This paper analyses the movement of piezoelectric actuator. The goal of this work was to create an algorithm for trajectory planning of piezorobot, create a system for trajectory control, develop software and verify the functioning of the algorithm in practice. Movements of piezorobot are very small and very frequent therefore it is difficult to measure trajectories using standard equipment. Design of a novel measurement system and trajectory adjustment was created in this paper. An experimental system for control and trajectory movement tracking of piezorobot was developed. It consists of cylindrical piezorobot, control signal forming and image processing system for trajectory tracking. The cylindrical piezorobot moves in specific trajectories on the plane and is controlled with sinusoidal signals. They are generated by trajectory forming and control software using MATLAB and LabVIEW. The control signals are monitored using a system with oscilloscope. The trajectory of piezorobot was monitored and measured using video camera and video processing software developed by LabVIEW. The software contains image processing and object path tracking, and is implemented using LabVEW and MATLAB. Experimental results showed that trajectories forming algorithm and developed control software is suitable for controlling robots moving on plane.

Practice shows that the best built and maintain by the knowledge, is based on and secured personal work experience. Source of expertise can be carried out e-laboratory theoretical and practical experiments. The study key is the development of the system will hamper its inappropriate use. There is a lack of e-tools that enable students to deal with the challenge, problem or phenomenon monitoring experiments t. y. entering or selecting the initial data. New technology, especially electronic, progress is very important because it allows the development of continuing education, distance education, the democratization of it, adapting to people with different capabilities and needs. Discussed problem is creating a different type of laboratory. The key novelty is that it is not a virtual laboratory based on software tools, but the real remote-controlled electronics lab. Produced simplified conceptual model for remote laboratory experiments and demonstration. The article describes a real remote e-laboratory designed and applied in Vilniaus kolegija/University of Applied Sciences as an experimental practical method for distance learning.

The article analyses the application of automatically controlled physics laboratory experiment using information technology to enhance students’ motivation and interdisciplinary communication. The paper reveals how the application of interdisciplinary methods promotes students’ interest in studies, enhances the learning process and the quality of the students’ learning results from the very beginning of learning process. It was practically justified that during the fundamental science laboratory experiments, the first-year students realistically assess their future career prospects. Students become aware of the perspective of the further studies because they work with equipment designed by higher courses students. As a practical illustration of the authors and students of physics experiment designed automated equipment. The experiment system realized combines mechatronics, electronics, and programming technical areas corresponding to students' professional specialization. The system of physics laboratory experiment, has attracted particular interest students and the author conviction increased student motivation to learn.

New trajectory planning method for mobile piezorobots is presented in this paper. Non-rotated mobile piezorobots must move by the given trajectory at the maximum speed and precisely replicate the given path. Two segments excitation schemes, which are used for formation of motion trajectory, were analyzed. Trajectory planning method was verified with numerical experiments and with the experimental system in the laboratory.
