Just what you want crawling through the rubble to rescue you: A swarm of remote-controlled cockroaches with syringe-shooting guns strapped to their backs
Picture this: You’ve just undergone one of the most harrowing experiences of your life, and you’re trapped in the rubble of a collapsed building. You’re injured, air is running out, and human rescuers can’t reach you. But crawling through the rubble to administer life-saving drugs and reassure you comes the last thing you’d expect: a swarm of cyborg cockroaches bearing tiny syringes.
Unfortunately for those who’d rather find solace in the arms of a fluffy, drooly St. Bernard, this tale is anything but science fiction. It’s not even a new idea: Cockroaches fitted with electronics that allow rescue workers to control their movements from a distance have been on the research docket for biotech researchers for some time. What’s new in this latest experiment from researchers at Australia’s University of Queensland is outfitting the, erm, little buggers with devices remote rescuers can use to shoot a drug dart into trapped patients.
“A lot of people might not like the sight of a giant cockroach scurrying towards them, but if you’re trapped in rubble or stuck in a cave and need help, it could make a real difference between life and death,” PhD candidate and lead research paper author Hai Nhan Le told the University of his phobia-triggering project.
Giant is right – the species chosen for the project, the giant burrowing cockroach, is the world’s heaviest roach species, and can grow up to 8 centimeters in length, or around 3.1 inches. Known to be docile, they’re popular pets in their native Australia, and – lucky for anyone coming face to face with one while trapped in a pile of rubble – they’re known to be relatively clean and disease-free, too.
The giant burrowing cockroach was chosen for its size, per the paper, as they needed to be large enough to “integrate centimetre-scale apparatuses for … real world scenarios.”
The “paraborgs,” as the team calls their subjects, were outfitted with electrodes that gave researchers the ability to make the roaches turn left and right, control their speed, and immobilize them in order to deliver drugs without the roach moving while scientists tried to take aim. Then they were fitted with various add-ons specific to their roles in the paramedic swarm –one built to search, another equipped with a single launchable drug syringe, for example.
Outfitting the roaches with their cyborg backpacks isn’t fatal, and the team said that their subjects were able to live just as long as other roaches once their harnesses were removed.
*shudder* Well, at least they're good at their jobs
The Queensland team had overwhelming success in getting their paraborgs to end up where they wanted them - 100 percent successful, in fact, the paper said.
As for drug injection, the auto-injection mechanism succeeded 90 percent of the time, and paraborgs able to get within 15 cm of a target (5.9 inches) were able to successfully inject drugs 95 percent of the time.
The only trouble spot for the experiment was getting the robo roaches to sit still, with only a 72 percent success rate in stabilizing the cockroaches for injection targeting. That’s still a pretty good rate of success, leaving the team to predict that swarms of specially-outfitted paraborgs could be swarming over disaster sites in a matter of a few short years.
“Some could carry cameras and environmental sensors, while others could carry specialised emergency or medical equipment,” UQ robotics engineering lab director and lecturer Dr. Thang Vo-Doan said of the project. “Hopefully, within the next 5 to 10 years, we could see cyborg insect rescue teams deployed to help people in real emergencies.”
Hopefully large bugs bearing medical aid isn’t something that’ll send you into a panic. ®
