Shulou(Shulou.com)12/24 Report--

Recently, Yushu released the new Unitree B2 four-legged robot dog, which focuses on meeting the application needs of the industry. This is the third important product released by Yushu in the second half of this year. The other two models are the consumer quadruped robot dog Go2 and the general humanoid robot H1. The rapid development speed of Yushu further proves its leading position in the field of four-legged robot dogs in the world.

Unitree B2 has significantly improved in many aspects, including comprehensive range, joint performance and motor ability, high load carrying capacity and perceptual ability. These improvements enable B2 to be successfully applied to a variety of industrial scenarios. Especially in the field of electric power inspection, B2 shows great advantages.

The ability to operate for 5 hours will be increased by 200%.

In order to provide excellent performance in many scenarios, such as electric power inspection, emergency rescue, industrial inspection, education and scientific research, B2 has carried out omni-directional optimization and upgrading. The battery capacity has been expanded to 45000mAh, the rated energy has reached 2250Wh, and the battery life has been greatly increased by 200%.

According to the official data of Yushu, B2 can work continuously for more than 5 hours under no load, even if it carries 20kg load for continuous exercise, the working time is more than 4 hours. This greatly solves the problem of service life of industry-level applications and improves the efficiency and reliability of patrol tasks.

Joint performance surge 170% Peak torque 360N.m

In order to solve the problems in power inspection, Yushu focused on the key problems, independently developed a new joint motor, and raised the peak torque of B2 to 360N.m, and the joint performance was improved by 170%.

In the multi-story steel structure, especially the climbing process of the hollowed-out staircase, it has always been a difficult point for the quadruped robot dog. B2 can easily climb steps 40 centimeters high, doubling its climbing ability compared with the previous generation. With the joint motor with high peak torque, B2 can accomplish more complex and challenging tasks. This technical breakthrough will greatly improve the efficiency and reliability of electric power inspection.

6m / s running speed four-legged robot dog in the world's fastest industry

According to previously released data, Unitree B2 is a very fast four-legged robot dog. Its fastest moving speed can reach 6 meters per second, which makes it one of the fastest industrial four-legged robot dogs on the market. In addition to running fast, B2 also has excellent jumping ability, which can jump up to 1.6 meters. This makes B2 widely used in complex scenes such as fire rescue and geological disaster rescue. In addition, it also has a B2MurW wheeled foot robot dog that can be replaced and deformed, so as to break the range limit and convert freely.

The standing load capacity of 120kg can meet the demanding special tasks of industry.

Unlike patrol tasks, industrial quadruped robot dogs need to have greater load capacity to handle handling, assembly and other tasks. B2 has made a significant improvement in this aspect, and its standing load capacity has been increased to 120kg, and the comprehensive load capacity has been increased by 1.5 times.

In addition to the standing load capacity, B2 can carry more than the 40kg load in a continuous walking state. This means that B2 can easily do it, whether it is carrying heavy objects, carrying out distribution tasks or patrolling on duty with assembly modules.

The perception ability is upgraded and the ability to deal with complex operations in the whole scene is improved.

In order to meet the needs of differentiation in industrial scenes, B2 adopts a modular assembly scheme, which can support the installation of a variety of sensors and optical cameras. In order to meet the needs of the construction and surveying and mapping industry, we can choose to install 3D lidar to realize the three-dimensional scanning of the working space, construct a three-dimensional survey map, and carry out tasks such as path planning and autonomous obstacle avoidance.

In addition, combined with the use of depth camera, optical camera and other modules, more rapid and accurate positioning ability can be obtained.

IP67 class protection against severe cold and heat to deal with extreme working environment in an all-round way

B2 has ultra-high protection capability and is suitable for extreme environments in industrial scenes. It continues the full scene operation ability of B1, and has IP67-level dustproof and waterproof ability, and can operate stably under harsh conditions such as high temperature and humidity, low temperature and cold, toxic and harmful gases. This protection capability enables B2 to play an important role in common scenes such as survey and exploration, fire rescue, earthquake relief, epidemic prevention and eliminate virus.

Yushu has fully realized the intelligent operation and maintenance cooperation of dozens of customers for robot dog power inspection.

After seven years of rapid growth, Yushu four-legged robot dog has completed a comprehensive landing application to solve the problem of untimely data synchronization of manual inspection, a remote intelligent inspection system has been customized, which combines robot dog inspection / operation with manual check. the workload is reduced by 80%. In addition, Yushu provides customized solutions, using four-legged robot dogs carrying a variety of sensors to patrol in a small space to quickly find problems and report them. In the future, Yushu will continue to explore more industrial applications in the field of inspection.

Conclusion and the Future

Yushu first realized the commercial application of four-legged robot dog as early as 2017, and created a low-cost and high-performance four-legged robot dog technology solution. As a new product of industrial quadruped robot dog, Unitree B2 once again exceeds people's expectation of its application ability. With electric power inspection as the core, Yushu has expanded its application in the fields of fire rescue, eliminate virus, geological exploration, industrial inspection and so on. With the digital transformation of the inspection track, B2 will play an important role in promoting the transformation of industrial modernization, bringing the possibility of more changes to the industry. Yushu is a leader in the four-legged robot dog industry and an innovator in intelligent inspection, bringing unlimited possibilities to the field of industrial intelligence.
