But others see some different tasks for these humanoids. Former astronaut Steve Hawley, a professor of astronomy at the University of Kansas and a veteran of five Space Shuttle flights, including two Hubble Space Telescope missions, envisions robots taking over some tasks that are just too dangerous for humans.
"There are places on the space station no camera can see -- if you send a robot out to circle around the space station and transmit video, that would give you quick answers to how it's operating -- and be able to check for damage," Hawley told ABC News.

Humans and robots make a good team in space, Hawley said. "If we go to Mars, you could send the robot out for long distances to bring samples back to an astronaut at a habitat."
Of course, robots are already racking up spectacular successes on Mars. The Mars Curiosity rover is one year into its mission, and the rover Opportunity is still trucking after eight years.
That is the key, according to Ambrose: You can launch a robot, send it outside, and it doesn't need food, or water or a return ticket.
"Those robots on Mars are not going to come home the easy way, and they get one-way tickets. The robots on Mars are probably there forever. But that's okay for a robot," Ambrose said.
That's why Ambrose anticipates robots could work as an advance team for an eventual human mission to Mars. "We could deploy the habitat years in advance with a robot to putter around and set things up to be ready for a human crew," Ambrose said.
But these robots aren't just robots. NASA has been working hard to give them personalities. Remember HAL in the movie "2001: A Space Odyssey"?
"Dave: Open the pod bay doors, HAL. HAL: I'm sorry, Dave. I'm afraid I can't do that. Dave: What's the problem? HAL: I think you know what the problem is just as well as I do."
But, real-life robots are much less threatening. Robonaut and Kirobo give off a much more relaxed vibe, at least on Twitter. These two robots are so friendly you could imagine C3PO playing Robonaut in the movies, and R2D2 could almost pass for Kirobo.
Kirobo is the first space robot that can talk and react to an astronaut -- his voice and face-recognition software are top secret -- so confidential that when we asked Japanese Astronaut Koichi Wakata about him, Wakata demurred, on the grounds that it was propriety information. Kirobo is probably the cutest robot to go to space, which is good, since his job is be Wakata' s companion on the space station when he takes over command.

Robonaut is more the strong silent type. He isn't chatty, but his tweets show a sense of humor -- telling Mars Curiosity he wasn't into long-distance relationships and mentioning he would take up the guitar since there were no pianos on the space station.
Ambrose said he hopes robots of the future won't be a smarty pants like Star Trek's Commander Data. "The first science fiction movie I really remember was 'Silent Running,'" he said. "It was about a set of robots that helped tend gardens in space and they had a little personality -- Huey and Dewey."
