In quadrupedal robotics, Chinese company Unitree is making notable strides with its latest creation, the B2. Building on the success of its predecessor, the B1, the B2 showcases significant improvements, positioning itself as a formidable player in the industrial robotics landscape.
Designed for diverse applications such as industrial automation, inspection, emergency rescue, security patrolling, and robotics education, the Unitree B2 stands out with its impressive technical features. Equipped with two HD optical cameras, two depth-sensing cameras, and a LiDAR module, the robot autonomously navigates challenging terrains, demonstrating its adaptability in real-world scenarios.
Unitree’s commitment to advancement is evident in the B2’s performance metrics. With a remarkable running speed of 6 meters per second, it claims the title of “the fastest known industrial-grade quadruped robot on the market.” The ability to jump a horizontal distance of 1.6 meters and step over obstacles up to 40 cm in height underscores its agility and versatility.
One of the critical improvements lies in the B2’s enhanced load-bearing capacity. While the B1 could carry a load of up to 20 kg while walking, the B2 doubles this capacity, managing an impressive 40 kg. Even standing still, it can support up to 120 kilograms, showcasing its robust construction and stability for industrial operations.
The B2’s endurance is equally noteworthy. A swappable 45-Ah/2,250-Wh lithium battery can be unloaded for five hours on a single charge. Even when carrying a 20 kg load, it reportedly maintains over four hours of continuous walking. This substantial improvement in battery life enhances the robot’s efficiency and suitability for prolonged tasks.
A critical enhancement in the B2 lies in its leg joint actuators, delivering 170% more torque than its predecessor. With 360 Nm/266 lb-ft of torque, the robot gains increased flexibility and stability, crucial for executing precise industrial maneuvers.
In a video demonstration, the Unitree B2 showcases its capabilities by climbing stairs, resisting external forces, and performing various quadrupedal feats. These practical demonstrations underscore the robot’s potential in real-world applications, solidifying its status as a cutting-edge industrial-grade quadruped robot.
