Robot dog Unitree As2 X

Intelligent Robo-Dog Unitree As2 X for R&D and Industrial Tasks

Unitree As2 X is a lightweight robo-dog weighing 18 kg, designed for universities, R&D labs, and companies to test algorithms for autonomous walking, patrolling, logistics, or secondary development through SDK and Isaac Sim simulator. The model is made of aluminum alloy and durable plastic with IP54 protection for stable operation at temperatures from -20 °C to +50 °C. With 12 degrees of freedom and synchronous PMSM motors with a torque of 90 Nm, the device reaches speeds of up to 5 m/s, overcomes slopes up to 40°, and steps up to 25 cm. A removable lithium battery with a capacity of 15000 mAh guarantees over 4 hours of autonomy up to 20 km without load or up to 2.5 hours up to 13 km with useful equipment weighing 15 kg, while the maximum static stability reaches 65 kg.

Engineering and Operational Advantages of Unitree As2 X

• Advanced base for Embodied AI and learning. The platform is designed as a flexible tool for practicing scenarios of autonomous movement, mechatronics, robotic vision, and navigation in complex environments.
• Development capabilities (SDK). Engineers have access to a complete package of accompanying documentation, simulation interfaces, 3D models of the robot, and ready integration tools, including support for the Isaac Sim environment.
• Operating time for long missions. The lithium battery with a capacity of 15000 mAh operates for more than 4 hours of movement without load, allowing a distance of up to 20 km.
• Transporting physical loads. The robot transports equipment weighing up to 15 kg while walking, with a maximum static support stability of 65 kg.
• High obstacle passability. The leg design allows climbing slopes at an angle of 40 degrees, bypassing barriers, and stepping on stairs up to 25 cm high.
• Lightweight metal construction. The body is made of aluminum alloy and durable plastic, reducing the overall weight while maintaining resistance to mechanical impacts.
• Sealing according to IP54 standard. The shell isolates internal circuits and wires from fine dust and water splashes during outdoor testing in any weather.
• Wireless communication and sensors. The device has Wi-Fi 6, Bluetooth 5.2 modules, an HD camera, microphones, a speaker, and signal LEDs. GPS and 4G LTE data transmission channels are enabled only with the owner's consent.
• Terrain scanning with LiDAR. Robotic vision is enhanced by a laser LiDAR scanner with 64–128 lines for fast 3D mapping of the environment.

Kinematics and Speed Indicators of Unitree As2 X

The robo-dog design has 12 degrees of freedom. Movement is provided by low-inertia synchronous PMSM motors with an internal rotor, which quickly dissipate heat and instantly read commands. Each joint is equipped with dual encoders for precise positioning control and industrial cross roller bearings designed for high radial and axial loads.

The leg rotation amplitude ranges from -115° to +200° for the hip and from -159° to -47° for the shin. The maximum rotational torque of 90 Nm helps the device maintain balance on ice or sand, run in narrow passages, and reach speeds of up to 5 m/s.

Battery Characteristics and Range

For extended patrolling, inspections, and logistics, the Unitree As2 X is equipped with a lithium battery with a capacity of 15000 mAh, operating at a voltage from 36 to 50.4 V.

• Autonomy without additional weight: over 4 hours of continuous walking or up to 20 km distance.
• Operating time with equipment weighing 15 kg: about 2.5 hours of walking or up to 13 km distance.

The included express charging device at 51 V and 9 A restores the battery capacity in a short time, minimizing forced stops during testing.

Module Connection and Customization of Unitree As2 X

The sturdy body and high static load capacity up to 65 kg, dynamic up to 15 kg, make the Unitree As2 X robo-dog a ready platform for installing third-party sensors. The device's back features engineering ports for quick equipment installation: a gigabit Ethernet connector, SBUS port x1, and direct power output from the BAT battery.

Thanks to these interfaces, engineers can install additional computing boards such as NVIDIA Jetson Orin Nano modules at 40 TOPS, 3D depth cameras, gas analyzers, lightweight manipulators, or industrial sensors. Electronics and mechanical components work stably outdoors within temperature ranges from -20 °C to +50 °C.

Practical Recommendations

• Task Configuration: clearly define the target purpose of Unitree As2 X at the initial stage (e.g., simulation modeling, autonomous patrolling using LiDAR maps, or transporting physical loads).
• Expanding the Perception System: if missions are planned in spaces with complex geometry and small obstacles, it is recommended to equip the robot with a depth 3D camera and Jetson Orin Nano computing platform.
• Equipment Weight Calculation: during the integration of own equipment (cameras, sensors, manipulators), ensure that the total weight of third-party modules does not exceed 15 kg, otherwise, the robot's autonomy and maneuverability indicators will begin to decrease.
• Working in Extreme Conditions: despite IP54 protection, avoid prolonged immersion of the robot in water or operation in heavy rain. Always check the cleanliness of the LiDAR scanner's protective glass before autonomous launch.
• Testing in a Virtual Environment: before deploying new patches or experimental movement algorithms on real hardware, always conduct preliminary code verification in the Isaac Sim simulation environment to protect the robot's mechanics from falls and damage.
