Published in the proceedings of the IEEE International Symposium on Safety, Security, and Rescue Robotics, this work builds upon earlier generations of CRC suits that enabled real-time video streaming, positional tracking, and behavior analysis during search-and-rescue missions. While the original CRC suits demonstrated strong utility in field deployments, operational challenges were identified—most notably overheating of onboard electronics and slippage of the suit due to changes in inclination across the dog’s back.
The improved design introduces heat-mitigation strategies targeting thermal issues generated by components such as Wi-Fi modules and cameras. These protections allow the upgraded suit to operate reliably in temperatures exceeding 40 °C, broadening its applicability in hot-climate disaster zones. Simultaneously, the authors addressed the instability of the suit by adjusting chest-belt length to prevent unwanted inclination that previously hindered data capture and impaired the dog’s movement.
Beyond functional refinements, the researchers prioritized canine welfare by decreasing the suit’s overall weight by 18.3% (now 1.2 kg) and reducing its physical footprint. These modifications lessen mechanical load on search-and-rescue dogs, supporting sustained mobility and endurance during missions and extended training scenarios.
To validate the suit’s real-world performance, prototypes were deployed to search-and-rescue teams across eastern and western Japan. Handlers used the suits during training operations and disaster-preparedness exercises, confirming that the enhancements improved comfort, usability, and field reliability while maintaining critical sensing and communication functionality.
The study demonstrates how iterative engineering, grounded in direct feedback from canine teams, can expand the capabilities of cyber-enhanced working-dog technologies while safeguarding canine well-being. This evolution points to future avenues where robotics, sensor design, and animal-centered engineering converge to support more effective and humane disaster-response systems.
