Should People or Robots Explore Space?

In science fiction, you could have robot bodies awaiting for you at your destination in space. And so why wouldn't we just go into orbit around a planet? You know, if it's like a planet with a surface gravity of two g, you're not getting back off that planet. Why even, unless you need to be a physical body, why would you be? Maybe we'll just put our mind into a robot that's made for space. N robots don't care about cosmic and that that's the solution.
