WATCH: Robot dog can sense bad odor, alerts people to change their socks

Posted: Updated:

A company in Japan has created a robot that looks like a fuzzy toy dog, and it's meant to detect bad odors.

The robot can "tell" you when you need to change your socks.

If the robot dog senses a bad odor, she literally falls over.

It took five years to develop a robot that can tell the difference between pleasant smells, and stinky socks.

The robot costs $300.
