A remote center compliance system having a variable center having an upper plate and a lower plate, and a plurality of elastic bodies installed between the upper and lower plates, includes a plurality of lower rotary plates, each having a rotation axis parallel to a center axis passing the center of the lower plate and the center of the upper plate, and coupled to a lower end of each of the elastic bodies and coupled to the lower plate to be capable of rotating, and a plurality of upper rotary plates, each being coupled to an upper end of each of the elastic bodies and concurrently coupled to the upper plate to be capable of rotating about the rotation axis of the lower rotary plate, in which a center axis of each of the elastic bodies is inclined with respect to the rotation axis of the lower rotary plate to which each of the elastic bodies is coupled. Thus, when parts having different lengths are to be assembled, the assembly of the parts can be easily performed by only rotating the rotary plates and the elastic bodies by a predetermined angle without changing the RCC system to cope with various lengths of the parts. That is, the time and cost for the assembly process can be reduced.
