Servos are mounter between different parts of limbs (where humans have their joints)  ;)

It is not possible to know kind of drive and gearing ratio just by looking at the robot. You have to get datasheet to find out.

I suspect that they are driven by brushless motors in a similar way PC fans are driven.
