Researchers in Australia have transformed cockroaches into cyborg systems to reach people trapped under rubble after natural disasters and provide initial medical aid. In the project jointly conducted by the University of Queensland and the University of New South Wales (UNSW), the animals’ mobility was combined with lightweight electronic equipment.
Precision Injection System
The study used North Queensland giant burrowing cockroaches measuring approximately 84-87 millimeters in length and weighing 34-40 grams. Electrodes, microchips and miniature injection mechanisms were placed inside the bodies of the anesthetized insects. The cockroaches were reported to have continued living without any harm after the procedure. The study aimed to advance previous research into developing cyborg cockroaches for saving lives in disaster zones and to enable first-aid medications to be delivered directly.
Success Achieved in Trials
In laboratory tests, the cyborg cockroaches achieved a success rate of 95% in moving toward the designated target and carrying out injections from close range.
When the stages of steering, alignment and drug injection were evaluated together, the overall success rate was measured at 72%.
Bio-robotics engineer Dr. Thang Vo-Doan said that, with the support provided by biomechanical structures, critical emergency aid could be delivered on time to casualties located in narrow, rubble-covered areas where direct access is not possible.
Field Use and Future Goals
According to the project team, reaching the target and maintaining stability during injection are among the most challenging engineering problems encountered. These living organisms, which can access spaces too narrow for humans to enter, are expected to expand the areas that search-and-rescue teams can reach. The technology is intended to be used within the next 5 to 10 years at real disaster sites in the form of cyborg swarms performing different functions.
