Robot dog Unitree A2 Pro

Unitree A2 Pro Robot Dog for Inspection, Logistics, and Field Tasks

Unitree A2 Pro is a robot dog designed for enterprises, R&D laboratories, and technical control services to perform inspections, logistical tasks, and field engineering missions. The model is equipped with two LiDAR scanners and an HD camera, allowing it to confidently navigate technical areas, warehouses, open sites, stairs with a step height of up to 30 cm, and slopes with an angle of up to 45°. The device weighs 37 kg with batteries, has 12 joint motors with a peak torque of 180 Nm, is protected by IP56–IP67 standards, and supports full secondary development based on an embedded Intel Core i7 computer. A dual-slot power system with hot-swappable batteries with a total capacity of 18,000 mAh provides over 5 hours of autonomy without load or more than 3 hours of stable operation with useful equipment weighing up to 25 kg, while the maximum support stability of the device in place reaches 100 kg.

Main Advantages of Unitree A2 Pro

• Working with a Load. Unitree A2 Pro can carry up to 25 kg while walking, and the maximum static load in a standing position is about 100 kg. This allows for the installation of sensors, cameras, communication modules, computing units, data collection devices, or test equipment for industrial inspection and logistics routes.
• Two Hot-Swappable Batteries. The robot has two battery compartments, and one battery has a capacity of 9000 mAh, or 453.6 Wh. Two batteries provide a total of 18,000 mAh, or 907.2 Wh, and hot-swap support reduces pauses between work cycles.
• Long Routes with and without Load. Without a payload, the A2 Pro operates for over 5 hours and covers approximately 20 km. With a 25 kg load, it is claimed to operate for over 3 hours and cover a route of about 12.5 km, making the robot suitable for logistics for long tests in warehouses, production sites, and ranges.
• Two LiDARs for Spatial Perception. The A2 Pro version has LiDAR at the front and rear, an HD camera, and front light. This configuration helps the robot read obstacles, collect data for mapping, move through technical passages, and work indoors or in open areas.
• Mechanics for Uneven Surfaces. The robot dog has 12 degrees of freedom, joint motors with a maximum torque of about 180 Nm, and industrial cross-roller bearings. Thanks to this, the platform can move up stairs up to 30 cm, slopes of about 45°, and routes where wheeled vehicles find it difficult to maintain passability.
• Protected Body for Field Conditions. The body is made of aluminum alloy and high-strength engineering plastic. The A2 Pro is rated IP56–IP67, and the main components are rated IP67 depending on the configuration, which is important for dust, splashes, moisture, and work outside clean laboratory conditions.
• Interfaces for Additional Equipment. Unitree A2 Pro has RS485 x2, CAN x2, Gigabit Ethernet x2, USB 3.0 Type-C x4, and power outputs of 12 V / 24 V / BAT. Through these ports, external sensors, controllers, cameras, computing modules, and equipment for applied tests can be connected.
• Platform for Secondary Development. The standard configuration includes an 8-core platform processor and Intel Core i7 for user development. The robot supports OTA updates, secondary development, and an additional computing dock station, making it suitable for teams testing their own autonomous navigation, mapping, and motion control algorithms.

Design and Movement on Complex Surfaces

Unitree A2 Pro is designed for fieldwork, carrying equipment, and moving along routes where a quadruped walking scheme is required. The dimensions of the robot dog in a standing position are 820 × 440 × 570 mm, and in a folded position 720 × 550 × 220 mm. The weight is about 35 kg without the battery and about 42 kg with the battery, the actual weight should be checked for a specific delivery.

The mechanical part consists of 12 degrees of freedom and PMSM joint motors with an internal rotor. The maximum torque is about 180 Nm, the range of joint motion covers the body −58°…58°, thigh −134°…180° / −89°…225°, and shin −158°…−30°. The robot dog moves at a speed of 0–3.7 m/s, in certain modes can approach 5 m/s, overcomes steps up to 30 cm, slopes of about 45°, and climbs to a height of approximately 0.5–1 m depending on the scenario.

Navigation and Autonomous Operation

Unitree A2 Pro is equipped with two LiDARs located at the front and rear, an HD camera, and front light. This configuration is needed for obstacle detection, spatial orientation, data collection for maps, and movement in areas with complex geometry: between equipment, racks, technical passages, stairs, ramps, and open areas with uneven surfaces.

Autonomous navigation depends on settings, software stack, map quality, route type, and additional modules. The A2 Pro can be used as an inspection robot, a platform for mapping, or a stand for testing autonomous movement algorithms. For more complex scenarios, GPS, 4G, and wireless vector following extensions are available, but their availability should be clarified before ordering.

Power and Duration of Operation

The power supply of Unitree A2 Pro is based on two battery slots and two batteries. One battery has a capacity of 9000 mAh, or 453.6 Wh, two batteries — 18,000 mAh, or 907.2 Wh. The system supports hot-swapping of batteries, so the robot can return to the route faster after one of the batteries is discharged.

Without a payload, the robot operates for over 5 hours and covers approximately 20 km. With a 25 kg load, it is claimed to operate for over 3 hours and approximately 12.5 km of the route. In practice, these values depend on the weight of installed modules, speed, frequency of stops, temperature, type of surface, slope, stairs, and control mode.

Applications of Unitree A2 Pro

• Inspection of Industrial Facilities. The robot dog moves through workshops, closed warehouses, and outdoor sites, carrying cameras and measuring instruments for equipment monitoring.
• Automated Logistics. The device delivers loads weighing up to 25 kg along routes where there is uneven flooring, thresholds, stairs, or transitions between rooms and outdoors.

Tips Before Purchase

• Clearly Define the Target Task. Write down the main usage scenario of the device: regular inspection rounds, carrying loads in logistics, 3D mapping of the area, warehouse patrolling, laboratory research, or technology demonstration.
• Consider the Specifics of Useful Load. Calculate the working weight of the equipment, focusing on a dynamic limit of up to 25 kg while walking. The static load indicator of 100 kg is a maximum support parameter and is not calculated for movement.
• Maximize the Use of the Dual LiDAR System. Use the standard configuration with two sensors to build high-precision 3D maps, autonomous navigation on complex industrial routes, and confident obstacle avoidance.
• Analyze Operating Conditions. Evaluate the working area in advance: the presence of stairs with a step height of up to 30 cm, slope angles (up to 45°), type of flooring, temperature range from -20 °C to +55 °C, as well as dust and moisture levels for using IP56–IP67 protection.
• Plan the Timing of Autonomous Missions. Note that a walking duration of over 5 hours is possible without a load, and under a load limit of 25 kg, it is over 3 hours. For continuous operation, schedule battery replacement and recharging in advance.
• Design Integration of Third-Party Equipment. Check the compatibility of your sensors, cameras, or manipulators with onboard interfaces RS485, CAN, Gigabit Ethernet, and USB 3.0 Type-C, as well as compatibility with power lines 12 V, 24 V, or direct BAT output.
• Clarify the Exact Configuration of the Delivery. Since the basic set may change, be sure to agree on the availability of GPS and 4G modules, additional batteries, fast charging, and AI expansion boards before ordering.
• Ensure Service Support. Agree in advance with the supplier on the terms of the 12-month engineering warranty, delivery times for components, availability of technical consultations, and basic training for your team in Ukraine.
