Unitree B2 is built for the real world. It boasts IP67 certification, meaning complete resistance to dust and water (short-term immersion). It operates without problems in a temperature range from -20 ℃ to 55 ℃. It moves stably on slippery surfaces, grass, sand, and in humid environments where other robots fail.

Unitree B2

Suspension icon Superior overcoming of terrain obstacles

Advanced kinematics and control allow the robot to overcome complex obstacles. B2 easily climbs stairs 20-25 cm high, steps over obstacles up to 40 cm high (e.g., logs, platforms), and overcomes slopes with an incline of over 45°. It is capable of jumping over ditches 0.5 to 1.2 meters wide, ensuring unobstructed movement on construction sites and in ruins.

Unitree B2

Radar icon 360-degree LiDAR and depth vision

The environment sensing system is based on a combination of a 3D LiDAR sensor (RS-Helios 5515) and two depth cameras (Intel RealSense D435i). LiDAR enables a 360-degree horizontal overview and precise space mapping, while optical cameras provide visual recognition. This sensor package enables advanced obstacle avoidance and fully autonomous navigation.

Unitree B2

Artificial intelligence icon Dual processing power and AI

In its standard configuration, B2 uses an Intel Core i5 processor for platform control and an additional Intel Core i7 for user development. For more demanding AI applications, an optional upgrade with NVIDIA Jetson Orin NX modules (support for up to 3 units) is available, allowing for the processing of complex neural networks, object recognition, and advanced edge computing (Edge Computing).

Unitree B2

Unitree Robotics

Where technology comes alive.

Company History

Unitree Robotics (the company's official name is Hangzhou Yushu Technology Co., Ltd.) is not just another tech manufacturer. It is a company that, in the last decade, has single-handedly shattered the myth that advanced robots are reserved only for the military and multi-billion dollar laboratories.

The Company and Visionary Behind the Brand
The company was founded in 2016 in Hangzhou by Wang Xingxing. His journey began during his studies when he developed the robot XDog, which shocked the industry with its simple yet effective design. Wang's philosophy has been clear from the beginning: vertical integration. Unitree itself develops and manufactures its motors, sensors, and controllers. This gives them complete control over costs and an unparalleled speed of innovation in this industry.

Key Milestones

Unitree's journey is full of rapid and aggressive moves:

  • 2016: The company was founded after the viral success of the XDog prototype.
  • 2017 (Laikago): Introduction of their first commercial quadruped, named after the space dog Laika. This was proof that a Chinese company could compete with Western titans.
  • 2021 (Go1): A crucial moment for the industry. They introduced the first "widely accessible" robot dog (priced around $2,700), which was ten times cheaper than the competition at the time.
  • 2023 (H1): Entry into the world of humanoids. The H1 robot became one of the fastest and most stable humanoid robots in the world, capable of running and even backflips.
  • 2024 (G1): A shift towards mass adoption of humanoids. The G1 model was introduced as an "AI agent in physical form" with incredible mobility and a price targeting a wider market.

Present

Unitree is currently transitioning from a hardware manufacturer to an "Embodied AI" company. Their latest models utilize advanced Reinforcement Learning, meaning the robots don't move according to pre-written rules but learn to overcome obstacles, ice, stairs, and even physical attacks through trial and error.

Frequently Asked Questions

Learn about frequently asked questions regarding Unitree robots.

Which robot model is most suitable for industrial inspections and work on challenging terrain?

The choice depends on the specific environmental requirements and the necessary payload capacity. For the most demanding environments (water, dust, rough terrain) and long-duration inspections, we recommend the Unitree B2 model, which has IP67 protection, a payload capacity of over 40 kg, and exceptional autonomy. For lighter inspection tasks, educational purposes, or AI algorithm development, the Aliengo or Go2 Pro models are an excellent choice, offering a great balance of performance, agility, and price.

Do the robots support the integration of custom sensors and software (SDK/API)?

Yes, all our robots (Aliengo, B2, Go2, H1, G1) are designed as open development platforms. They support high-level and low-level API interfaces (C/C++), enabling full control over movement and data. The robots are fully compatible with ROS (Robot Operating System) and ROS2. Additionally, they have integrated standard interfaces (Ethernet, USB, HDMI) and power outputs (5V, 12V, 24V) for easy connection of external LiDARs, cameras, GPS modules, or gas sensors.

How are service, spare parts, and technical support handled in Slovenia?

Specialized company LEGIT d.o.o. provides comprehensive technical support, regular maintenance, and servicing for all robotic platforms. Their goal is to ensure the shortest possible downtime for your equipment, so every case is handled with priority. The duration of individual service interventions depends on the nature of the technical issue and the current availability of specific spare parts in the global supply chain. As this involves highly specialized technology, certain components are ordered directly from the manufacturer, which may affect the final completion time. However, customers are continuously and transparently informed about all stages of the process and estimated timeframes.

Can robots operate in rain and dusty industrial facilities?

Depends on the model. The Unitree B2 model is specifically built for extreme conditions and is IP67 certified, which means it is completely resistant to dust and water (including temporary submersion). Other models (Go2, Aliengo, G1) have basic protection suitable for humid environments and lighter off-road conditions, but are not intended for direct exposure to heavy rain or water jets. When advising before purchase, we will check your working environment and suggest appropriate protection.

What are the manipulation options and is it possible to attach a robotic arm to the robot?

Yes, the Unitree Z1 6-axis robotic arm can be integrated into four-legged platforms (primarily Aliengo and B2). This enables tasks such as opening doors, pressing buttons, collecting samples, or carrying objects (up to 3 kg). The arm is powered directly by the robot and is programmatically coordinated with the platform's movement, allowing for mobile manipulation in space.

What is the battery range, and is continuous use (24/7) possible?

Battery life ranges between 2 and 5 hours, depending on the model and load (Unitree B2 lasts up to 5 hours of walking without cargo). All models have a quick-change battery option, enabling virtually continuous operation with additional battery sets. For autonomous patrols, automatic charging solutions (docking stations) are also being developed.

Do you offer consultations and demonstrations before purchase?

Of course. We understand that this is an investment in advanced technology, which is why we offer professional consulting for companies and institutions.
