Выполнены построения скоростной плоскости и скоростного пучка при полученных мгновенных значениях обобщенных скоростей на примере заданного синтеза малых движений механизма антропоморфного робота. Синтез движений основан на использовании матриц частных передаточных отношений с использованием критерия минимизации квадратичного функционала объема движения. Графический анализ составляющих векторов абсолютных линейных скоростей трех точек подвижной системы позволил определить способ расчета промежуточных конфигураций руки антропоморфного робота, основанный на использовании весовых коэффициентов обобщенных скоростей. Представлены результаты расчетов тестового задания при компьютерном моделировании движения антропоморфного робота.</p></abstract><trans-abstract xml:lang="en"><p>The analysis of instantaneous states of the moving system connected with the output link of the anthropomorphic robot is carried out based on the use of graphical constructions performed on the frontal and horizontal projections. The constructions of the velocity plane and the velocity beam are performed for the obtained instantaneous values of generalized velocities using the example of the given synthesis of small motions of the robot mechanism. The synthesis of movements is based on the use of matrices of partial gear ratios using the criterion of minimizing the quadratic functional of the volume of movement. The graphical analysis of the components of the vectors of absolute linear velocities of three points of the moving system made it possible to determine the method for calculating intermediate configurations of the arm of the anthropomorphic robot based on the use of weight coefficients of generalized velocities. The results of calculating the test task in computer modeling of the movement of the anthropomorphic robot are presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>механизмы манипуляторов</kwd><kwd>мгновенные состояния механизмов</kwd><kwd>вектор обобщенных скоростей</kwd><kwd>графические построения скоростной плоскости</kwd><kwd>скоростной пучок</kwd><kwd>компьютерное моделирование движений антропоморфных роботов</kwd><kwd>синтез движений манипуляторов</kwd><kwd>запретные зоны.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mechanisms of manipulators</kwd><kwd>instantaneous states of mechanisms</kwd><kwd>vector of generalized velocities</kwd><kwd>graphical constructions of the velocity plane</kwd><kwd>velocity beam</kwd><kwd>computer modeling of the movements of anthropomorphic robots</kwd><kwd>synthesis of manipulator movements</kwd><kwd>restricted areas.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zheng X., Han Y., Liang J.
