In the field of space technology testing on China's space station, a groundbreaking test has come to an end: a pipeline inspection robot has successfully completed an on-orbit test. This test not only verifies the adaptability of the robot in the complex pipeline environment and the safety of its variable stiffness movement, but also lays a solid technical foundation for the implementation of the future space station pipeline inspection task.
During the test, the astronauts carefully built a simulated piping system, including straight, elbowed and conical pipes of various diameters. In this simulated environment, they conducted a test of the robot's ability to move, a pull-out test in the shrinking state, and a pull-out test after fine-tuning. Thanks to its excellent performance, the robot successfully verifies autonomous motion technology by smoothly traversing pipes of various sizes. In particular, the robot can easily remove complex pipes even in the event of a power failure, which fully proves the safety of its passive compliance mechanism.
The ground team played a key role throughout the trial. Through ground support software, they monitor and record key data such as the robot's position, current, and contact force in real time to ensure that astronauts can successfully complete on-orbit operations. At the same time, the ground team also conducted an in-depth analysis of these data, which provided a valuable reference for subsequent experiments.
The in-orbit test of the pipeline inspection robot marks the first successful test of a special operation robot in the cabin of China's space station. The test not only verifies the design of the pipeline robot with a large diameter change ratio and the key technologies such as multi-level coordinated whole-body motion control, but also proves the autonomous adaptability and motion safety of the robot in the complex space station pipeline environment. This undoubtedly accumulates rich experience for the practical application of future robots in space station pipelines.
Faced with the complexity of the space station's pipeline structure, pipeline inspection robots face great challenges. The large spans, abrupt changes and discontinuities of the pipe diameters require robots to have a high degree of autonomous movement. At the same time, in order to ensure the safety of the robot's movement in the pipeline, it is necessary to adapt to the change of pipe diameter and avoid getting stuck in the pipeline in unexpected situations. In order to solve these problems, the pipeline inspection robot adopts a bionic variable stiffness design.
The robot also has a modular structure, has 23 degrees of freedom, and is equipped with several types of sensors. Its "smart brain" is able to use sensor information throughout the body to calculate posture and position, and develop the best exercise strategy. On the premise of ensuring the safety of the pipeline, the robot can flexibly adjust the position, speed and force output of each joint in the body to achieve smooth movement in the space station pipeline.
The success of this test not only demonstrates the advanced level of China's aerospace technology, but also provides strong support for the maintenance and management of the future space station. With the continuous advancement of technology, it is believed that pipeline inspection robots will play an important role in more fields and contribute to the cause of human space exploration.
