Canadarm2 robot on the ISS "operated" itself

The other day there was a significant event - a complex system-arm Canadarm2 had surgery to replace their own cameras. This operation was performed for the first time, without the participation of the astronauts. Normally, astronauts spacewalk to repair something on the ISS.

Now the same people on the ISS (and PCO) just watched repair. Of course, the manipulator controlled by the operator, until samoremontiruyuschihsya robots that themselves determine what to do and how, far away. But the physical contact of man and machine was not.

So, self repair was to replace two cameras that fail. One camera is located at the base of the manipulator, broke down again in 2012, and it was removed astronauts. A little later, a second camera (it is located in the upper part of the system), which can be called critical, began to give less than perfect "picture". As a result, it was decided to establish a "barahlyaschuyu" camera instead of the first, is absent. A critical chamber is replaced by an entirely new.

Cameras very large sum, each of them has a size CRT-monitor. When this camera is not mounted as Circuits LEGO. To replace the robot had to unscrew the bolt, mount the camera, make sure that the camera is properly established, tighten the bolt.

New camera crane pulled yourself out of the gateway Kibo, people do not go into space, as was said above.

Here's a video of the whole process, pressed down to one and a half minutes:
