The 1993 movie that started the franchise is well worth watching and has a real robot! When James Spader, playing a nice, sincere guy for once, helps the government use the stargate to open a wormhole, the first one through the wormhole is a robot. And not just a FX hack, it’s NASA Jet Propulsion Laboratory’s Hazbot III, brought out of mothballs for the movie. Hazbot sends back telemetry to indicate that the planet Abydos is earth-like and thus Kurt Russell and his special operations teams can safely make the next trip. Of course, the robot is never used again, either to help map out the alien planet or carry gear or to overcome Ra, the most beautifully androgynous alien since David Bowie in The Man Who Fell to Earth, but it was there first.
