Beskrivelse
Moving mechanical structures are used increasingly in almost all vital sectors of humanity. The robots are able to process integrated circuits sizes micro and nano, on which the man they can be seen even with electron microscopy. Dyeing parts in toxic environments, working in chemical and radioactive environments, or at depths and pressures at the bottom of huge oceans, or even cosmic space conquest and visiting exo-planets, are now possible, and were turned into from the dream in reality, because mechanical platforms sequential gearbox. Robots were developed and diversified, different aspects, but to-day, they start to be directed on two major categories: systems serial and parallel systems. Parallel systems are more solid, but more difficult to designed and handled, which serial systems were those which have developed the most. In medical operations or radioactive environments are preferred mobile systems parallel to their high accuracy positioning.
