From Home to Industry, How Bionic Quadrupedal Robots Are Reshaping the World with Technology

Bionic quadruped robot, can imitate animal walking, running, jumping and other actions, in a number of areas to show the value of the application. These seemingly simple robots, the reason why in many aspects than the real animal “better”, is that it contains a complex scientific and technological essence. As Unitree Robotics' star robotic dogs - Unitree Go2 and Unitree B2, what are the technological attractions behind them?

Unitree Go2: The Intelligent Family Companion

As Unitree Robotics' masterpiece in the consumer market, Unitree Go2 has excellent sensing ability, intelligent interaction and flexible movement performance, and is capable of dancing, flipping, inverting and other difficult “animal performances”, with high playability, bringing a new intelligent experience for modern families. It is highly playable and brings a new intelligent experience to modern families.

This bionic quadruped robot is equipped with Unitree Robotics' self-developed 4D LIDAR L1, which realizes 360°x90° omni-directional environment sensing, allowing Go2 to navigate through any terrain with ease. In terms of motion performance, based on the excellent performance of Unitree Robotics' self-developed motors, Go2's joints are able to provide a peak torque of up to 45N-m, supporting it to complete a variety of complex movements. In order to avoid overheating of the motor caused by long-time transportation, Go2 also has a heat pipe assisted cooling system in the knee joint area to ensure the stable operation of the machine.

Go2 adopts OpenAI's GPT series of models in large languages, which gives it powerful data processing and analysis capabilities. When interacting with humans, Go2 not only understands commands accurately and responds quickly, but also displays certain emotional colors during Q&A interactions, rather than AI-style “program language”. In addition, Go2 also opens up model interfaces, supporting users to mount different AI models according to actual needs, further expanding its application scenarios and potential.

In practical applications, Unitree Go2 is able to simulate the ball-chasing and ball-fetching games of real pet dogs, as well as autonomously set up patrol routes for security monitoring, making it an ideal choice for scenarios such as family entertainment, pet companionship, and house-sitting.

Unitree B2: The right hand in industry

If Unitree Go2 is the ideal companion for smart life, Unitree B2 is an all-round warrior in the industrial field. This industrial-grade bionic quadruped robot has excellent endurance, joint performance and locomotion, high load-bearing capacity, and sensing ability, and is suitable for electric power inspection, firefighting and rescue, and geologic disaster rescue.

Unitree B2 is one of the fastest industrial-grade quadruped robots, with a speed of up to 6m/s. It also has excellent jumping ability, and is able to cross 1.6m obstacles with ease. Based on new joint motors developed by Unitree Robotics, B2 has a peak torque of 360N.m, a 170% increase in joint performance, and is able to climb 40cm high steps with ease.

In addition to the improvement of sports performance, B2 has also been comprehensively upgraded in terms of endurance and load carrying capacity. Its battery capacity has been expanded to 45,000mAh, with a rated energy of 2,250Wh. It can continue to work for more than 5 hours under no-load condition, and maintain stable operation for a long period of time even when carrying a load of 20kg. This improvement greatly solves the endurance problem in industry-level applications, and improves the efficiency and reliability of inspection tasks.

In addition, B2 also has IP67 dustproof and waterproof capabilities, and can operate stably in harsh environments such as high temperature and humidity, low temperature and cold, toxic and harmful gases. This means that B2 can "self-defense" in high-risk scenarios such as power inspections and fire rescue.

In conclusion: Technology empowers life. The bionic quadruped robots, Unitree Go2 and Unitree B2, have shown great application potential in their respective fields. In the future, Unitree Robotics will continue to evolve the Unitree series of robotic dogs with the power of science and technology, in order to cross more application boundaries and empower a better, more convenient and safer life.
