    摘要: The invention is a robot teaching pendant containing a display device with graphic display capabilities. Display data is displayed on the graphic display and includes the movement of a robot and taught points. This display data is generated by a display data generation unit based on robot programs stored in data storage unit by buffering the data from a robot controller. This display data may also include representative images of the robot tool along with its coordinates in a tool coordinate system and the taught points in a user or world coordinate system. Thus, the action of the robot can be visually recognized with ease, and the robot can be taught easily and accurately.

    摘要: A robot control method capable of eliminating any influence of motion in a preceding path section to assure an accurate path movement with respect to a portion of a path section toward an end point. In a motion statement, a path-assurance section is previously designated in terms of length, time or path-assurance ratio for a moving path �2!.fwdarw.�3!. A path motion plan EFGH for the moving path �2!.fwdarw.�3! is created so that a path section represented by DHGK is the path-assurance section designated in the motion statement, assuming that D represents a terminal point of the motion along the moving path �1!.fwdarw.�2!. Consequently, an influence of motion of the moving path �1!.fwdarw.�2! is not exerted on the motion after a point in time represented by D or K, to assure a movement on the path �2!.fwdarw.�3! in the path-assurance section.

    摘要: First, an operator sequentially teaches the start point A, the end point F and junction points B, C, D, E on the welding path by moving the torch head by jog feed without paying attention to the torch orientation. Next, a reference plane to define the orientation of the torch is specified, and an inclination angle and a forward angle representing the torch orientation be inputted into a robot controller. On the basis of these inputted angle data and the taught data, a basic welding orientation is automatically calculated. Further auxiliary points are set around the junction points B through E each forming corner parts connecting straight lines; tool vectors which may give a smooth torch orientation change through the corner parts are automatically calculated for the auxiliary points and the junction points; and on the basis of the results, a welding program is produced. Among elements which determine the torch orientation, an element relating to the rotation around the torch axis reflects the state at the time of teaching of points A to E.

    摘要: An automatic nominal data setting method in a visual sensor system is capable of accurately and rapidly setting nominal data with ease, and a correction data deriving method is executable on the basis of the automatically set nominal data. If operation of the visual sensor system in a nominal mode is determined (S200) upon start of execution of an orientation portion of a user program by the visual sensor system mounted on an industrial robot, a message for interrogating whether or not nominal data setting should be executed is displayed (S201). When an operator inputs a nominal data setting command (S202), the workpiece position/posture data in the sensor coordinate system at that time, determined based on gray-scale image data, is converted into workpiece position/posture data in the robot coordinate system to be stored as nominal data (S203). During a robot operation, the visual sensor system calculates correction data for correction of the operating position/posture of the robot on the basis of workpiece position/posture data created similarly and the nominal data, and supplies same to the robot.

    摘要: A rack-and-pinion type steering gear for automotive vehicles including a columnar rack guide made of resin having a small coefficient of friction. An outer diameter of the rack guide in the direction perpendicular to the direction of movement of a rack bar is greater than an inner diameter of a rack guide hole for insertion of the rack guide in such a manner that the transverse cross-section of the rack guide is elliptical. With this arrangement, vibration of the rack guide in the rack guide hole due to an external force dynamically acting on the rack bar, thereby preventing generation of noise from the rack guide hole.
