Unitree A2-W Standard Quadruped Robot Dog with Wheels

Description

A2-W Standard: Wheel-Leg Hybrid Quadruped for Extended Range and Dynamic Mobility
The A2-W Standard is a wheel-leg hybrid version of Unitree’s A2 quadruped platform, designed for superior endurance, speed, and terrain versatility. Combining the agility of legged motion with the efficiency of wheel-assisted travel, the A2-W Standard delivers extended range and high payload performance for industrial, research, and field robotics applications.
Powered by an 8-core high-performance CPU and optional Intel Core i7 computing module, it supports both high- and low-level development while maintaining full compatibility with Unitree’s intelligent control and sensing ecosystem. The dual-battery system provides hours of continuous operation, while advanced LiDAR and camera sensors ensure precise perception and navigation.
Key Features of the A2-W Standard
Wheel-Leg Hybrid Mobility:Integrates powered wheels on each limb, allowing seamless transitions between legged locomotion and wheeled travel for greater speed and energy efficiency.
Extended Endurance:Operates up to 4–5 hours unloaded (≈ 20 km range) or 2.5–3 hours with a 25 kg payload, maintaining stability and terrain adaptability.
High Load Capacity:Supports 20–25 kg effective payload while maintaining agile performance and balance during motion and manipulation tasks.
Dual-Battery Power System:Includes 9,000 mAh batteries (dual = 18,000 mAh / 907.2 Wh) with 1-hour charge time, supporting long-duration deployments and hot-swap operation.
Rugged Performance:Operates in temperatures from -20 °C to 55 °C, climbs stairs up to 28 cm, single steps up to 90 cm, and slopes up to 45°.
Advanced Sensing and Vision:Equipped with 1 LiDAR and a wide-angle camera (expandable to 2) for real-time obstacle avoidance, mapping, and situational awareness.
Industrial-Grade Control:Powered by a dual-processor system (8-core CPU + Intel Core i7) with dual encoders and high-speed, low-inertia rotor motors for smooth, precise movement.
Developer-Ready Ecosystem:Supports Isaac SIM and high/low-level secondary development with robust API access and modular external interfaces.
