Abstract
A robot system includes an arm, one or more motors that move the arm according to a drive signal, a controller that controls the one or more motors, and an input section. The controller includes one or more sets including a filtering section that filters a position command to generate a filtered command and a drive signal generator that generates the drive signal using the filtered command. The filtering section includes a band-stop filter and a low-pass filter having a variable cutoff frequency. The cutoff frequency is set to a first frequency when an instruction to prioritize an operating speed is received, and the cutoff frequency is set to a second frequency lower than the first frequency when an instruction to prioritize suppression of vibration out of the suppression of vibration of the arm and the operating speed of the arm is received.
