Droid question

[Kuja]

On the main site, there is this passage from the novel "Lightsabers" used to demonstrate the strength of stormie armor:

"Qorl stood inside the training chamber holding a wicked-looking spear in his black-wrapped left hand. His droid replacement gripped the gleaming shaft with enough force to dent the metal."
...
"He cocked his droid arm back - and hurled the deadly weapon ..."
"Norys slammed into the wall, his helmet ringing against the hard metal bulkhead. His vision sparkled with impending unconsciousness."
...
"He looked down at his chest in amazement and saw only a nick in the white armor where the spear had struck."

I'm just wondering: what type of droid is this? Does the book ever say?

Ask Poe. He has something about this on his site somewhere.
