(American Chemical Society) Bloodhounds are famous for their ability to track scents over great distances. Now researchers have developed a modern-day bloodhound -- a robot that can rapidly detect odors from sources on the ground, such as footprints. The robot, reported in ACS Sensors, could even read a message written on the ground using odors as a barcode.
