I vaguely recall MIGHTY ORBOTS, and of course GO-BOTS, but TRANSFORMERS was pretty much the king of robot shows.
True story; "BLACKSTARR" was actually supposed to star an African American hero as the "lost astronaut turned barbarian", but that was considered too "racy", pun intended, for the early 80's CBS network people, so the character was changed to a white dude as production started. BRAVESTARR, which aired a few years later, was among the first major shows of the 80's to star a non-white lead who was clearly Native American (the hero in BLACKSTARR was hinted at being Native American, but it was never revealed).
