    • The present invention relates to a method and a device for machining an object by means of a tool, wherein the tool (2) or the object (18) is guided with a handling device, which has multiple axes of movement for the rough positioning of the tool (2) or object (18) forming a kinematic chain. According to the method, an additional actuator (3) is inserted between an end link (1) of the kinematic chain and the tool (2) or object (18), the actuator having greater actuating accuracy than the other axes of movement in at least one dimension or axis. At least one sensor (5) is used to detect a relative movement of the tool (2) or end link (1) of the kinematic chain to the object (18), and any deviation from a target path of movement is compensated for by means of the additional actuator (3). The method and the associated device enable the use of robots or other handling devices having low path accuracy for applications requiring high precision in guiding the tool.

    • Known component bearings either use six parallel double-jointed members (hexapods) that while being adjustable with six degrees of freedom and high accuracy can only be adjusted in mutual dependency of one another, or double-jointed members that are mounted in series via connecting bodies and whose joints can be rotated about one axis, that allow only two rotational deflections, under error summation, and that meet in a virtual point as the point of origin of a Cartesian coordinate system. The aim of the invention is to design a bearing that allows a movement of the component in all six degrees of freedom in a highly accurate, reproducible manner while maintaining the axial rigidity of the component. To this end, six parallel double-jointed members (2J1, 2J2, 2J3, 2J4, 2J5, 2J6) comprising two joints (J1, J2) each that can be rotated about three axes are distributed in the coordinate planes (XY, XZ, ZY) in such a manner that the rotational (xrot, yrot, zrot) and translational (xtrans, ytrans, ztrans) deflections can be achieved by adjusting, if possible, only one double-jointed member (2J1, 2J2, 2J3, 2J4, 2J5, 2J6) ( defined adjustment ). The joints (J1, J2) preferably used in the double-jointed members (2J1, 2J2, 2J3, 2J4, 2J5, 2J6) are flexible joints (J1, J2), especially elastic fiber joints. The inventive joints can be used in bearings of optical components, especially mirrors.

    • A robot has a robot arm, a support structure, and a movable platform. The platform includes a cantilevered member coupled to a guide of the support structure such that motion of the platform is directed along a first direction. The robot further includes first and second timing belts having portions that extend along the first direction and that are disposed on opposite sides of the cantilevered member, and first and second shafts movable with the movable platform. The shafts are coupled to the respective timing belts, to the robot arm such that rotation of the first shaft imparts angular motion to the robot arm and rotation of the second shaft imparts radial motion. The robot also includes a third timing belt to which the platfopn is coupled and by which it is moved. Motors are provided that impart movement to the timing belts.
