Robotic Bloodhound Tracks Scents Along the Ground

Jun-23-18 A robotic bloodhound invention can track scents along the ground quickly, and could even use scents to communicate with other robots.

While scent-tracking robots are not new, the prototype device from the team at Kyushu University is able to detect and track scents at up to 3.9 inches per second. The robot is equipped with treads that allow it to travel along the ground, while a tube on the bottom draws the odor molecules from the ground to the bot’s localized surface plasmon resonance (LSPR) sensor. By measuring light changes in response to exposure to gas (currently ethanol), the robot can detect the scent along the ground, or even draw readable binary barcodes in scent for other robots to read.
