Unitree Z1 - Compact 6-axis Robotic Arm

High-precision and lightweight manipulation system for mobile platforms and industrial automation.


Unitree Z1

Industry icon Which industrial and research applications is this robot suitable for?

Unitree Z1 is designed for a wide range of tasks where mobility and precision are key. In logistics and warehouses, it enables "pick-and-place" operations on mobile platforms. In industrial production, it serves for the assembly of lightweight components and machine tending. Due to its open architecture, it is indispensable in research institutes for developing manipulation algorithms and in "New Retail" scenarios for automated service and customer interaction.

Unitree Z1

Modes icon Perfect synergy with mobile robots

The Z1 is not just a static arm; it was developed specifically for integration onto quadruped robots (such as Unitree Aliengo and B1) and other mobile vehicles (AGV/AMR). With its compact design and standardized interface, it allows mobile robots to not only observe but physically interact with the environment – opening doors, pressing buttons, or carrying cargo on challenging terrain.

Unitree Z1

Motor icon 6 degrees of freedom and harmonic drives

The robotic arm boasts 6 degrees of freedom (6 DOF), allowing it exceptional flexibility and reach from various angles. Each joint uses high-precision harmonic reducers and industrial cross-roller bearings. This ensures smooth movement, high torque (up to 33 N·m at the base), and minimal backlash (~6 arcmin), which is crucial for precise operations.

Unitree Z1

Protection icon Safety and collision detection

For safe collaboration between humans and robots (collaborative work), the Z1 is equipped with a collision detection system. Advanced algorithms and torque feedback allow the arm to stop immediately or adjust force in case of unexpected contact. Support for "Joint Force Control" ensures force control precision up to ~0.2 N·m, protecting both the robot and its surroundings.

Unitree Z1

Weight icon Weight-to-payload ratio

Unitree Z1 stands out for its lightweight construction. The arm itself weighs only about 4.3 kg (depending on the version), yet it provides an impressive payload capacity. The Z1 Air version lifts up to 2 kg, while the more powerful Z1 Pro version handles loads up to 3 kg (even more under certain conditions). This favorable ratio is ideal for mounting on smaller mobile platforms where every kilogram matters.

Unitree Z1

Rocket icon Speed and movement dynamics

Despite its compact size, the Z1 is an extremely agile device. The maximum joint rotation speed reaches up to 180°/s, enabling fast cycle times in production processes. The arm can perform complex movements within its working range (740 mm reach) with high repeatability (~0.1 mm), ensuring consistency in repetitive tasks.

Unitree Z1

Programming icon Open source development and API

Unitree Z1 is a true platform for developers ("Open Programming Interface"). It supports programming in C++ and is fully compatible with ROS (Robot Operating System). Users have access to low-level and high-level commands, including torque, position, and speed control for each individual joint, enabling the development of custom kinematics and control solutions.

Unitree Z1

Bluetooth icon Connectivity and tool changing

The end of the arm (flange) allows for quick changes of various effectors – from electric grippers and suction cups to screwdrivers and cameras. The arm communicates via a reliable Ethernet interface and uses RS485 for internal communication. It is powered by a standard 24V source, facilitating integration into existing industrial systems.

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. Based on your needs, we help you choose the right model and configuration of additional equipment.
