Introduction− This paper introduces the design and the construction of an electromechanical slider that allows obtaining the instantaneous speed and acceleration of a platform that holds a scientific camera to take photos for the study motion-blurred images. The mechanical and electrical design requirements are given based on the conditions of presentation of the phenomenon. The system was calibrated concerning a standard instrument for the estimation of the uncertainty and error.
Objective− In this paper, the design, construction and calibration of an electromechanical system for the study of images with uniform motion blur is presented.
Methodology− The development of the system is split into the following steps: The design and construction of an aluminum electromechanical slider built with a mobile platform that moves at constant speed; the calibration of the speed of the mobile platform using the Guide to Estimate Uncertainty in the Measurement (GUM); and the design and construction of the electromechanical aluminum slider mounted with a mobile platform at constant acceleration and the calibration of the mobile platform for the acceleration applying the Guide for Estimation of Measurement Uncertainty (GUM).
Results− Maximum uncertainties of were obtained for speed and for acceleration of the system.
Conclusions− The developed system corresponds to an electromechanical system that allows to move a cart along a pair of parallel bars, of low uncertainty with the possibility of measuring instantaneous speed and acceleration for the study of motion blurred images and teaching of motion physics.
