  • Patent number: 8874258
    Abstract: A method of transporting a substrate with a substrate support, the method includes defining a frictional breakaway force between the substrate and the substrate support in a horizontal plane, moving the substrate in the horizontal plane along a horizontal trajectory, moving the substrate in a vertical direction along a vertical trajectory simultaneously while moving the substrate in the horizontal plane, and wherein the horizontal trajectory is determined based on the acceleration profile of the vertical trajectory and wherein the horizontal trajectory prevents the moving of the substrate from overcoming the coefficient of friction in the horizontal plane.

  • Publication number: 20140017056
    Abstract: A substrate transport apparatus including a lower linearly driven effector structure with spaced paddles, and an upper linearly driven end effector structure with spaced paddles and no rotating joints above a paddle of the lower end effector structure. A drive subsystem is configured to linearly drive the lower end effector structure and to linearly drive the upper end effector structure independent of the lower end effector structure.

  • Publication number: 20140007731
    Abstract: A robot arm includes a wrist, an end effector, and an adjustable joint coupling the end effector to the wrist. The adjustable joint includes a member received in a socket. In one example, the member is a ball. In another example, the member is a tang. In both examples, an upper flange and a lower flange can be used to couple the wrist to a forearm.

  • Publication number: 20140009025
    Abstract: A hybrid field electric motor includes a rotor with a rotor core rotating about an axial axis and having a rotor surface with at least one sloping edge face and a radial edge face. The stator includes a stator core and radial pole faces spaced by a gap from the radial edge face of the rotor for radially directing flux into the rotor core. The stator has sloping pole faces spaced from the sloping edge face of the rotor core for flux directed into the rotor core at an angle between radial and axial. The rotor core and/or stator core are made of a soft magnetic composite material for flux in inure than one plane in the core(s).

  • Publication number: 20130294877
    Abstract: A vacuum robot adapted to grip and transport a substrate. The robot includes a robot drive coupled to an arm and having an end-effector adapted to support the substrate. A robot gripper system is coupled to the end-effector including a front support having at least one hard stop, a movable contact element coupled to the end-effector, a bias device coupled to the contact element, and at least one actuator coupled to the end-effector configured to move the contact element between a release position and a grip position. The bias device is configured to passively bias the contact element in the grip position such that the contact element contacts an edge of the substrate to urge the substrate against the at least one hard stop to secure the substrate in the grip position and to passively bias the contact element in the release position such that the contact element is retained in the release position.

  • Publication number: 20130085002
    Abstract: A transport system includes, in a first environment, a driving screw having threads with a thread pitch. In a second environment, a driven member has a magnetic coupling with a driven member pitch substantially corresponding to the thread pitch. The magnetic coupling is coupled to a portion of threads and rotation of the driving screw displaces the magnetic coupling with respect to the driving screw.
