The Unitree A2-W Wheeled Quadruped Robot is an industrial-grade, high-performance mobile robotics platform engineered for demanding applications that require strength, speed, and intelligent autonomy. By combining quadruped agility with wheeled efficiency, the A2-W delivers exceptional mobility across complex and mixed terrain.
Powered by an 8-core high-performance CPU for platform functions alongside an Intel® Core™ i7 for user development, the A2-W offers robust computing power for advanced AI, perception, and custom algorithm development. Its approx. 180 N·m peak joint torque enables powerful movement, allowing the robot to climb steps up to 30 cm and handle slopes of up to 45° with confidence.
Built from aluminum alloy and high-strength engineering plastics, the A2-W balances durability with a lightweight, agile structure. It supports 25 kg of continuous walking load and up to 100 kg standing load, making it suitable for inspection, logistics, research, and industrial automation tasks. With a maximum running speed of up to 5 m/s, the robot delivers fast, efficient traversal without compromising stability.
Advanced mobility is enhanced by a dual-sided perception system, providing reliable environmental awareness for navigation and obstacle avoidance. The dual-battery system (9000 mAh / 18,000 mAh options) ensures extended operating time and flexibility for long missions.
Designed to be lighter, faster, and tougher, the Unitree A2-W Wheeled Quadruped Robot is a powerful solution for industrial operations, research institutions, and advanced robotics development, delivering endurance, intelligence, and exceptional terrain adaptability in one versatile platform.
