for sale: Unitree Go2 with 4D Ultra-wide LIDAR on the product page, the version you pick determines what comes in the box alongside the robot itself. The robot's core sensing and AI capabilities remain the same.
The role of embodied AI in daily use
Unitree calls the Go2 a new creature of embodied AI. The 4D Ultra-wide LIDAR and the GPT model work together in one four-legged body, and that combination defines the daily experience of living with the robot.
This differs from a smart speaker that hears you but cannot move, or a fixed camera that sees the room but cannot walk over to something. The Go2's design puts sensing, language processing, and locomotion in one machine. That is what Unitree means by a new creature of embodied AI: the intelligence is in the body, and the body is part of how that intelligence operates.
Think of the Go2 as a single quadruped robot to live with or work on. The LIDAR and GPT are not separate features you toggle between. They run together in the same body, and that integration produces the robot's behaviour. You are buying one machine, not a collection of modules.
Setting expectations for setup
Setting up a quadruped robot comes down to preparing the space and understanding what the robot needs to operate safely. Clearer pathways in your home are a sensible start.
What to prepare before your Go2 arrives
- Clear floor clutter from rooms where the robot will walk, so the LIDAR has clean readings of the space.
- Remove loose cables, low obstacles, and items on the floor that a quadruped might step on or trip over.
- Decide which rooms the robot will operate in and which areas you want to keep off-limits.
- Plan where you will store the controller if you buy a version that includes one, so it is easy to find when you want it.
- If you have pets, think about how they will share space with a walking robot and supervise early interactions.
The 4D Ultra-wide LIDAR is built into the body as standard and requires no separate installation. The sensor is there from the start on every Go2.
The Go2 is a walking device, so the environment you need to prepare is the floor it moves across.
What helps the Go2 work well at home
- Open floor areas where the LIDAR can read the space without dense clutter.
- Consistent pathways between rooms the robot will move through.
- A controller stored in a known place if your version includes one.
What to watch for
- Pets or children sharing space with a walking robot for the first time.
Safety is the main priority. A quadruped robot moves through the same space you do. Start in a clear room and expand from there.
Which Go2 version fits your plan
If you want a physical controller in your hand, any of the three versions can deliver that. The Go2 X includes one. The Go2 Pro and Go2 Air offer it as a bundled option. Pick the version that matches how you want to drive the robot, and remember that the core hardware, the 4D Ultra-wide LIDAR and the GPT empowerment, is the same across the board.
If you do not want a dedicated controller, the without-controller configuration of the Pro or Air is the route. You get the same robot, the same sensor, and the same AI, without a piece of hardware you would leave in a drawer.
For a first quadruped purchase, the practical question is simple: do you want a controller included? Answer that, and the version decision follows from it.
If you are building a broader smart-home setup, the Go2 can sit alongside other pet tech devices and automation hardware as the piece that moves, senses, and responds in physical space. It is the device in the setup that does not stay put.
FAQ
- Does every Unitree Go2 include the 4D Ultra-wide LIDAR?
- Yes. Every Go2 listed carries the 4D Ultra-wide LIDAR as standard. The hardware sits in the body on the Pro, Air, and X alike, and it is not something you add later or upgrade to.
- Which Go2 versions come with a controller?
- The Go2 X includes a controller. The Go2 Pro and Go2 Air are each sold in a with-controller version and a without-controller version, so you choose based on how you plan to drive the robot.
- What does big model GPT empowerment mean on the Go2?
- Unitree builds the Go2 with big model GPT empowerment, which puts a large language model behind the way the robot works with you.
- Why does Unitree call the Go2 a new creature of embodied AI?
- Unitree describes the Go2 as a new creature of embodied AI because the 4D Ultra-wide LIDAR and the GPT model work together inside one four-legged body. The intelligence is in the robot, and the robot's body is part of how that intelligence operates.
- Do I need to buy the LIDAR separately for the Go2?
- No. The 4D Ultra-wide LIDAR comes with the robot as standard on every version. The hardware is built into the body, not sold as an add-on or a higher-tier option.
