Recently, the Beijing Humanoid Robot Innovation Center released its self-developed general humanoid robot "Tiangong" in Yizhuang, Beijing. It realizes the world's first humanoid running of a full-scale humanoid robot with pure electric drive, and can also be flexibly expanded and iterated as a parent platform to meet the application needs of different scenarios.

Walking on flat ground, up and down stairs, brisk running at 6 km/h...... With a height of 163cm and a weight of 43kg, Tiangong has achieved a breakthrough in the industry and has become the world's first full-size humanoid robot capable of humanoid running. Guo Yijie, head of motion control at the Beijing Humanoid Robot Innovation Center, said it wasn't easy. "Running requires high force distance and rotation speed of the joints, and it is also difficult to control the robot's rising attitude when taking off, and how to land softly on the ground when the legs are landing. ”
Guo Yijie said that if traditional model-based methods or manual strategy design are used, it will require a lot of work, and the resulting gait may be stiff and less anthropomorphic. However, through a learning method, the robot can master the balance in the air and the suppleness of the landing through a lot of training, and learn the anthropomorphic posture.

The learning method Guo Yijie mentioned is a new humanoid robot motor skills learning method independently developed by the Innovation Center - "predictive enhanced imitation learning based on state memory".
"After the robot completes an action, it will be scored by the equivalent of a coach, and it will improve based on the score. Guo Yijie said that the process is carried out in the simulation engine of the simulation, and thousands of robots are trained in a scene of tens of thousands of square meters. 10 hours of training in this scenario is equivalent to 100 days of round-the-clock training for 1 robot in the physical world, which can make the robot learn efficiently and achieve a more robust, anthropomorphic, and generalized effect.

The "Tiangong" robot is equipped with multiple visual perception sensors, with a computing power of 550 trillion operations per second, and is equipped with a high-precision inertial measurement unit (IMU) and 3D vision sensors. In the case of blind vision, "Tiangong" can smoothly pass through slopes and stairs, and can also adjust the gait agile for stumbling and stepping on the air.
Guo Yijie said that the existing motor skill learning methods will be applied to the follow-up robot whole body action control and operation skills learning, so that the robot can both move and operate, and provide stronger movement capabilities for future scene services.

As a general parent platform, "Tiangong" has open source openness and compatibility and scalability, which can realize open call communication interfaces, flexibly expand software and hardware and other functional modules, and fully meet the needs of different application scenarios.
Liu Yizhang, head of the ontology platform group of the Beijing Humanoid Robot Innovation Center, said that on the basis of this parent platform, the hardware can expand the dexterous arms with 7 degrees of freedom, and the five-fingered dexterous hands that can do grasping operations. In addition, Tiangong can expand the computing power of 500TOPS to meet the application of large model algorithm development.

"Based on our compatibility, scalability and openness, other robot companies, including scientific research institutions, can configure specific robots according to different needs on the basis of the parent platform, and do specific application development in scenarios similar to factory manufacturing, home services, and security inspections. Liu Yizhang said that "Tiangong" is a general, basic, stable and reliable version of the robot, which can help more enterprises reduce repeated investment and research and development.
According to the relevant person in charge of the Beijing Economic and Technological Development Zone, Yizhuang currently brings together 110 robot ecological enterprises to form a whole industrial chain system of robots covering core components, complete machines and applications. In the next step, Beijing Yizhuang plans to formulate a three-year action plan for the humanoid robot industry, and prepare for the construction of a robot testing and evaluation center, a parts finishing center, a robot innovation exhibition center, etc., to form a good industrial ecology and create a new engine for development.
