From the patch notes: Repair Bot

[Daymare]

vub me and give me all your gold!
-----------------------------------------------------------------------
A new engineering recipe is available in Blackrock Depths for a repair robot. This robot acts as a repair vendor for 10 minutes and will repair and purchase items for normal cost. This will allow dungeon groups and raids to get items repaired and sold without returning to town.

Nice feature, i guess its really needed :P

[Visionaire]

well the repair bit is nice, but the sell bit is rather silly. Where does the robot get the money from? :p

[Shinigami]

Maybe you can pickpocket it and steal all its cash? :)

[Nyana]

WOOT!

I see possibilities there :D (@shini)
