Abstract:
A robot system includes a robot having an arm pivoting about a pivot axis (first pivot axis), a motor (first motor) pivoting the arm, a shaft (spline shaft) coupled to the arm and moving in an axial direction of a linear motion axis parallel to the pivot axis, and an inertial sensor provided in the arm or shaft, and a control apparatus having a control unit controlling the motor, wherein the inertial sensor detects an angular velocity about a roll axis orthogonal to the pivot axis and the linear motion axis or an acceleration in a tangential direction of a circle around the roll axis, and the control unit controls the motor based on information representing a pivot direction of the arm about the roll axis when the arm stops or decelerates and output from the inertial sensor.
