Unitree Robotics introduces the A2 Stellar Explorer, a formidable quadruped robot designed for industrial-grade missions. Demonstrating unmatched agility and endurance, the A2 represents a leap forward in four-legged robotic capabilities. It’s lighter, stronger, faster—and purpose-built for demanding environments.
Technical Highlights & Performance
- Weight & Endurance: The A2 weighs approximately 37 kg with its batteries. It achieves up to 5 hours (or 20 km) of continuous operation when unloaded, and 3 hours (around 12.5 km) under load.
- Load Capacity: Supports a 100 kg payload while stationary; during motion, it handles up to 25 kg, with tests showing a 30 kg load maintained across 12 km on a charge.
- Mobility & Terrain Handling: Achieves top speeds of 5 m/s (11.2 mph), climbs 30 cm steps, and navigates 45° slopes with ease. It even smashes through glass and swiftly recovers from falls.
- Sensing & Resilience: Equipped with dual LiDAR (front and rear), HD camera, and front illumination—ensuring 360° environmental awareness. Built with 12 robust motors, it continues operating effectively after stumbles or impacts.
- Power System: Features a hot-swappable dual-battery system (9000 mAh each) and a triple-redundancy power setup, enabling uninterrupted operations in temperatures from –20 °C to 55 °C.
- Durability & Connectivity: Crafted from aluminum alloy and high-strength polymers, the A2 boasts IP56 rating (IP67 on critical components), wired and wireless connectivity (Wi-Fi 6, Bluetooth 5.2), optional GPS/4G modules, plus external I/O including USB-C, Gigabit Ethernet, and CAN interfaces.
Industrial Applications & Strategic Impact
Built for real-world challenges, the A2 excels in:
- Industrial Inspection in off-road or dangerous environments
- Emergency Response and search-and-rescue missions
- Logistics & Payload Delivery across varied terrain
Its rugged build and open development platform invite customization, enabling researchers and enterprises to deploy and upgrade it in the field.
