Since spatialship space of United States and the Mir orbital complex of Soviet Union / Russiathe astronauts and cosmonauts they needed robots and cranes to connect the modules, conduct experiments, capture satellites or free them space.

What’s new on the ISS is a whole display of engineeringthe arm robotics European Union, ERA, fruit of the collaboration between Europe Yes Russiawill move loads from inside to outside the station and vice versa, avoiding many walks spaceit will also support the cosmonauts Yes astronauts when they go out space.

Though there is robotic arms: Canadarm 2 Yes KiboRMSnone reach the Russian segment, while this new one will be anchored to the module nauka in Russian (Science).

ERA operates automatically or semi-automatically, it is controlled from inside or outside the station or from the Ground, in real time or programmed. It is 11.3 meters long. It lifts loads up to 8 tons, with a movement precision of up to 5 mm. It has 7 degrees of freedom (7 joints), each end of which has 3 degrees of freedom. Also it can “walk” like some caterpillars i.e. one end of the arm is attached to the station and the other is looking for an attachment point, once that is done the first end can be released and maneuver.

ERA joins its worthy predecessors, participants in the space exploration.

CANADARM

In the 70s, the JAR built for spatialship spaceship, with the idea of ​​repairing satellites or providing them with maintenance in Earth orbit. Something that ultimately didn’t happen. For it, Canada contributed his Canadarm robotic armTo catch satellites.

Canadarm measures 15.2 meters long, 38 cm wide, with 6 degrees of freedom. It handled loads of up to 266 tons. The arm robotics he succeeded in all his maneuvers, he dropped several satellites from the shuttle, including the famous space telescope Hubble, and on later missions captured it for maintenance. In addition, he carried a platform with the astronauts to maintain the telescope or build the international space station.

With a 15 meter extension (OBSS), Canadarm checked the integrity of the shuttle in space before returning, this after the disintegration of the Colombia in 2003.

Today the Canadarm They are in museums. For the Space station he built himself Canadarm of them. 17.6 meters long and 35 cm wide. Work with loads up to 116 tons. Unlike the first version, this one can “walk” outside the station. Also, capture the freighters mountain bike, Dragon Yes Swan, and brings them to the docking bay. It is controlled from the station or from the Ground.

DEXTER

Yes Canadarm 2 is the arm DEXTER it’s the hand Also Canadian, it is a 3.5 meter torso, with two arms also 3.5 meters long, which have attachment systems, video and data connections, d a television camera and a light. DEXTER works by attaching to the outside of the station or connects to Canadarm 2 and operates at a greater distance. In addition, both are mounted on the MBS mobile platform, and move on the 108 meters of rails that exist outside the station.

Once again, Canada is heading for the new frontier, the Moon. Canadarm 3 will support future work Gateway lunar orbit stationin the following decade.

Canadarm 2 Yes DEXTERthe spatial pride of Canadaare honored on the $5 bill Canadians.

STRELA

Since Mir orbital complex wing Station international space, Russia use your space cranes Strela (Arrow), which are used to move cosmonauts and modules from place to place. Strela It is a telescopic crane up to 14 meters long. In the Mir orbital complex, Strela reached all the modules, while in the Space station The international only reaches the segment Russian.

In the international space station operate two cranes Strelaone coupled to the module poison and the other to Zarya.

KIBORMS

Finally, the module japanese kibohas an experimentation platform located outside the module, to work with it, it has robotic arm RMS.

KiboRMS (YWAM RMS) are two connected arms. One 10 meters long, which lifts loads of up to 7 tons. Another arm of 2 meters is connected to it, for precision activities, which lifts loads up to 300 kg. Both arms have connections, light, television camera, with 6 degrees of freedom each and can use the same connections of Canadarm 2. german@astropuebla.org
