    摘要： A parallel mechanism for manipulating an object in space is provided. The parallel mechanism includes an end platform for supporting an object to be manipulated and an intermediate platform arranged in spaced relation from the end platform and connected to the end platform by a connecting element. A plurality of first links are connected to the end platform and a plurality of second links are connected to the intermediate platform. A linear motor is associated with each first link and each second link for translating the ends of the first and second links to move the end and intermediate platforms.

    摘要： A manipulator for producing a remote center of revolute motion is provided. The manipulator includes a base and a first parallelogram linkage mechanism including a first link pivotally mounted to the base for rotation about a first axis such that the first link moves in a first plane. The manipulator also includes a second parallelogram linkage mechanism including a second link pivotally mounted to the base for rotation about a second axis such that the second link moves in a second plane parallel to the first plane. The first link is pivotal about a third axis perpendicular to the first axis and the second link is pivotal about a fourth axis perpendicular to the second axis. The first and second parallelogram linkages are pivotally connected together by a first connector link and a second connector link. The first and second connector links are parallel to each other and parallel to the first and second axes such that the first and second planes remain parallel as the first and second links respectively rotate about the third and fourth axes. A tool holder is pivotally connected to the first connector link by a first pivot joint and pivotally connected to the second connector link by a second pivot joint such that a tool held therein is pivotable at a remote virtual pivot point about a first remote pivot axis by pivoting the first and second links respectively about the first and second axes and a second remote pivot axis by pivoting the first and second links respectively about the third and fourth axes.
