Need title of old campy space movie

[anonymousone]

I saw this movie about 20 years ago and I would guess it was made in the 70s.

Here are the details that I remember.  Explorers or scientists travel far away by space ship to a distant planet.  On the dark planet, a ruler that looks like a robot has enslaved the blue skinned population.  I remember the robot standing over a hill, overseeing the poor aliens who are digging.  The human adventurers mix it up with the overlord and eventually escape with one of the blue skinned aliens, who joins the crew wearing their uniform.  Then something happens on their way back (they're attacked or possessed, not sure) and the alien sacrifices himself to the save the crew and the last thing we see is the sinister looking robot.

Any help would be appreciated.

Thanks

Hmm..... "War of the Planets" perhaps? Here's a review of it with pictures and a movie clip : http://www.bmoviecentral.com/bmoviecentral/reviews/War%20of%20the%20Planets.html

Yes!  Thank you, Jordan.  This is exactly the movie I'm talking about!  Looking at the pictures, I'm surprised the robot actually scared me as a kid.
