Now here is a provocative thought, will robots one day have feelings? Will they know how to give back what many of us already do unconsciously? Not too long ago two students from Georgia Institute of Technology conducted a study on the relationship between Roomba/Scooba and their owners called "My Roomba is Rambo: Intimate Home Appliances". What they discovered was that Roomba owners do form an emotional attachment to their robots. Many owners treated their Roomba as a life-like object by giving them names, talking to them, petting them and feeling guilty for making them work too much.
But the issue will be if Robots, one day, develop "feelings" in order to provide us with emotional feedback. Will providing feelings to robots result on better and/or more efficient machines? Will it be necessary for human interaction? What will the implications be? These questions may seem too much like something out of a SciFi movie but they are important for future robot development since we are interacting with them much more in our daily lives (in our homes, battlefield, scientific research, exploration, human medicine/care and entertainment). So do not be surprised if one day your home robot will get angry at you because you forgot to pay the electric bill.
