The controlled motion of systems of bodies along a straight line on a rough plane is studied. In the first part of the paper, we consider a systems of two mass points connected by a spring. The system is driven by forces that act between the points and change harmonically. To provide the asymmetry of the friction force, necessary for the progressive motion in a given direction, it suffices to apply a brush-like or scaly coating to the contact surfaces. In the second part, we consider a rectilinear motion of a vibration-driven system, consisting of a housing body and two internal masses, along a rough horizontal plane. One of the internal masses oscillates in the horizontal direction and the other oscillates vertically. It is shown that by changing the phase shift between the horizontal and vertical oscillations one can control the velocity of the steady-state motion of the systems, for symmetric or asymmetric friction. In the third part, the motion of two mass points connected by a spring and actuated by two unbalance rotors is investigated. It is shown that the direction of motion of the systems can be changed by changing only the magnitude of the speed of the rotors, with the direction of rotation kept unaltered.
