Scientists from Israel have developed a sniffing robot which is equipped with a biological sensor. The robot uses the antennae of a locust to diagnose disease and improve security checks.

• Locusts smell with their antennae. The scientists will use the locust's antennae to hone the computer's scent detection abilities.
• Researchers at Tel Aviv University have managed to harness their bio-hybrid robot, making it far more sensitive than existing electronic sniffers.
• The scientists have placed the insect's antenna between two electrodes that can send signals to identify the odour on a four-wheeled robot. The robot can identify different types of scents with machine learning.
