    摘要: An electric actuator includes a motion conversion mechanism and a position detector. The motion conversion mechanism converts rotation of a rotary shaft of a motor into linear motion of an output shaft. The position detector detects a permanent magnet M, which moves integrally with the output shaft. A motor control portion controls the motor based on commands from a host command unit. A control program for controlling the motor includes, as control modes, six fluid pressure cylinder modes, according to which the motor is controlled. Specifically, each of the control modes corresponds to one of the cases where the fluid pressure cylinder is controlled by three solenoid valves, or a two-position single solenoid valve, a two-position double solenoid valve, and a three-position double solenoid valve. The motor is controlled according to the selected control mode.

    摘要: A multi-axis robot and controller therefor which is responsive to the input of target position information for each of plural axes and outputs position commands to motors for each axis of the robot. All of the axes are considered together and are assumed to move according to the same velocity profile, the fastest velocity is identified and used as the basis for assigning a relative load factor to each axis. An actual velocity command for movement of each axis according to the input target position is calculated on the basis of the preceeding position command, its load factor, velocity profile and interpolated velocity value. The position command is calculated on the basis of the velocity command. The controlled axes may include additional outside axes and the load factor may be variable.

    摘要: A robot operating method capable of easily performing manual correction of a previously taught teaching point during an automatic robot operation, and of accurately and effectively performing a desired robot operation without the need of employing a visual sensor. After switching is made from an automatic operation mode to a manual operation mode in response to reading of a predetermined command code from a program (S1, S2), a robot tool positioned at a first teaching position is moved to a first working position on a workpiece by a control apparatus which responds to an operation of a remote operation board by an operator, so as to compensate for a dislocation of the teaching point attributable to a positional dislocation of the workpiece (S3), and then a correction data indicative of the results of a manual adjustment is calculated in response to supply of an external signal generated by an operator's operation and is stored in a memory (S4, S5). After completion of robot working at the first working position, second and later teaching points are sequentially corrected based on the correction data in response to reading of a position correcting command code from the program, whereby the robot working is accurately carried out at second and later working positions on the workpiece.

    摘要: An automatic manipulator capable of performing various programs and adaptively controlled operations with respect to work including operations on work. Automatic tool changing means are provided wherein the manipulator changes tools with respect to its tool holding fixture, tool head or heads. In one form, a plurality of tools to be used are supported on a rack adjacent the manipulator and the manipulator is automatically operated to effect the uncoupling of one or more tools from its operating head and the coupling of one or more tools with respect to such operating head. In another form, the tools are supported by the manipulator itself and the manipulator is automatically controlled to effect the transfer of tools between its operating head and a storage location for the tools. In a third form, tool heads themselves are automatically changed and received either from storage on the manipulator or adjacent the manipulator. In a fourth form, the tool head is composed of a turret containing a plurality of different tools and manipulating devices, which turret is automatically operated to bring a selected tool or fixture into an operative location on the manipulator.

    摘要: A method and apparatus by which correct tool dimensions for a three dimensional tool mounted on a manipulator can be determined. The manipulator operator inputs initial values for the tool dimensions into the manipulator control in the teach mode. Having established a target point within the manipulator's working volume, the operator, by means of teach pendant, causes the tool center point to approach and touch the target point from four different directions, at least one of which is noncoplanar with respect to the other three. For each approach point coordinates X, Y, Z, D, E, R are entered into the control. The control thereafter executes an analytical procedure including a major iteration loop which calculates the coordinates of the target point. In a first minor iteration loop within the major iteration loop updated tool dimensions are derived. In a second minor iteration loop within the major iteration loop new coordinates for the tool center point approach points are calculated. The differences between the average of the calculated coordinates of the target point and the average of the calculated coordinates of the approach points are determined. If the differences fall within operator determined limits the tool dimensions calculated in the first minor iteration loop are used. If not, the major iteration loop is repeated using the calculated values the tool dimensions and approach point coordinates of the previous iteration until they do, or until a predetermined number of iterations has been performed, whereupon an error signal is displayed.
