The work is devoted to the urgent task of studying the features of functioning and assessing the effectiveness of using an industrial exoskeleton for the tasks of lifting, holding and storing cargo. A feature of the study is the use of an original method based on the interpolation of experimentally obtained data and their use in mathematical modeling of the behavior of the system. The proposed method and evaluation criteria make it possible to determine the operator's labor costs and the efficiency of using an exoskeleton, including those equipped with gravitational compensators in the hip joint. In this work, the time dependences of the torques in the hinges of the exoskeleton for various methods of performing the exercise and various parameters of assisting influences were obtained. The proposed toolkit can find application in the design and assessment of the effectiveness of exoskeletons of industrial anthropomorphic structures.
