What is the ability to ask the small robotic arm of the sky?

China Space Station has been launched for more than ten days after the launch of the experimental compartment. After the connection between the Tianshi experimental compartment and the core compartment form a new space station combination, the three astronauts of Shenzhou 14 have recently carried out a series State settings, including: establishing a manned environment; completing the large -scale daily -oriented device in the rail performance test; setting, power generation, and installation of the scientific experimental cabinet equipped by the test cabin.

The small robotic arm installed outside the test compartment also completed a series of rail function and performance tests recently. All indicators of small robotic arm performed well and achieved the expected results. On the 3rd, China Manned Aerospace Public Account released a video, showing the process of small robotic arms testing on the orbit.

The effective operation radius of small robotic arm is 5 meters maximum load 3 tons

From the screen taken by the directional camera outside the cabin, we can see that the small robotic arm first carried out the "cabinet crawling test". Its joint movement was flexible and can achieve a motion ability similar to human arms. Compared with the large robotic arm with a length of 10 meters and a maximum of 25 tons of the core compartment, the small robotic arm of the Tiangan experimental cabin should be more "short and smart". The length is only about 5 meters and the carrying capacity is 3 tons. The design purpose of this "small hand" is to grasp small and medium -sized equipment to perform more refined operations. Don't look at the small head, it can shoulder the installation and replacement of the load of the off -cabin independently.

The size of the robotic arm will provide support for the mission and other tasks of the cabin

Small robotic arms can be used alone, and combined with large robotic arms can be combined with a large robotic arm; supporting astronaut out of the cabin, off -compartment status inspection, out -of -the -cabin cargo transfer and installation, off -class maintenance and maintenance, load care, optical facilities maintenance, etc. Application task.

Small robotic arm: the most accurate space station robotic arm

Earlier, when I asked the experimental cabin before, our reporters had observed small robotic arms nearby.

CCTV reporter Li Ning: The small robotic arm installed on the test cabin is 5 meters in length. It is the most accurate space station robotic arm.

Wang Xin, deputy chief commander of the Five Hospital Space Station System of Aerospace Science and Technology Group: The large robotic arm is a 10 -meter length, and the small robotic arm also has 7 degrees of freedom. There are also many such adapters such as such robotic arm on the cabin. It can be crawled on the cabin, which is basically the same as the function of the arm.

Wang Xin introduced that they can work independently for different characteristics of robotic arms. In addition, it can also be used by combination of arms. The length of the two arms can be reached 15 meters after docking, which can expand the range and distance of the robotic arm.
