The system has arms (A1,2,3) connected relatively moveable via joints (G1,2,3), and an actuator unit with coupler mechanism. The mechanism acts with a rotary drive transmission (R1,2) having a drive body and a take-off body. The drive body is moved by a slide part of the mechanism. The take-off body is fastened to the second cantilever arm in such a way, that these are turnable coaxially and synchronously only.
