Abstract: A three-dimensional printing system includes a printing tool, a control arm, and a mounting rack. The printing tool includes a rigid base on which an object is configured to be printed. The control arm is removably connected to the rigid base and is configured to move the rigid base. The mounting rack is configured to store a plurality of printing tools. The mounting rack includes a support member and a plurality of recesses disposed in the support member. Each of the plurality of recesses is configured to receive one of the plurality of printing tools. A plurality of first openings is disposed in the support member and surrounds each of the plurality of recesses. A magnet is disposed in one of the plurality of first openings. A spring ball plunger is disposed in another one of the plurality of first openings.

Abstract: A three-dimensional printing system includes a tank, a guide rail, an arm, a rigid base, and a light source. The tank contains a liquid photopolymer resin. The guide rail is mounted externally of the tank. The arm is movably connected to the guide rail. The arm is configured to be movable relative to the tank along the guide rail. The rigid base is connected to the arm. The light source is configured to emit light to the tank to form an object on the rigid base.

Abstract: A three-dimensional printing system includes a tank, an arm, a rigid base, a light source, and a calibration tool. The tank contains a liquid photopolymer resin. The arm is configured to be movable relative to the tank. The rigid base is connected to the arm. The light source is configured to emit light to the tank to form an object on the rigid base. The calibration tool is connected to the tank. The calibration tool is configured to calibrate at least one of the tank and the arm.

Abstract: System and methods for jogging a robot end-effector in constant awareness. On a graphical user interface is displayed, dynamically in real-time while the robot is moving, a current position and a relative indicator for the current position for each of a plurality of joints of the robot. A position of the relative indicator for each of the plurality of joints is proportional to an actual position of a corresponding joint with respect to physical limits thereof. Is also displayed three or more input elements, each having clickable buttons at extremities thereof and a thumb marker movable along at least one of a curvilinear track and across an area. Each of the three or more input elements is associated with at least one of: one or two of the plurality of joints of the robot and one or two degrees of freedom of the robot end-effector.

Abstract: A planar parallel mechanism having a platform movable in a plane along three degrees of freedom is described Existing technology fails to provide a manipulator with three degrees of freedom, wherein the mechanisms for moving the manipulator move in a decoupled fashion A manipulator and method of supporting and displacing an object which provides a solution to this problem comprises a base (1) and a moving portion (2) and articulated support legs (A1,A2,A3) between the moving portion (2) and the base (1) The articulated support legs (A1,A2,A3) are connected to the base (1) by a first translational joint, and jointly restrict movement of the moving portion to displacements in a plane in two translational degrees of freedom and one rotational degree of freedom A decoupled displacement of the moving portion (2) along a first of the two translational degrees of freedom and a decoupled displacement of the moving portion (2) along the rotational degree of freedom both result from actuation of at most two of the firs

Abstract: A manipulator for supporting and displacing an object comprises a base. A moving portion supports the object. Two articulated mechanisms each having five rotational joints between links, with each articulated mechanism being connected to the base by two of the rotational joints. The moving portion is connected to both the articulated mechanisms by moving-portion joints. The articulated mechanisms and moving-portion joints are arranged with respect to each other between the base and the moving portion so as to constrain movement of the moving portion to displacements in two translational degrees of freedom and two rotational degrees of freedom with respect to the base. Four actuators are each operatively connected to a different one of the rotational joints between the base and the articulated mechanisms so as to selectively control the displacements of the moving portion in any one of the four degrees of freedom of the moving portion.
