Generally speaking, robots fall into two major categories-- "humanoids" and "non-humanoids." Non-humanoids appeared earlier and have a wide range of applications like the robotic arms that are now standard equipment on US space shuttles and space stations.
一般來說，機器人有「人形」與「非人形」兩大類，非人形機器人出現較早、應用也廣。譬如機器手臂早就脫離了地心引力，成為美國太空梭、太空站不可或缺的配備。
