The Unitree A2 PRO Robotic Dogis an advanced quadruped robot designed for demanding industrial and field applications. Building on the proven A2 platform, it combines rugged engineering with enhanced perception and computing capabilities, making it one of the most capable and versatile robotic solutions available. With a compact yet durable frame built from aluminum alloy and high-strength engineering plastics, the A2 Pro is engineered to thrive in both indoor and harsh outdoor environments, making it ideal for logistics, inspection, research, and custom industry deployments.

Equipped with 12 high-performance joint motors powered by low-inertia PMSMs, the A2 Pro delivers up to 180 Nm of torque for responsive, powerful movement. Its wide range of motion allows for agile walking, climbing, and recovery across varied terrain. Dual encoders and industrial-grade bearings ensure precision and long-term reliability under heavy workloads, maintaining consistent performance in mission-critical tasks.

The A2 Pro supports up to 100 kg of standing load and 25 kg of continuous walking load, offering strength and endurance for real-world operations. Its dual hot-swappable batteries enable up to 5 hours of runtime unloaded or 3 hours with load, covering distances up to 20 km. With an upgraded sensor suite that includes dual LiDAR units and an HD camera, plus optional modules such as GPS, 4G, and wireless vector following, the A2 Pro delivers enhanced navigation, mapping, and autonomous operation capabilities.

Connectivity and compute power further set the A2 Pro apart. In addition to Wi-Fi 6, Bluetooth 5.2, USB 3.0, Ethernet, and CAN/RS485 interfaces, it supports an optional high-computing expansion dock for AI-intensive applications. Combined with continuous OTA upgrades and open secondary development, the A2 Pro is a flexible, future-ready platform tailored for industries seeking advanced robotics solutions with expanded intelligence and durability. Its IP56IP67 ingress protection further reinforces its readiness for challenging environments, making it a trusted choice for organizations with high-performance robotic demands.
