Protective Behavior Model for Smart Dog Robot in Real-time Human Safety Application

Abstract

With the rising frequency of harassment, assault, and theft incidents—particularly those targeting vulnerable individuals—there is an urgent need for proactive, intelligent, and autonomous safety systems capable of real-time threat detection and response. This paper introduces a protective behavior model for a quadruped robotic dog designed as a personal security companion capable of identifying potential dangers, alerting nearby authorities, and initiating protective actions. The proposed model integrates artificial intelligence (AI), Internet of Things (IoT) communication, and multisensory awareness to simulate human-like protective instincts. The robot dynamically transitions among three operational states—normal, alert, and defense—based on real-time data analysis from sound, motion, gas, and flame sensors. Upon detecting a threat, it can activate alarms, send live video streams and geolocation data to law enforcement, and execute safe, non-harmful deterrent actions such as audible warnings or repositioning itself strategically. The system’s architecture and workflow are validated through simulated testing in urban emergency scenarios, demonstrating efficient coordination between perception, decision-making, and action layers. The proposed smart dog robot bridges the gap between passive surveillance and active personal defense, marking a significant step toward human-centered robotics for real-time safety in public and domestic environments.
