Recently, the robotic arm of the Chinese space station, which is far in space, is also like a little tiger, sticking out a small head from one side of the space station assembly, and then firmly "grabbing" the docking port.

  In the distant space, the robotic arm and the ground researchers are always guarding the astronauts in orbit!
