    Abstract: The invention relates to a device for reducing oscillations of a robot. An acceleration pattern is subjected to Fourier transform to provide a power spectrum distribution. A component of a resonant frequency (fn) is removed from the power spectrum distribution to provide a further power spectrum distribution for redeeming an acceleration pattern. The acceleration pattern thus found is integrated to provide a speed pattern. Then an acceleration and deceleration time corresponding to a taught velocity is found, and various axes of the robot are controlled in accordance with the velocity pattern which corresponds to the acceleration and deceleration time thus read out.

    Abstract: A method of controlling an industrial robot, wherein vibrations and out-of-path of the forward end of a tool can be prevented when the tool mounted to the forward end of a movable arm is moved along a taught path, and a working position and an attitude of the forward end of the tool can be accurately and smoothly controlled to specified ones. The controlling method comprises the steps of: comparing a moving time (Tm) required for the forward end of the tool to move at a taught moving speed (VT) between preset two taught points (P1, P2) with the maximum value (T1) obtained from respective moving times of respective articulated shafts of the movable arm, which are obtained from moving amounts and limit speeds of the respective articulated shafts of the movable arm between the above-described taught points, before having the robot execute a moving command; recalculating a taught speed in accordance with which of the former and the latter moving times is longer; and executing the moving command by use of the recalculated taught speed (V), so as to limit the moving speed of the forward end of the tool.

    Abstract: A control device for a work carrying system characterised in that a first point where the moving action of a work transitions from a moving action from an origin process chamber to a transfer chamber to a moving action inside the transfer chamber and a second point where the moving action of the work transitions from the moving action inside the transfer chamber to a moving action from the transfer chamber to a destination process chamber are set on a moving path of the work, and that speed patterns on the moving path are set based on a moving distance of the work and time required to open and close gate means of the origin and destination process chambers such that the opening of a gate valve at the destination is completed when the work reaches the second point on the moving path and that a moving time from the first point to the second point becomes the shortest time which is longer than the opening and closing time of the gate valve, the speed of a work carrying robot being thereby controlled in accordance with the set speed patterns, whereby any chance of the robot being temporarily stopped is minimized so as to effect high-speed carrying of a work such as a wafer requiring a shortest possible carrying time.

    Abstract: An apparatus for controlling weaving welding by a robot in a high precision. Driving controllers (5, 6 and 7) drive each of the shafts of the robot in accordance with an input signal corresponding to a calculated target position theta 1d. The transmission function G(s) of at least one predetermined shaft among those of the robot, for the driving controllers (5, 6, 7), is calculated. The calculated target position theta 1d of the predetermined shaft is multiplied by the inverse transmission function 1/G(s) which is obtained from the transmission function thus calculated. In this way, a corrected calculated target position theta 1d* is obtained. A signal which corresponds to this corrected calculated target position theta 1d* is inputted into the drive controllers (5, 6 and 7). As a result, both the resonance characteristic (gain characteristic) and phase characteristic at an arbitrary weaving frequency are compensated. Thus, the precision of the weaving amplitude at the nose of the torch is enhanced, and at the same time, the distorsion of the weaving surface and waveform is significantly improved.

    Abstract: An untaught robot can be put into a servo-off state without fail and teaching of a plurality of robots disposed in an area interfering with each other can be safely performed. Moreover, only one teaching device is enough and the teaching can be performed without confusion. For these purposes, in a double arm robot provided with first and second robots (3a, 3b) operating with each interfering area on each side of a strut (2), the teaching of the plurality of robots can be safely performed by connecting controllers (4a and 4b) of the both robots (3a and 3b) to a teaching device (5) through a change-over switch (6) such that, when one of the controllers (4a and 4b) of the both robots (3a and 3b) is connected to the teaching device (5), the other is disconnected.
