Designer Creates Prototype for Robot Armpit That Smells Like Real Armpit

Look closely. What you’re seeing isn’t chewing gum that’s been left on the floor of a hair salon. That’s a robot armpit prototype, built by designer Kevin Grennan as part of his studies on the role of smell in human-robot interaction. He’s also developed ideas for adding scent glands to industrial robots — like a surgical robot that releases the trust-building hormone oxytocin.
