    • The apparatus and method in one embodiment employs a plurality of collapsible, fluid chambers (120, 130), and associated means (140, 150) for controlling the fluid pressure in each of said chambers (120, 180). At least two of said chambers are physically arranged so that the inflation of one such chamber and deflation of the other complimentary chamber causes all or a part of the figure (110) to assume a different spatial position, dependant upon the level of inflation of each of said chambers. In another embodiment, a single, inflatable chamber is employed, said chamber having a section of one wall which is less elastic than the remaining portion of the wall. Due to the differential in elasticity, upon inflation the chamber assumes a shape or configuration which is different from the noninflated chamber. In a third embodiment, two collapsible, fluid chambers (540, 550) are provided. The chambers (540, 550) are each helically wound in opposite directions and placed substantially parallel to one another. Upon application of fluid pressure to either chamber (540, 550), rotation of that chamber occurs, causing the helical windings of that chamber to unwind while commensurately causing the other chamber to be more tightly, helically wound.
    • 一个实施例中的装置和方法采用多个可折叠的流体室(120,130)以及用于控制每个所述室(120,180)中的流体压力的相关装置(140,150)。 所述室中的至少两个物理地布置成使得一个这样的室的膨胀和另一个辅助室的通气导致图(110)的全部或一部分呈现不同的空间位置,这取决于每个室 的房间。 在另一个实施例中,采用单个可充气腔室,所述腔室具有一个比壁的剩余部分弹性小的一个壁部分。 由于弹性差异,在充气时,室呈现与不膨胀室不同的形状或构型。 在第三实施例中,提供两个可折叠的流体室(540,550)。 腔室(540,550)各自以相反方向螺旋缠绕并且基本上彼此平行地放置。 当向任一室(540,550)施加流体压力时,发生该室的旋转,导致该室的螺旋绕组放松,同时相应地使另一个室更紧密地螺旋缠绕。
