Robot system, control device of robot, and robot control device

In a method for adjusting parameters of impedance control, an overshoot amount allowable value is set as an allowable maximum value of an overshoot amount of a time response of a force feedback from a force sensor provided for an end effector of a robot manipulator, and a setting time allowable value is set as an allowable maximum value of a setting time of the time response of the force feedback. A viscosity parameter with which the setting time is shortest is calculated while fixing the inertia parameter. An overshoot amount adjustment value and a setting time adjustment value which are obtained from a result of the calculating of the viscosity parameter are compared with the overshoot amount allowable value and the setting time allowable value, respectively, to determine whether a repeating process is finished or continued.

Robot, robot system, robot control device, and state determining method

An apparatus has a parameter initial value calculator, a force reference impression part, an evaluation data measurement part, an allowable value setting part, a viscosity parameter calculator, an end determining part, and an inertia parameter adjusting part. The force reference impression part intermittently supplies a force reference to an impedance controller.
