Currently, to my knowledge and to the knowledge of everyone I've spoken with so far, there is nothing in-game for Rigging. All current use of the skill is through the aid of a staff member.
The skill isn't implemented completely for a reason, I'm sure. It encompasses quite a bit mechanically and balancing-wise. Still, I'd like to see if it something could be added in baby steps to make the ability mechanically useful. We don't need hover drones with dual auto-guns or anything, but the ability to remotely control cameras or a drone with two-way audio/video (think Korova feed for example) would be simple enough, and would use code that I assume already exists in the game.
