Yiziphi izivivinyo ezibalulekile ekukhiqizweni kwesilawuli se-servo?

Ukuhlolwa kungafaka phakathi ukuvulwa kwamandla, uhlelo lwe-firmware, ukuqinisekiswa kwesixhumi esibonakalayo se-encoder, ukulinganiswa kwemizwa yamanje, ukuhlolwa kwesigaba, uhlelo lobunikazi benethiwekhi, ukuhlolwa kokuxhumana, ukusampula kokushisa, kanye nokuhlolwa kokusebenza komthwalo wemoto.
