Samsung's smart robot can answer questions and be a security guard

Creativity is alive and well at Samsung, which is developing several cool devices in its labs, including a home companion robot called Otto. The multi-talented robot can answer questions and double as a part-time security system when needed. It is expected to be demonstrated at the Samsung Developer Conference this week in San Francisco. Functionally, Otto is similar in some ways to Amazon Echo, featuring an interactive speaker that can answer questions, order products and play music. But the robot also includes a "head" that hosts a high-definition camera and a display.
