Australian researchers develop cockroach-based robots for rescue medicine delivery

Researchers from the University of Queensland and the University of New South Wales have developed “paraborgs,” bio-hybrid robots designed to deliver emergency medication to victims trapped under rubble. The technology utilizes the giant burrowing cockroach (Macropanesthia rhinoceros), a species native to northern Queensland capable of reaching 8.5 centimeters in length.

To control the insects, technicians equipped them with small backpacks containing cameras or injection devices and implanted electrodes into their nervous systems. This allows researchers to stimulate the insects with electrical signals to direct their movements. The natural ability of these cockroaches to navigate irregular terrain, climb walls, and move through narrow spaces makes them ideal for unstructured environments like collapsed buildings.

In initial tests, an “observer” cockroach equipped with a camera located targets, while a second cockroach with an injection mechanism was used to deliver medicine. The study reported a 100% success rate in reaching designated control points and a 72% success rate in medicine delivery. When the injection was triggered within 15 centimeters of the target, the success rate rose to 95%. While promising, the technology requires further study regarding communication stability and movement within complex debris before real-world rescue deployment.
