very large void spaces within them that have potential for survivors
Micro drones equipped with thermal cameras and night-vision can navigate through small cracks and rubble spaces to detect heat signatures and locate trapped survivors in high-rise apartment buildings. International rescue teams are combining drone technology with specialized listening equipment, search dogs, and human expertise to search for tens of thousands of missing people across a dense urban disaster zone.

A week after devastating twin earthquakes in Venezuela killed over 2,200 people, rescue teams are deploying micro drones and experimental cyborg insects to locate survivors in collapsed buildings, with technology enabling access to spaces unreachable by humans.
Seven days after two massive earthquakes tore through Venezuela, the work of finding survivors had become a race against time measured in hours. A toddler pulled alive from six days of darkness under collapsed concrete brought cheers from rescue workers in La Guaira, but such moments were growing scarce. The twin shocks—measuring 7.2 and 7.5 in magnitude—had killed more than 2,200 people and left tens of thousands unaccounted for, making it one of Latin America's deadliest earthquake disasters. The destruction was concentrated in a dense urban landscape of high-rise residential towers, their reinforced concrete frames now reduced to rubble that created what rescue coordinators called "very large void spaces"—pockets where people might still be alive.
International rescue teams had descended on the country with dogs, listening equipment, cameras, and something newer: fleets of specialized drones small enough to slip through cracks in the wreckage. John Morrison, leading a team from Fairfax County in Virginia, explained the search methodology to Australian radio from the disaster zone. Rescuers would first talk to locals, asking when they last heard sounds from inside a building. Then came the listening—technicians with specialized equipment straining to detect any noise from within the structure. Search dogs would work the rubble piles. And increasingly, the drones would go where humans could not.
The United Nations' humanitarian chief Tom Fletcher had singled out what he called "cockroach drones"—micro-sized aircraft equipped with thermal cameras and night-vision capability—as crucial to the operation. These machines, often about twenty centimeters long with a quad-copter design, could navigate through confined spaces and detect the heat signatures of human bodies. A Mexican rescue organization called Topos Azteca posted video footage showing one of these drones' night-vision feed as it penetrated a damaged building, its camera sweeping across rooms in search of any sign of life. The technology did not replace human rescuers, the group emphasized, but it allowed teams to gather critical information while keeping their members out of immediate danger.
Nabin Sharma, an associate professor at the University of Technology Sydney, explained the advantage in simple terms: a micro drone could be maneuvered through a small hole and into spaces where even larger robots would struggle. The sensors aboard these machines could process vast amounts of data quickly—thermal imaging, acoustic detection, video feeds. Researchers were even developing technology to filter out the noise of the drone's own propellers so that operators could hear faint human voices or cries for help emanating from beneath the rubble. Similar drones had been deployed after Turkey's 2023 earthquake, where they not only located survivors but delivered supplies to people still trapped.
But the frontier of rescue technology extended beyond conventional drones. The term "cockroach drone" might have been Fletcher's colorful way of describing the agility of micro drones in general, but it also hinted at something stranger: actual cyborg insects. In March of the previous year, Singapore's Home Team Science and Technology Agency had partnered with Nanyang Technological University to deploy ten microchip-controlled cockroaches in Myanmar after a 7.7-magnitude earthquake. The insects, fitted with devices that sent signals to their nervous systems, could be guided through rubble spaces that conventional robots could not access. They found no survivors in that operation, but researchers saw the potential. The team was now working to scale up production for future disasters.
Thang Vo-Doan, a lecturer at the University of Queensland, was also developing cyborg insects for disaster response. The technology worked by attaching devices to a cockroach's nervous system, allowing operators to control its movement—directing it left or right, speeding it up or slowing it down. The insects could carry cameras that streamed video back to controllers, and environmental sensors that measured temperature and humidity. If a human body was detected at a temperature indicating life, rescue teams would know. Vo-Doan said the technology was still being refined but could be ready for deployment in a real disaster scenario by early 2027. For now, in Venezuela, the work continued with the tools at hand: drones, dogs, listening equipment, and the determination of rescue workers who said they would keep searching as long as there was any possibility someone remained alive in the wreckage.

Why does size matter so much with these rescue drones? Why not just use the larger ones?
A large drone can't fit through a crack in a collapsed building. These micro drones are small enough to slip through spaces where a human rescuer would get stuck, or where a bigger machine simply won't fit. They're going into rooms, stairwells, underground voids—places that are inaccessible otherwise.
And the thermal cameras—they're looking for body heat?
Exactly. A person trapped under rubble still radiates heat. The drone's thermal sensor can detect that signature and show it on a screen back at the operator's station. Combined with night vision, the drone can work in complete darkness inside a collapsed building.
This cockroach drone thing sounds like science fiction. Are they actually using real insects?
Not in Venezuela, not yet. The term might just be a nickname for how agile the micro drones are. But yes, cyborg insects are real—they've been tested. Singapore deployed ten microchip-controlled cockroaches in Myanmar last year. The insects can navigate spaces even smaller than drones can reach.
How do you control an insect?
You attach a microchip device to its back that sends signals to its nervous system. The operator can make it move in different directions, speed up, slow down. It can carry a camera and sensors. It's still experimental, but researchers think it could be ready for real disaster response next year.
What's the success rate? Are they actually finding people?
In Venezuela, yes—a toddler was pulled out alive after six days. But as time passes, the chances get smaller. The drones and insects are tools to speed up the search, to reach places humans can't. They're not magic. They're just giving rescue teams better information faster.
What happens after the technology finds someone?
That's when the human rescue workers take over. The drone or insect locates the person, confirms they're alive, and then the team has to do the hard physical work of extracting them from the rubble. The technology is the eyes and ears. The rescue is still human work.
