“…As a suitable example of the mentioned behavior utilization of a motion reduction device can be studied when the high precision positioning with high payload is required. The common precise positioning device usually used a stepper motor with the positional encoder the no-backlash high ratio reduction gear and the ball screw [5], but the study [3] shows that the positioning errors from the ball screw are present. Consequently that the motion reduction compliant mechanism can be utilized as a device those potential positional errors can minimize (see Fig.…”

The paper is focused to design, simulation and modeling of the compact compliant structures widely used in construction of robotic devices. As the illustrative example it is proposed mechanism for reduction of motion, which enables to improve the accuracy of the positioning system. The physical model is fabricated by 3D printing technology. Its proposed performance characteristics are verified by measurement on the experimental test bed by using laser distance sensors and image sensing/processing technology.

“…For this reason, sensing the position of the levitating object is an important part for regulation needs. However, in order to design the necessary control, it is necessary to experimentally verify the position sensing by means of the optical shadow method [1][2][3][4][5][6][7][8][9][10].…”

Magnetic levitation used in technical applications such as transport systems in particular high-speed trains requires position control of the levitation system. It is precisely by suitable position control that there are no hazardous situations of contact of the mechanical parts outside the magnetic cushion, which can cause a dangerous state at very high speeds. However, for correct regulation, it is necessary to first turn out a reliable position sensing subsystem. It is precisely sensing the position using the optical method that this work is devoted to. The method of shielding is verified, when a smaller collimated beam falls on the photodiode. In order to measure the changes as accurately as possible, a laser collimating beam of light was chosen as the source.
