New Scientist reports on a project by Georgia Tech researchers Ja-Young Sung and Rebecca Grinter that examines how people interact with Roomba:
"Dressing up Roomba happens in many ways," Sung says. People also often gave their robots a name and gender, according to the survey (see Diagram) which Sung presented at the Human-Robot Interaction conference earlier this month in Amsterdam, the Netherlands.
Kathy Morgan, an engineer based in Atlanta, said that her robot wore a sticker saying "Our Baby", indicating that she viewed it almost as part of the family. "We just love it. It frees up our lives from so much cleaning drudgery," she says.
Sung believes that the notion of humans relating to their robots almost as if they were family members or friends is more than just a curiosity. "People want their Roomba to look unique because it has evolved into something that's much more than a gadget," she says. Understanding these responses could be the key to figuring out the sort of relationships people are willing to have with robots.
Until now, robots have been designed for what the robotics industry dubs "dull, dirty and dangerous" jobs, like welding cars, defusing bombs or mowing lawns. Even the name robot comes from robota, the Czech word for drudgery. But Sung's observations suggest that we have moved on. "I have not seen a single family who treats Roomba like a machine if they clothe it," she says. "With skins or costumes on, people tend to treat Roomba with more respect."
So as they move from environments that we don't like into places that are more familiar, and from doing work we hate to work we just dislike, two things happen to our perception of robots: their social status goes up, and they become more familiar. But this doesn't just happen with robots who are doing "dull, dirty and dangerous" jobs: humans who are doing those jobs can develop bonds with those robots, too.
US soldiers serving in Iraq and interviewed last year by The Washington Post developed strong emotional attachments to Packbots and Talon robots, which dispose of bombs and locate landmines, and admitted feeling deep sadness when their robots were destroyed in explosions. Some ensured the robots were reconstructed from spare parts when they were damaged and even took them fishing, using the robot arm's gripper to hold their rod.
Figuring out just how far humans are willing to go in shifting the boundaries towards accepting robots as partners rather than mere machines will help designers decide what tasks and functions are appropriate for robots. Meanwhile, working out whether it's the robot or the person who determines the boundary shift might mean designers can deliberately create robots that elicit more feeling from humans. "Engineers will need to identify the positive robot design factors that yield good emotions and not bad ones - and try to design robots that promote them," says Sung.
