Robot Unitree A2 Stellar acrobatically executes back flips and is capable of supporting the weight of an adult human.
The Unitree A2 Stellar Explorer is a remarkable robot dog designed for tackling tough terrain missions and challenging tasks. Created by Unitree Robotics, this agile and robust quadruped robot is well-equipped for industrial, outdoor, and demanding field applications.
Weighing approximately 81 lbs (37 kg), the A2 Stellar Explorer is built from durable materials such as aluminum alloy and high-quality plastic. Its IP56-rated outer shell offers water and dust resistance, while its IP67-rated inner components provide added protection against the elements.
In terms of mobility and agility, the A2 Stellar Explorer can reach a top speed of 11.2 mph (5 m/s) and climb steep 45° inclines with ease. It can also overcome 1-meter-high obstacles and ascend 30 cm steps, demonstrating its impressive agility. Dynamic movements like backflips and balancing on a single leg further showcase its advanced agility.
The A2 Stellar Explorer is not just agile, but also strong. It can support a moving payload of up to 55 lbs (25 kg) and carry a stationary load of up to 220 lbs (100 kg) when stationary, making it capable of handling heavy-duty tasks or carrying humans in some cases.
The robot's endurance is impressive as well. It can operate for about 5 hours unloaded (covering ~20 km) or 3 hours under load (~12 km) before needing a recharge. Dual hot-swappable 9,000 mAh batteries enable near-continuous operation for 24/7 use.
For sensing and navigation, the A2 Stellar Explorer is equipped with a dual LiDAR system (front and rear), a front-facing HD camera, and AI-powered vision for real-time autonomous navigation in complex terrains. This enables precise obstacle detection and environmental awareness, allowing the robot to navigate challenging environments with ease.
The A2 Stellar Explorer runs on an Intel Core i7 processor, ensuring it can handle computing-intensive tasks. Connectivity options include Wi-Fi 6, Bluetooth 5.2, and optional 4G with GPS for reliable remote operation and control.
The A2 Stellar Explorer is designed for outdoor use in temperatures ranging from -20°C to 55°C, making it suitable for a wide range of environments and weather conditions.
With its combination of agility, load capacity, long endurance, advanced sensing, and robust build, the A2 Stellar Explorer stands as a versatile robotic platform for logistics, inspection, search and rescue, security, and industrial applications. It offers a competitive alternative to other robot dogs like Boston Dynamics Spot at a potentially lower cost.
At industrial events showcasing gadgets and technology, the Unitree A2 Stellar Explorer is often featured as a prototypes demonstrating advanced capabilities in robotics. Its ability to navigate challenging terrains and handle heavy-duty tasks makes it a preferred choice for competitions, further enhancing the development of this emerging technology.
