Built for precision and smooth robotic motion

The UNITREE Z1 Pro combines compact dimensions with impressive performance, making it ideal for projects where accuracy and mobility matter. Its 6-axis design gives the arm the flexibility needed for complex manipulation tasks, while repeatability of around 0.1 mm helps ensure consistent results. Thanks to joint speeds of up to 180°/s, the arm can handle both dynamic movement and detail-focused operations.

Wide range of motion for demanding tasks

Each of the six joints offers a generous working range, allowing the arm to move naturally through complex trajectories and operate effectively even in tighter spaces. Joint ranges include J1 at ±150°, J2 from 0° to 180°, J3 from −165° to 0°, J4 at ±80°, J5 at ±85°, and J6 at ±160°. This gives users plenty of freedom for tool positioning, obstacle avoidance, and advanced robotic workflows.

Strong payload in a lightweight form

With a payload capacity of at least 3 kg, the UNITREE Z1 Pro can work with a wide range of end-effectors, tools, and custom attachments. Its low arm weight of approximately 4.5 kg makes it especially attractive for portable setups, benchtop robotics, experimental stations, and integration with mobile robotic platforms. This balance of strength and low weight opens up plenty of possibilities for creative and technical builds alike.

Advanced control and safer interaction

The arm supports position control as well as force and torque control, making it suitable for more advanced applications that require responsive contact with the environment. Built-in collision detection and force feedback help improve operational safety and enable more sensitive manipulation tasks. Ethernet communication and an Ubuntu-based user environment also make the system easier to integrate into existing robotics workflows.

Ready for development, testing, and integration

The UNITREE Z1 Pro is well suited for ambitious robotics projects thanks to support for SDK tools, ROS, and simulation environments such as Gazebo. This makes it easier to develop motion algorithms, test automation concepts, connect vision systems, and build complete mobile or stationary robotic solutions. Whether you are experimenting, prototyping, or refining a hobby robotics setup, this arm offers a strong technical foundation.

UNITREE Z1 gripper - the perfect finishing touch

The dedicated UNITREE Z1 gripper is designed specifically for the Z1 arm and expands its capabilities with reliable object handling. Lightweight yet durable, it is optimized to avoid overloading the arm while still delivering a secure and adaptable grip on objects of different shapes and sizes. It is an essential accessory for users who want to turn the robotic arm into a complete manipulation tool for interactive and practical tasks.
