A7-series Labour Droid

First introduced in 1497 BBY, the A7-series were the most common heavy labor droid in the Confederacy until the introduction of the BS-series Labour Droid in 444 BBY, and remained in common service with cash-strapped companies even after 444 BBY. By 18 ABY the series had reached its 40th incarnation (A7-40).

A7 droids were simple-minded droids, strictly working droids and nothing more. Their vocabulary consisted of only "Yes/Affirmative" and "No/Negative".
