Security Robots

"Meet The Scary Little Security Robot That's Patrolling Silicon Valley":

Looking like a sleeker, taller version of R2-D2 or a Dalek, depending on which sci-fi reference point you're coming from, the K5 comes with a series of sensors and cameras and is designed for perimeter patrolling. It acts as a mobile camera for its operators as well as a detection device in its own right. Its "audio event detection" system senses for things like cars honking, glass breaking, and people screaming. It can scan license plates, separating out cars that are allowed somewhere and those that aren't.

"They're meant for a support role, observing and reporting only," [marketing executive Stacy] Stephens assures us. "There's no offensive measure to them at all."

For now anyway.
