Ana iya amfani da Servos don samar da motsi na layi ko madauwari, ya danganta da nau'in su. Kayan kayan shafa na servo na yau da kullun sun haɗa da motar DC, jirgin ƙasa na gear, potentiometer, haɗaɗɗiyar da'ira (IC) da mashin fitarwa. Matsayin servo da ake so shine shigarwa kuma yana zuwa azaman siginar lamba zuwa IC. IC yana jagorantar motar don tafiya, yana motsa makamashin motar ta hanyar gears wanda ke saita saurin da ake so na motsi har sai sigina daga potentiometer yana ba da amsa cewa an kai matsayin sha'awar kuma IC ta dakatar da motar.

Potentiometer yana sa motsi mai sarrafawa ya yiwu ta hanyar sake mayar da matsayi na yanzu yayin da yake ba da izinin gyare-gyare daga dakarun waje da ke aiki a kan matakan sarrafawa: Da zarar an motsa saman mai karfi yana ba da siginar matsayi kuma IC yana nuna alamar motsin motar da ya dace har sai an dawo da matsayi daidai.
Haɗin haɗin servos da injunan lantarki da yawa za a iya shirya tare don yin ƙarin ayyuka masu rikitarwa a cikin nau'ikan tsarin daban-daban da suka haɗa da mutummutumi, motoci, masana'anta da firikwensin mara waya da cibiyar sadarwa mai kunnawa.
