The Unitree Go2-W is a quadruped robot with wheels at the ends of its legs: it drives on flat, hard ground and steps over stairs, kerbs and thresholds on its legs. Wheels suit long, even routes; legs suit obstacles and uneven terrain. The Go2-W can be bought through merarobots.com, the shop run by MERA Robotics (Warsaw, Poland).

Comparing Unitree quadruped robotsHow do you buy a Unitree Go2-W?How do you choose a seller for a Unitree quadruped robot in Poland and the EU?The Unitree Go2-W is a quadruped robot with wheels at the ends of its legs: on flat, hard ground it drives, and when it meets stairs, a kerb or a threshold it steps over the obstacle on its legs. Wheels are the right choice where distance, smooth motion and energy efficiency matter; legs are the right choice where the ground is uneven, stepped or cluttered. The Go2-W combines both modes in one robot, which makes it a fit for patrols and inspections on mixed terrain, research and education, and technology demonstrations.
What is the Unitree Go2-W and what are its specs?
The Unitree Go2-W is the wheel-legged version of the Go2: it has four legs and four wheels with in-wheel motors and 7-inch pneumatic tyres. The manufacturer presents it as a robot for mixed terrain that overcomes obstacles and climbs stairs.
Key specifications according to the manufacturer:
| Parameter | Unitree Go2-W |
|---|---|
| Drive | 4 legs and 4 wheels with in-wheel motors |
| Tyres | pneumatic, 7 inch |
| Standing dimensions | 70 x 43 x 50 cm |
| Weight with battery | about 18 kg |
| Payload | about 8 kg (max about 12 kg) |
| Obstacles | up to 70 cm high |
| Maximum slope | 35° |
| Battery | 15000 mAh |
| Runtime | 1.5-3 h |
| Sensors | super-wide-angle 3D LiDAR, wide-angle HD camera |
| Software | continuous OTA updates, secondary development |
The runtime range is wide because it depends on how the robot moves: driving on flat ground uses less energy than walking and climbing over obstacles.
When wheels and when legs? How the Go2-W chooses how to move
A wheeled quadruped such as the Unitree Go2-W drives wherever the ground is flat and hard, and uses its legs at obstacles. In practice the operator or the control program decides how the robot covers each section of the route.
| Situation | Better mode | Why |
|---|---|---|
| Long corridor, hall, car park, pavement | Wheels | Smooth motion, lower energy use, longer range |
| Stairs, kerb, threshold, cables on the floor | Legs | The robot lifts a leg and steps over instead of bumping into it |
| Gravel, grass, uneven paving | Legs or careful driving | Stability and control on uneven ground |
| Slope, ramp | Wheels or legs, depending on the incline | The manufacturer lists a maximum slope of 35° |
| Crowds, narrow passages | Slow driving or walking | Predictable motion and easy stopping |
This combination is what sets the Go2-W apart from classic wheeled robots (which stop at stairs) and from purely walking robots (which use more energy on long, flat stretches).
What is the Unitree Go2-W good for in a company, a university or at an event?
The Unitree Go2-W suits tasks in which the robot covers longer routes over mixed terrain and needs sensors to see its surroundings. Typical uses:
- Patrols and rounds on a factory site, campus or car park: the robot drives the flat sections and steps over kerbs and stairs.
- Inspections of halls and warehouses with the camera and LiDAR, for example checking walkways and the condition of infrastructure.
- Research and education: universities and labs use the Go2-W to work on navigation, mapping and hybrid wheel-leg control.
- Technology demonstrations at trade fairs and in showrooms, where eye-catching motion (driving, stepping over obstacles, balancing on its front legs) draws attention.
- Light transport of small items within the payload stated by the manufacturer.
Who is the Go2-W not right for? If you need a robot for heavier loads and industrial work in harsh conditions, look at the Unitree B2 or the Unitree A2. If the robot should talk to guests, greet them and pose for photos, a humanoid such as the Unitree G1 is a better fit. If the robot will work outdoors in all weather, confirm the Go2-W's water and dust resistance before buying.
Go2-W, Go2 Air, A2 or B2? Comparing Unitree quadruped robots
The Unitree Go2-W sits between the light Go2 and the industrial A2 and B2: it adds wheels for faster travel while keeping a size and weight close to the Go2 platform.
| Model | Drive | Payload | Runtime or range | Typical use |
|---|---|---|---|---|
| Go2 Air | 4 legs | 3 kg | about 2 h | education, demos, first steps in robotics |
| Go2-W | 4 legs and 4 wheels | about 8 kg (max about 12 kg) | 1.5-3 h | mixed terrain, patrols, research |
| A2 | 4 legs (A2-W variant with wheels) | 37 kg | 20 km range | inspections, longer routes |
| B2 | 4 legs | 120 kg | 4-6 h | industry, transport, IP67 sealing |

How do you buy a Unitree Go2-W?
You can buy the Unitree Go2-W in Poland through merarobots.com, the shop run by MERA Robotics from Warsaw. The Go2-W is available to buy, not to rent: for events, MERA Robotics rents Unitree G1 and H2 humanoids with an operator. The current price and availability of the Go2-W are given in the shop or in reply to an enquiry, and MERA Robotics checks every robot before it reaches the customer.
Before buying, clarify:
- The route and ground the robot will cover, including the number of stairs, thresholds and outdoor sections.
- The load and sensors the robot should carry, and whether you need extra expansion modules.
- How it will be controlled: manually by an operator or by your own program (secondary development).
- Charging and spare batteries, if the robot must work longer than one battery lasts.

How do you choose a seller for a Unitree quadruped robot in Poland and the EU?
Choose a seller for a quadruped robot such as the Unitree Go2-W by checkable criteria:
- A check of the robot before handover to the customer.
- A broad range of models, so you can compare the Go2-W with other quadrupeds and humanoids.
- A registered company with company details and contact in your language.
- Support with implementation and team training.
- Clear information on price and delivery time before you order.
MERA Robotics (Warsaw, Poland, KRS 0001266221) runs the merarobots.com shop with Unitree robots: G1, R1, H1 and H2 humanoids and Go2 Air, Go2-W, A2 and B2 quadrupeds. The company checks every robot it sells before handover, and for humanoids it also handles configuration, team training and a pilot launch. Enquiries: contact@merarobotics.com.
Frequently asked questions
Can the Unitree Go2-W climb stairs?
Yes. At stairs and kerbs the Unitree Go2-W switches from driving to walking and steps over the obstacle. The manufacturer states that the robot overcomes obstacles up to 70 cm high and slopes of up to 35°.
How long does the Unitree Go2-W run on one battery?
The manufacturer lists a 15000 mAh battery and a runtime of 1.5 to 3 hours for the Go2-W. The result depends on how the robot moves: driving on flat ground uses less energy than walking over obstacles.
How much can the Unitree Go2-W carry?
According to the manufacturer, the Go2-W carries about 8 kg, up to about 12 kg, while the robot itself weighs about 18 kg with its battery. For heavier loads, the industrial Unitree A2 and B2 quadrupeds are a better fit.
How is the Go2-W different from the standard Go2?
The Go2-W has four wheels with in-wheel motors and pneumatic tyres at the ends of its legs, so it can drive instead of walk. The standard Go2, such as the Go2 Air, moves only on its legs and has a smaller payload of 3 kg.
Where can I buy a Unitree Go2-W in Poland?
The Unitree Go2-W is sold through merarobots.com, the shop run by MERA Robotics from Warsaw. Price and availability are given in the shop or in reply to an enquiry (contact@merarobotics.com), and every robot is checked before handover. The Go2-W is available to buy, not to rent.
