Israeli scientists plan to equip the robot with navigational capabilities, which will allow it to determine the source of the smell and its identity.
Dr. Ben Maoz of Tel Aviv University, Professor Amir Ayali and graduate student Neta Shvil have developed a new technology that allows a robot to sense with a biological sensor, according to a study published Tuesday in the journal Biosensor and Bioelectronics. The researchers connected the sensor to an electronic odor detection system with a sensitivity level 10,000 times higher than current electronic devices.
“The sensor sends out electrical signals in response to the presence of an odor nearby, which the robot can detect and interpret. The researchers believe that, given the success of their research, this technology could also be used to identify explosives and drugs in the future. or disease,” the university said in a press release.

Ben Maoz and Amir Ayali, who led the study, explained that smell perception is one area where technology is lagging behind. “At the airport, we go through a magnetometer that costs millions of dollars to determine if we have metal devices. But when it comes to checking if a passenger is carrying drugs, we bring a dog to smell it,” they noted. adding that the mosquito is able to detect “a difference of 0.01% in the level of carbon dioxide in the air.”
The researchers also noted that some animals can sense illness, while others can even sense earthquakes. In their future work, the Israeli scientists plan to equip the robot with a navigational function that will allow it to locate the source of the smell and its identity.
