Abstract: A positioning device includes a planar surface, a mobile platform configured to slide along the planar surface and cables for positioning and moving the mobile platform along the planar surface. The mobile platform includes a planar bearing system located at the side of the mobile platform configured to slide along the planar surface. The planar bearing system includes a component for pushing the mobile platform against the planar surface; and a component for allowing sliding of the planar bearing system with respect to the planar surface.

Abstract: A platform for a parallel robot, for acting on an object, including: at least two frames comprising at least two pairs of swivels; at least two bridges that are connected to each of the frames respectively by four hinges which are substantially parallel to an axial direction (V); and a base to be connected to an effector, which is suitable for acting on the object. The base is connected to each bridge respectively by at least one hinge which is oriented along a connection axis which is substantially parallel to the axial direction.

Abstract: The invention refers to a two degree-of-freedom parallel manipulator that comprises a frame (1), four frame arms (3, 3?, 4, 4?), four platform arms (5, 5?, 5?, 5??), each frame and platform arm (3, 3?, 4, 4?, 5, 5?, 5?, 5??) with a first end and a second end, a platform (6) and a end-effector, being the first end of each frame arm (3, 3?, 4, 4) linked to the frame (1) and being the second end of each frame arm (3, 3?, 4, 4?) linked to a first end of a platform arm (5, 5?, 5?, 5??), being the second end of each platform arm (5, 5?, 5?, 5??) linked to the platform (6), and being the platform (6) linked to the end-effector. In said manipulator a first platform arm (3) and a second frame arm (3?) are actuated independently one from the other and a third frame arm (4) and a fourth frame arm (4?) are linked to the frame (1) with revolute joints (8), being the rotation of the third and fourth frame arms (4, 4?) coupled.
