Odnim iz strategicheskikh napravleniy razvitiya pnevmatiki yavlyayutsya proportsional'nye privody. Razvitie etogo napravleniya obuslovleno vozniknoveniem novykh prilozheniy proportsional'nogo pnevmoprivoda. Proportsional'naya pnevmatika trebuet razrabotki ispolnitel'nogo elementa, sposobnogo kompensirovat' szhimaemost' szhatogo vozdukha, obespechivat' vysokuyu tochnost' pozitsionirovaniya i znachitel'nuyu moshchnost'. Takie ustroystva poluchili nazvanie mekhanicheskikh myshts, poskol'ku sozdavalis', kak tekhnicheskie analogi skeletnykh myshts zhivogo sushchestva. Upravlyaemoe dvizhenie zhivykh sushchestv vo vneshney srede obespechivaet biologicheskiy privod, vklyuchayushchiy v sebya skeletnye myshtsy, sistemy sbora, peredachi i obrabotki sensornoy informatsii, formirovaniya struktury upravlyayushchego signala. Sozdanie tekhnicheskogo analoga stol' slozhnoy biologicheskoy sistemy nevozmozhno bez detal'nogo izucheniya protsessov, proiskhodyashchikh v skeletnykh myshtsakh. Vypolneno issledovanie mekhanizma sokrashcheniya skeletnykh myshts zhivogo sushchestva. Vyyavlen fizicheskiy printsip preobrazovaniya energii. Sozdan tekhnicheskiy analog skeletnoy myshtsy.
