May the 4th be with you! And there are lots of cool robots in the Star Wars scifi universe. What's the real world science behind them?

Who knew Val Kilmer starred in a scifi movie with a robot on Mars? No one knows… because Red Planet was a big budget flop. But the AMEE robot anticipated Perseverance and Ingenuity by 10 years!

A real robot: NASA JPL Hazbot III was first through the Stargate in 1993 movie that started the franchise. Real robots go first!
