A kinematic model of the mechanism was constructed, and the law of motion was determined in the form of an analogue of the speed and position function of the output link. An experimental setup of the proposed planetary transmission has been developed, on the basis of which the position functions for three variants of the mechanism with different kinematic parameters have been investigated.
