Limbs were important appendages of organic bodies and many types of mechanical chassis. They were typically designed for motion and/or manipulation, and were found on most sentient and non-sentient species throughout the galaxy, and many droids and other artificial constructs.
Humans and many other important sentient species were bipedal, with two legs and two arms, and this form was imitated by many droids; but there were many variations. Sometimes these were relatively subtle, especially in the construction of hands, feet and their digits.
Many Birds and Reptavians such as Dactillions and Ibbots possessed the ability of flight via the usage of specialized limbs in the form of wings often taking the form of either a feathered, membraned, or insectoid structure.
Other species and designs, however, had limbs of more radically different designs, like the dianoga with its tentacles and prehensile eyestalk, or the R-series astromech, which could travel in a bipedal or tripodal configuration, and had a wide variety of manipulator arms that could be extended from their torso and head.
