Probably due to how they can't really go fast

There are many droids in Star Wars. Some of the ones not meant for battle are protocal droids (C-3PO), Astromich droids (R2-D2), Gonk droids, ect. Some meant for battle during the clone wars are battle droids, super battle droids, destroyer droids (also calles droidekas), and General Greivous' body guards. General Grievous is not considered a robot, for he was once an alien, until betrayed by Count Dooku. He was in a star cruiser when it exploded. In order to survive, he needed to wear robotic pieces. actually general grevious is a cyborg part human part robot because he got injured :)
No, but many Star Wars droids exhibit characteristics that modern robots and computers do already have.
In star wars robots are "droids" and there are many kinds including soldier ones. This vary from battle droids and super battle droids (robots with guns) to robots who can dismantle enemy ships and jam radio waves. other droids do work such as medical droids, atsromec droids(R2D2) who control small ships and interpertor droids who can memorize thousands of languages.
Yes, many different kinds--from R2 units and protocol units to various mechanical and administrative droids as well as reconnaissance and military droids.
Not all the droids in Star Wars talk. Some make noises, like R2-D2. Those who can speak are rather limited to protocol droids and others like Trade Federation battle droids; the battle droids have a limited vocabulary even then. Others, like pit droids, make weird noises...
