Načini ikona 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 ikona 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

Zaščita ikona 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.

FAQs

Get familiar with frequently asked questions regarding UNITREE robots.

Which robot model is best suited for industrial inspections and work on demanding terrain?

The choice depends on the specific environment and payload requirements. For the most demanding environments (water, dust, heavy terrain) and long-duration inspections, we recommend the Unitree B2 model, which features an IP67 rating, a payload capacity of over 40 kg, and exceptional autonomy. For lighter inspection tasks, research, or the development of AI algorithms, the AlienGo or Go2 models are excellent choices, offering a great balance of performance, agility, and price.

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

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

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

The specialized company LEGIT d.o.o. is responsible for overall technical support, regular maintenance, and servicing of these robotic platforms. Their goal is to ensure the shortest possible downtime for the equipment, which is a top priority for every customer. The duration of an individual service intervention depends on the nature of the technical issue and the current availability of specific spare parts in the global supply chain. Since this involves highly specialized technology, some components are sent directly to the manufacturer, which can prolong the repair time; however, customers are kept transparently informed of all steps and estimated timeframes throughout the process.

Can the robots operate in rain and dusty industrial plants?

It depends on the model. The Unitree B2 model is specifically built for extreme conditions and has an IP67 certificate, meaning it is resistant to dust and water (including short-term immersion). Other models (Go2, AlienGo, G1) have basic protection suitable for outdoor environments and easier field conditions but are not intended for direct exposure to heavy rain or water jets. Before purchase, we recommend checking your working environment so we can suggest the appropriate protection.

What are the possibilities for manipulation, and is it possible to mount a robotic arm on the robot?

Yes, on the larger platforms (primarily AlienGo and B2), it is possible to integrate the 6-axis Unitree Z1 robotic arm. This enables the execution of tasks such as opening doors, pressing buttons, collecting samples, or moving objects (up to 3 kg). The arm is powered directly from the robot and is programmatically integrated with the platform's movement, enabling mobile manipulation in space.

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

Autonomy ranges between 2 and 5 hours, depending on the model and load (the Unitree B2 lasts up to 5 hours without a load). All models feature a fast battery replacement option, which enables practically uninterrupted operation with the use of additional battery sets. For autonomous patrols, automatic charging solutions (docking stations) are also being developed.

Do you offer the possibility of consultation and a demonstration of operation before purchase?

Of course. We understand that this is an investment in advanced technology, so we offer expert advice for companies and institutions. Based on your needs, we help you choose the right model and hardware configuration. For those interested, we can also organize a live demonstration of the robots' capabilities at our location or on your terrain by agreement.

Unitree Robotics

"When technology comes to life."

Company History

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

The company and the 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 XDog robot, which shocked the industry with its simple but effective design. Wang's philosophy was clear from the start: vertical integration. Unitree develops and manufactures its own motors, sensors, and controllers. This allows them full control over costs and the speed of innovation, which is unprecedented in this industry.

Key Milestones

Unitree's path is full of fast and aggressive moves:

  • 2016: Foundation of the company following the viral success of the XDog prototype.
  • 2017 (Laikago): Presentation 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 key moment for the industry. They introduced the first "widely accessible" robot dog (priced at 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 backflipping.
  • 2024 (G1): Move towards mass adoption of humanoids. The G1 model was introduced as an "AI agent in physical form" with incredible mobility and a price point aimed at the wider market.

Present Day

Unitree is currently in a transition phase from a hardware manufacturer to an "Embodied AI" (embodied artificial intelligence) company. Their latest models use advanced machine learning (Reinforcement Learning), meaning that the robots do not move according to pre-written rules, but instead learn through trial and error to overcome obstacles, ice, stairs, and even physical attacks.
