      Summary

      In this lesson, students explore how sensor-based robotic systems can be used to monitor and protect the environment. Through hands-on programming with the FOSSBot robot and its visual programming environment, they connect sensors, create automated patrol systems, and develop a basic environmental monitoring system that detects obstacles, measures noise pollution, and identifies light pollution. Working in teams, students go through structured activities that combine theoretical understanding with practical application, progressively building their project from basic sensor control to a fully functioning automated environmental patrol system. This approach cultivates problem-solving, collaboration, and environmental consciousness along the way.

      Introduction

      Environmental monitoring systems are an essential application of modern automation technologies, helping reduce human impact and improve safety in public and private spaces. This module introduces students to key concepts in physical computing by using sensors such as photoresistors and ultrasonic detectors connected to a programmable robot (FOSSBot). Through hands-on activities, students learn how sensors collect data from the environment and how automated systems can make decisions based on this data. They apply conditional logic in programming to control LEDs, creating a smart environmental patrol system that only activates under specific conditions (e.g., low light and obstacle detection). This not only reinforces computational thinking but also raises awareness of technology's role in environmental protection, energy efficiency, and sustainable living.
