Today, robotics is one of the key areas of creating new smart technology. The peculiarity of such robotic devices is a wide variety of movements of their executive bodies, including the ability to construct so-called anthropomorphic movements that imitate to some extent the movements of a person and his limbs. One of the important qualities of any anthropomorphic device is the kinematic similarity of its working movements to similar human movements. However, the movements of most existing robots are formed according to traditional machine control schemes, which leads to the machine kinematics of these movements, which is sharply different from the living kinematics of a person, although the intended purpose of the movements is almost the same. Therefore, when developing anthropomorphic manipulators, it is extremely important to ensure not only the kinematic similarity of their movements to the movements of human arms and legs, but also to give them smoothness. The issue of creating a natural-looking human hand is of great relevance for modern science and technology. This is primarily dictated by the need to create universal manipulators for flexible production, solving the problem of prosthetics of the upper limbs and developing anthropomorphic robots to assist a person in various areas of his activity. The article discusses the possibilities of creating a robot manipulator in the form of a human upper limb, in the sense that the robot will be able to repeat the basic movements of the hand: shoulder, elbow and hand. Available low-cost means were used in the design, which helps to reduce the cost of the final product in order to make it accessible to all segments of society. The goal is achieved using 3D modeling and additive printing technology. The work of the hand gripper, that is, bending and unbending the fingers, is not considered in the work. As a result, we will receive a ready-to-use prototype of the hand for the operator, who will remotely move his hand “transfer” the movement to the robot manipulator.
