A motor arrangement includes a stator body, a rotor body, a permanent magnet and a fluid conduit. The stator body defines a rotary axis and has a bore. The rotor body is supported for rotary movement about the rotary axis in the bore and is separated from the stator body by a gap. The permanent magnet is arranged within the gap and is fixed to one of the stator body and the rotor body. The fluid conduit is supported above the gap and has an outlet in fluid communication with the gap to separate the permanent magnet from an infiltrant fluid resident within an atmosphere above of the gap by issuing a barrier fluid into the atmosphere above the gap and gravimetrically flowing the barrier fluid into the gap. Semiconductor processing systems, barrier fluid kits, and methods of purging motor arrangements are also described.

A robotic joint has a first portion that includes a first actuator and a second actuator, a first spherical linkage having a first end mechanically coupled to the first actuator and a second end mechanically coupled to a second portion of the robotic joint, and a second spherical linkage having a third end mechanically coupled to the second actuator and a fourth end mechanically coupled to the second portion. The first and second spherical linkages are segments of a spherical shell. The first and second actuators are operable in combination to control movement of the second portion relative to the first portion with two degrees of freedom. Each actuator causes a first respective movement in the same direction as each other to control a flexion or an extension, and a second respective movement in opposite directions to each other to control an abduction or an adduction.

The present system and method provides for a new digital media paradigm enabling tight choreography of motion, content and, time able to be presented on a variety of hardware platforms consisting of robotic control of a multiplicity of display screens in the form of a movable array of 2 or more LCDs, LEDs, OLEDs, etc., with the movement and placement of each display achieved by one multi-axis manipulator arm mechanism. Motion control is achieved through software programmed onto one or more controller systems, and the corresponding tools necessary for creative visual designers to produce content meeting this new paradigm are also proposed. Each arm/display screen combination is kept aware of its positioning in physical space, relative to the positioning of each and every other arm/display screen at all times, in order to prevent collisions. The pre-programmed software control takes the form of a choreographed playlist of movements, content, and time that match the desired positioning of the array of display screens, in order to achieve the desired dynamic presentation of custom produced digital content that will be presented across the array, in a fully coordinated fashion.
