Stellar Explorer
Lighter, Faster, Tougher — Industrial-Grade Legged Robot
With a maximum joint torque of approximately 180 N·m, the A2 sets a new standard for legged robots. Weighing around 42 kg with battery, it can support a standing load of up to 100 kg and carry 25 kg continuously while walking — making it a true industrial workhorse.
Equipped with a dual-battery system (18,000 mAh / 907.2 Wh total), the A2 delivers over 5 hours of unloaded runtime and 3+ hours carrying 25 kg. Walking range exceeds 20 km unloaded. Hot-swappable batteries ensure seamless operation with zero downtime — swap one battery while the other keeps the robot running.
The A2 features dual industrial LiDARs (front and rear) combined with an HD camera and front light for comprehensive environmental perception. This multi-sensor fusion enables precise obstacle detection and autonomous navigation across complex and dynamic environments.
The A2 handles up to 45-degree slopes, 30 cm steps, and can climb obstacles between 0.5 to 1 meter high. With speeds up to 5 m/s and advanced locomotion algorithms, it navigates extreme environments that would stop conventional robots — from rocky trails to industrial scaffolding.
With IP56 protection (up to IP67 for core components on the A2-PRO), the A2 operates reliably from -20°C to 55°C. A triple power system ensures consistent performance across extreme temperature ranges. From heavy rain to dusty industrial sites, the A2 keeps working when others can't.
Versatile deployment across logistics, industrial inspection, and emergency rescue operations.
Choose the A2 variant that fits your needs — from industrial standard to maximum protection and expandability.
