The article is devoted to the review and analysis of various approaches to determining the movement of the operator’s hands in order to formulate control laws for an anthropomorphic gripping device in copy mode. Authors performed a review of various to determine the movements of the phalanges of the operator’s fingers; these methods use bend sensors, a localization system for sound sources, microelectromechanical systems (MEMS sensors), rotation angle sensors, or a computer vision system. An analysis of each method is carried out, their advantages and disadvantages are revealed. The principles of operation of the master devices based on the considered methods are described. The choice is justified of methods that will be used to develop an anthropomorphic gripper operating in copy mode.
