  • Publication number: 20210216048
    Abstract: A vibration suppression device that suppresses vibration of an operation unit in a mechanical system having a natural vibration mode including the operation unit, an actuator unit that operates the operation unit, and an elastic body that couples the operation unit and the actuator unit, the vibration suppression device including a generation means for generating a drive signal for driving the actuator unit, an estimation means for estimating a measurement amount related to the mechanical system, a correction means for correcting the drive signal generated by the generation means on the basis of the measurement amount estimated by the estimation means, and a change means for changing a gain used by the estimation means so that an influence of an increase in a modeling error becomes small in a period in which the modeling error of the mechanical system increases.

  • Patent number: 10737346
    Abstract: Provided is a welding robot mechanism that has: a welding robot having a touch sensing function; a welding power source for supplying welding power to the welding robot; and a control unit for controlling the welding robot, wherein the welding power source has a welding power source communication unit that receives detection signals with regard to control of the welding robot and the touch sensing, and transmits the detection signals outward. The control unit is linked to the welding power source communication unit via a serial bus communication wire. The detection signals comprise a mass of data including a detection data group designated as a first group and a detection data group designated as a second group, and is configured to read the detection data group designated as the first group in a shorter cycle than that for the detection data group designated as the second group. The detection data group designated as the first group includes a detection signal obtained by the touch sensing.
