Humans have long had a love/hate relationship with robots. For every lovable robot, like R2-D2 of Star Wars fame, or the robot in the campy 1960s TV series Lost in Space (Danger, Will Robinson!), there have been evil robots and humanoids we’ve feared, liked the replicants in the classic 1982 film Blade Runner. Then there’s the Terminator series, where Arnold Schwarzenegger’s “character” went from feared in the first movie to beloved in the sequels. But as we watched these movies and shows, very few people probably thought such advances in robotics would occur in their lifetime. Well, we were wrong. One day, in the not-too-distant future, human-like androids will likely walk among us undetected, acting like humans. Watching the following videos, you can see that technology in this field has come much further than you imagined.
