In this paper, we propose modeling and visualization of the pipe movement trajectories in a pipe bending machine. Mathematical equations for converting quaternion data to Euler angular data are presented. The paper uses the method of double integration on the acceleration data from the IMU-9250 MEMS sensor to obtain realistic speed and location. The program is implemented in the MATLAB environment for visualization of pipe trajectories in 3D representation.

This article analyzes the problem of precise control of the laser beam. The optical signal may deviate and affect the environment. The analysis of the steering system is based on some important factors for designing the structures of the fast steering mirror and the steering system with laser optics. A 4-quadrant detector is used as a sensor for the input light. The design of the developed control loop and the concept of the mirror model are discussed.
