MIT Scientist’s Quest For a Bot That Can Smell As Well As a Dog

“We have $100 million worth of equipment downstairs. And the dog can beat me?” MIT scientist Andreas Mershin asks. “That is pissing me off.” Mershin aims to develop a bot that detects an antigen that can be an indicator of prostate cancer. It’s one that properly trained dogs can sniff out with 90% accuracy. The physicist’s lab, Label Free Research Group, is attempting artificial olfaction, and while “robots these days can see, hear, speak, and (crudely) think,” scent is harder to pinpoint.
