To improve the working efficiency by reducing the working hours of a robot system.

This robot system 1 includes: a plurality of robots 2, 3; and a control device for controlling the drive of the respective robots 2, 3, wherein the control device 4 includes: a work information storage means 43; an interpolation operation period storage means 43; an analysis means 45; an interpolation point position operation means 46; interpolation point position information storage means 43, 48; a drive control means 49; and a determination means 47, and the drive control means 49 stops transmission of the n-th (n is a natural number) interpolation point position information 43d to the respective robots 2, 3 when the determination means decides that the space between the n-th (n is a natural number) interpolation point position from the moving start position of one robot 2 and the n-th (n is a natural number) interpolation point position from the moving start position of a second robot 3 is under a predetermined space.
