Robotic Ferret Sniffs Out Drugs, Weapons and Illegal Immigrants

Posted by Alex in Science & Tech, Weapons & War on June 14, 2009 at 1:36 pm

Coming soon to a seaport near you: a robot dubbed the "cargo-screening ferret" that will detect drugs, weapons, explosives and even illegal immigrants hidden in cargo containers.

Recent advances in both laser and fibre optic technology now make it possible to detect tiny particles of different substances. The EPSRC-funded project team is developing sensors which incorporate these technologies and that are small enough to be carried on the 30cm-long robot, in order to detect the specific ‘fingerprint’ of illegal substances at much lower concentrations than is now possible.

When placed inside a steel freight container, the ferret will attach itself magnetically to the top, then automatically move around and seek out contraband, sending a steady stream of information back to its controller.
