Israel launches sniffing robots
The Locusts have very good smelling power. Israeli researchers have used the antennae of the locusts to create sniffing robots. The bot is bio-hybrid and therefore its sniffing powers are higher than the electronic sniffers. With Machine learning, the bot has been taught to identify different smells.
How was the robot created?
The robot has four wheels. It was created by placing the antenna of locusts between the electrodes. The electrodes send signals when the antenna grabs a nearby scent. Each scent has a unique measurement of current. Based on the current generated, the bot identifies the scent. The bot is calibrated previously for the scent it grabs and the corresponding current value.
Applications
With this, Israel has taken investigative technologies to next level. The bot sniffers can be used to detect drugs and explosives.
About the robot
The bot can detect even the tiniest particle or an organism in its surrounding. For instance, it can even detect a mosquito!
Scientific Principle used
Every sensory organ of animals or insects generates an electric signal when they encounter external stimuli or a smell. These electric signals are sent to their brain to be processed and identified. The robot uses the same principle.
