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 his face. He's cute, but asks tough questions.
