Robots can be scary. Dystopian films such as The Terminator tell the story of a world where robots take over.

But for some, robots are more like R2-D2, the cute bot from Star Wars. At this year's South by Southwest interactive festival, a petting zoo is aiming to evoke those same feelings. But, not just any petting zoo: a robot one.

BlabDroid is a small robot, less than a foot high, with bulldozer wheels, a cardboard body and a smile on its face. He's cute, but asks tough questions.

"Tell me something that you've never told a stranger before," he says.

NPR may not be the best platform to reveal secrets, but privately, the robot might have gotten an answer. Alexander Reben, BlabDroid's maker, says that's what he was designed for. Reben was studying robot human interaction at MIT when they decided to put a camera on the robot to see how people would respond with no one else was around.

Made of cardboard, BlabDroid asks tough, personal questions that many people are apparently willing to answer.

"It asked a guy from the Boston Marathon who wondered into the lab randomly, 'What do you do here?' " Reben says. "And he laid down on the floor and started saying 'Man, you know my flight has been grounded, and I really want to go home.' There's something here if this guy goes and tells a robot something that he wouldn't tell a person that he just met in that area."

BlabDroid actually has some pretty sophisticated wiring inside, but with its cardboard shell with a smile cut into it, he looks like he was made in someone's garage. Reben says that's intentional.

"In a relationship with a robot, where you're being very vulnerable, the other actor in that situation has to be as vulnerable as you," he says. "So if the robot is small, tiny, made out of cardboard, you kind of feel like you can open up to him more because he's very familiar and you feel like you're in control of that situation."

Recently, Reben linked up with a nonprofit organization that assembles volunteers in the tech industry to be available when a disaster hits. The goal is to deploy BlabDroid to communicate with survivors.

"When you just got through a difficult situation where you may not want to talk to other people about what's happening, like if you have a fun character come in, it's not as serious as coming to a psychologist," Reben says.
