In order to provide more efficient working capabilities in diverse scenarios such as power inspection, emergency rescue, industrial testing, education and scientific research in the industrial field, the upgraded Unitree B2 has been fully optimized. Among them, in order to reduce the charging time after each mission, Unitree B2 expanded the battery capacity to 45000mAh, increased the rated energy to 2250Wh, and increased the battery life by 200%.

According to Yushu Laboratory test data, Unitree B2 has a maximum battery life of more than 5 hours without load. When the load reaches 20kg, Unitree B2 can still maintain a working time of more than 4 hours under continuous motion. . The substantial improvement in battery life effectively solves the battery life anxiety problem of industry-level applications.

Currently on the Chinese market, industry-level quadruped robots on sale generally have a nominal battery life of only 2-4 hours. Therefore, in order to ensure the normal execution of inspection tasks, purchasing customers have to increase procurement costs or reduce inspection costs. Check frequency. However, Unitree B2, as the first industry-level quadruped robot product to increase its battery life to 5 hours, further improves the inspection efficiency of quadruped robots.

▍Peak torque 360N.m, overall efficiency increased by 170%, capable of climbing 40 cm steps proficiently

With the surge in urban power consumption and the reduction of urban land occupation, many transmission network substations adopt multi-layer steel structure designs to integrate control rooms, towers and transmission lines with the ground. However, this design also increases the difficulty of robot inspections, especially for substations that use multi-layer steel structure hollow stairs, which have always been difficult for quadruped robots to climb.

Starting from the pain points of power inspection, Yushu developed its own joint motor, and at the same time increased the peak torque of Unitree B2 to 360N.m, improving the overall performance by 170%.

Joint ability is a key factor in preventing falls when going up and down stairs. According to test data released by Yushu Laboratory, Unitree B2 can easily go up and down 40 cm steps. Compared with the previous generation product, Unitree B2's ability to go up and down stairs has doubled. Thanks to the high peak torque of the joint motor, Unitree B2 can complete more complex and challenging tasks.

▍The running speed of 6 meters/second is 3.6 times ahead of Boston Dynamics, making it the world’s fastest quadruped robot in the industry

According to previously announced data, Boston Dynamics Spot moves at a speed of approximately 5 kilometers per hour, which can be converted to 1.38 meters per second according to the formula. This is also the fastest traveling speed of the Spot quadruped robot. However, what is the fastest movement speed of Unitree B2? The answer is 6 meters/second, which is far ahead of Spot by 4.3 times. Therefore, Unitree B2 has become one of the fastest industrial quadruped robots on the market.

In addition to fast running speed, Unitree B2 also has excellent jumping distance. According to Yushu laboratory test data, its jumping distance on stable ground can reach 1.6 meters. Excellent jumping ability makes Unitree B2 widely used in complex scenarios such as fire rescue and geological disaster rescue.

▍120kg standing load capacity, performance increased by 1.5 times, capable of meeting demanding industrial special tasks

Different from inspection tasks, industrial-grade quadruped robots need to have greater load capacity to handle tasks such as handling and assembly. Unitree B2 increases the standing load capacity to 120kg, and the comprehensive load capacity is increased by 1.5 times. In addition to the standing load, the mobile working load capacity of the quadruped robot is equally important. Official data shows that Unitree B2’s load is greater than 40kg in continuous walking state. This means that Unitree B2 can carry heavy objects no matter how heavy it is. Whether it is carrying out distribution tasks or performing patrols on assembly modules, it can be easily handled.

▍Perception capabilities have been upgraded to fully cope with complex operations in all scenarios

Facing the differentiated needs in industrial scenarios, Unitree B2 adopts a modular assembly solution that can support the installation of multiple sensors and optical cameras. In response to the needs of the construction and surveying and mapping industries, you can choose to install 3D lidar to achieve three-dimensional scanning of the working space, build a three-dimensional measurement map, and simultaneously perform tasks such as path planning and autonomous obstacle avoidance. In addition, combined with the use of depth cameras, optical cameras and other modules, faster and more accurate positioning capabilities can be obtained.

▍IP67 level protection, no fear of severe cold or heat, fully coping with extreme operating environments

In industrial scenarios, extreme environments such as high temperature and humidity, low temperatures and cold temperatures, and toxic and harmful gases are often encountered. The use of quadruped robots greatly reduces the risk of injury that may be suffered during manual work. However, to meet the ability to operate in extreme environments, sufficient protection capabilities are essential. If you have seen the Unitree B1 promotional video before, you must be impressed by its underwater operation scene.

Unitree B2 continues the full-scene operation capabilities of B1 and has IP67 dustproof and waterproof capabilities, which means that it can completely protect against the intrusion of external dust and water, ensuring stability in harsh weather conditions such as rain, snow, and fog. run.
