A telescopic system including a plurality of modules. Each of the modules includes a case, a nut, and a screw. The nut is freely rotatable in the case and is prevented from translating with respect to the case. The screw is engaged with the nut, and each of the cases is mutually freely slidable and prevented from rotating with respect to each other. The modules are arranged in a chain, and adjacent modules in the chain are interconnected by a rotation transmission coupling. The rotation transmission coupling is between one of the screw and the nut of the adjacent modules. Each of the modules includes a rotation transmission link between the screw and the nut.
