OK... not robots, but collectables from my world. Haven't really spent any money on this in a long while... think I got married or something, so I'm missing some of the awesome sets that went through. But yeah, Original Series Lego:
Y-wing from tunnel run and X-wing from Dagoba (with wife beater Luke)
The Tie Bomber, Tie Fighter and Vader's Tie Fighter.
Other randoms - Yoda's hut, various Endor sets including the Wookie AT-ST
Someone gave me Anakin's pod racer, but its dead to me. Stupid prequels.
