I seem to remember an episode where the crew was on a planet fighting against drone like weapons that learned behavior and were autonomous and out of human control. Am I remembering correctly or was this some other show?

I think maybe you are thinking of Star Trek: The Next Generation episode called "The Arsenal of Freedom".

Yep that sounds like the one. I was watching a program on tiny swarm drones that could coordinate their attack and thought of this show. Knew it was Star Trek just bas the wrong series. Thanks
