Publication number: 20240033909Abstract: The present invention improves a vibration-dampening effect produced through learning in a state during production on a user side. This control device, which prepares a correction amount for controlling the operations of a robot, comprises: a learning control unit that has a parameter used in a learning control for preparing the correction amount; a parameter storage unit that stores a parameter set prior to shipment; and a parameter adjustment unit that, during production by the robot, adjusts the parameter stored by the parameter storage unit and sets the adjusted parameter in the learning control unit. The parameter adjustment unit adjusts the parameter on the basis of, e.g., the multiplicative inverse of a frequency response characteristic of the robot. The parameter adjustment unit also adjusts the parameter according to, e.g., a genetic algorithm.Type: ApplicationFiled: August 16, 2021Publication date: February 1, 2024Inventors: Kouichirou HAYASHI, Hajime SUZUKI
