Project Description
"; echo ""; echo "The AI-Based Smart Border Surveillance Robot with Thermal Vision is an intelligent IoT-enabled mobile robotic platform designed for continuous monitoring of authorized borders, restricted areas, industrial perimeters, campuses, forests and remote inspection zones."; echo "
"; echo ""; echo "The robot uses an ESP32 microcontroller as the main IoT controller. The system collects real-time information using thermal sensors, PIR motion sensors, ultrasonic distance sensors, GPS modules, environmental sensors and battery monitoring circuits."; echo "
"; echo ""; echo "The collected data is transmitted to an n8n automation platform through Wi-Fi or another authorized communication network. An AI Agent analyzes the sensor data and generates an event interpretation."; echo "
"; echo ""; echo "When a significant thermal or motion anomaly is detected, the system automatically generates an event, sends the event to the AI Agent, stores the data in Google Sheets, updates the ThingSpeak cloud dashboard and sends Telegram text and voice notifications to the authorized operator."; echo "
"; echo ""; echo "The system also monitors battery voltage, current consumption and power usage. AI-based power consumption prediction can estimate future battery usage and identify abnormal power consumption."; echo "
"; echo ""; echo "The robot is designed as a monitoring and alerting system. Final decisions remain with authorized human operators."; echo "
