Abstract: A security check instrument motion control system includes an FPGA control chip that receives motion instructions, comprising angle, direction, speed and the like, from an upper computer via an upper computer communication module, realizes quick control to a rotation motion module, and controls a motion state of the rotation motion module according to real-time motion information of the rotation motion module detected by a positioning detection module. The motion state includes a motion stop state and a normal rotation state. The FPGA control chip detects the working state of each module in the security check instrument motion control system in real time, and once the security check instrument motion control system has a fault, each module can be subjected to debugging, repairing and maintenance respectively. If the positioning detection module detects that the rotation motion module is abnormal, the FPGA control chip controls the rotation motion module to stop moving.

Abstract: A combined system having a function for rapidly detecting and correcting a positional misalignment between a machine tool and a robot. The combined system includes: a machine tool having a table and a workpiece fixing jig integrally movable with the table; a robot system separated from the machine tool and having a robot configured to supply or take out a workpiece to or from the jig; a network for information transmission between the machine tool and the robot; an interference judging part which judges occurrence of interference, based on a disturbance value of each axis of the robot, when the workpiece is supplied to or taken out from the jig; and an interference avoiding part which, when it is judged that the interference occurs, stops a motion of the robot and moves the table in a direction of at least one axis based on the disturbance value.

Abstract: A method for controlling a screwing process, includes during the screwing process screwing a screw into a component with an electrical screwing device; detecting during the screwing process an actual course of at least one process parameter of the screwing; testing whether the actual course has a pattern which predicts an error of the screwing process; and terminating the screwing process early when the actual course has said pattern.

Abstract: A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine. The system includes a computer aided design (CAD) file processing portion, an inspection motion path generation portion and a user interface. The user interface includes a workpiece inspection program simulation portion and auxiliary collision avoidance volume creation elements. The workpiece inspection program simulation portion displays a 3D view and the auxiliary collision avoidance volume creation elements are operable to create or define auxiliary collision avoidance volumes that are displayed in the 3D view. In various implementations, rather than requiring a user to model a physical object (e.g., as part of a workpiece or CMM) in a CAD file, the user may instead create and position an auxiliary collision avoidance volume at a location where the physical object is expected to be, so as to prevent collisions that could occur with the physical object.

Abstract: A system and method are provided for facilitating hands free and precise movement, translation and repositioning of a movable mechanical apparatus, including an operating room lighting system, mounted to a mechanically-movable base component including, for example, an articulable or articulated robotic-type arm, according to user input pointing commands, including laser or other like pointing commands initiated by a user. The user provides hands free designation of a point of focus with a pointing device. A sensor associated with the movable mechanical apparatus automatically detects the designated point of focus and a processor determines and executes a scheme of movement for moving the movable mechanical apparatus from a current position to a position proximate to the designated point of focus. A collision avoidance scheme is also provided for safety and to alert the user as to the presence of any impediment in the determined scheme of movement.
