Friendly robots, the ones people love to love, are quirky: R2-D2, C-3PO, WALL-E, BB-8, Marvin, Roz and Baymax. They're emotional, prone to panic or bossy, empathetic and able to communicate like humans do—even when they communicate in only beeps and bloops. At Purdue University, Sooyeon Jeong, robot communication and behavior expert, is working to make robots as friendly and helpful as possible in nonfictional settings.
