A German company, SWARM Biotactics, is developing a new category of robotics: living, intelligent systems based on insects – equipped with custom-designed backpacks for control, sensing, and secure communication. These modular bio-robotic swarms augment the natural mobility of real organisms with AI, advanced sensors, and swarm intelligence – enabling silent access, close-range ISR, and real-time data collection where no other system can reach in cluttered, denied, and high-risk terrain.

 

The emerging use of insects for surveillance represents a convergence of biology, microelectronics, and sensing technologies, often referred to as bio-hybrid or cyborg insect systems. Researchers have demonstrated the ability to equip insects such as beetles, cockroaches, and moths with ultra-light sensors, cameras, and wireless transmitters that leverage the insects’ natural mobility, endurance, and ability to navigate complex environments. Unlike traditional drones, insects can move inconspicuously through rubble, dense vegetation, or indoor spaces, making them particularly valuable for applications where stealth, access, and persistence are critical.

 

A key advantage of insect-based platforms is their ability to access spaces that are physically unreachable or unsafe for humans and working animals such as dogs. Insects can pass through hairline cracks, collapsed structures, ventilation systems, and confined voids created by earthquakes, explosions, or industrial accidents—areas where human rescuers risk injury and dogs may be unable to enter due to size, heat, toxicity, or lack of oxygen. This capability enables early situational awareness, such as locating survivors, identifying structural hazards, or detecting chemical threats, before committing human or canine teams, thereby improving safety and response effectiveness.

 

From a systems perspective, insects offer a complementary capability rather than a replacement for humans or trained animals. Their small size and expendability allow for distributed sensing across complex environments, providing granular data from locations that larger platforms simply cannot reach. However, this same utility heightens ethical and policy considerations, particularly regarding surveillance in private or sensitive spaces. As the technology advances, clear guidelines will be needed to balance the operational value of accessing otherwise inaccessible areas with concerns around privacy, proportionality, and responsible use, ensuring that these capabilities are deployed in support of humanitarian, safety, and legitimate security objectives.
