As we all learned from Terminator, artificially intelligent machines will one day conduct a systematic extermination of all human life forms and turn the Earth into one gigantic robot playground. But until that day comes, robots are our friends. From heavy industry to the toy industry, devices that perform at least some automatic functions have been with us for quite some time. But in this roundup, we'll look at robots that go far beyond the basics. Some benefit humanity as a whole. Some are already at work in the corporate world, handling complex or tedious tasks and situations that even a decade ago seemed impossible. Some point the way to a better future, others impress with their ability to mimic life forms, and still others make us feel a bit apprehensive as we come to grips with their tremendous power and potential. No, there's not a Terminator or Rosie the Robot in the bunch, though there is one that costs more than the annual economic output of some countries and is designed to function for a mere two years. And that alone is almost as frightening as the former. Or perhaps as ridiculous as the latter, depending on your perspective.
