Manipulator consisting from one sided self stop-ping mechanism and two masses which interact through an elastic – dissipative member is investigated. The drive of the manipulator is the generator of mechanical vibrations. With such elements the system is nonlinear. A separate case is investigated when static positions of equilibrium of both masses are located in one point. Because of this spec-trum of eigenfrequencies are linear and infinite. All those facts mean that the operation of the manipulator is optimal. Fast development of robots gives rise to the inves-tigations of increasing intensity creating various types of robots especially in the area of high precision. Mechanical systems of robot must perform laws and trajectories of motion, positioning in space with highest possible preci-sion as well as ensure dynamicity of highest possible sta-bility. Those aims are achieved in the presented paper by creating a structure of the best design, based on vibroim-pacts as well as by choosing corresponding nonlinear pa-rameters of the system. The investigation is performed by analytical – numerical method. The obtained results enable to create mechanical systems for precise robots.
