Use Micro Servos :


Try get the same servos from somewhere else because these are overpriced.

You can even use small geared DC Motors :


These really fast for arm but can always control the speed.

Start ordering online , you will see its less of a headache and cheaper if you know the right sources.

Microservos are pretty cheap on a lot of Chinese sites deal extreme for ex.
