Abstract:
1. A device for movement and orientation of an object in space comprising: a fixed frame; a plurality of articulated connectors; a movable intermediate support connected to said fixed frame by said articulated connectors; an object support carried by said movable intermediate support; means for movement of the movable intermediate support relative to the fixed frame that maintains an orientation of the movable intermediate support relative to the fixed frame and comprises actuators for translation, along an axis, of an end portion of each of the articulated connectors carried by the fixed frame; and a parallel mechanism being configured for orientation of the object support relative to the movable intermediate support and comprising at least two assemblies for movement in rotation, each of the assemblies comprising: a control axle mounted rotatably on the movable intermediate support, a rotation actuator carried by the fixed frame, said control axle is driven in rotation by a respective said rotation actuator which is connected to the corresponding control axle by a transmission shaft mounted on cardan joints, and a first curved arm secured, at a first end, to the corresponding control axle and connected in an articulated manner to the object support at a second end, about at least one articulation axis, the control axle of each of the assemblies and the axis of articulation of each of said first curved arms having directions orthogonal to each other and intersecting in a point constituting a point of spherical rotation.
