Analysis of the Position Error and Displacement Parameters of Ideal and Real Mechanisms for Robotic Systems

The elements of kinematic pairs most often used in the design of mechanisms are considered. Possible primary errors for a point, line, plane, spherical pair, sliding pair, and turning pair are presented. The number of primary errors of a connecting rod with elements of two rotational pairs are calculated. Calculation of a cam mechanism is carried out. Recommendations for identifying primary errors in the mechanisms of robotic systems are presented.
